Because of their quick make-and-break design and excellent arc-quenching capability, Union miniature circuit breakers are suitable for
DC applications. For MCBs designed for AC use but applied in DC installations, the following considerations must be observed:
For overload protection, both poles of the MCB must be connected. Under these conditions, the tripping characteristic of the MCB in
DC is similar to that in AC.
For short-circuit protection, both poles of the MCB must be connected. Under these conditions, the tripping characteristic of the MCB
in DC is approximately 40% higher than in AC.

MCB are designed and calibrated to carry their rated current and to operate within their specified thermal time/current zone at 30 °C.
Testing is carried out with the breaker mounted individually in a vertical position under controlled conditions.
If the circuit breaker is required to operate in environments that differ from these reference conditions, correction factors must be
applied to the standard data. For example, when operating at ambient temperatures higher than 30 °C, the breaker will trip at
progressively lower currents within the designated time/current zone.

Because of their quick make-and-break design and excellent arc-quenching capability, Union miniature circuit breakers are suitable for
DC applications. For MCBs designed for AC use but applied in DC installations, the following considerations must be observed:
For overload protection, both poles of the MCB must be connected. Under these conditions, the tripping characteristic of the MCB in
DC is similar to that in AC.
For short-circuit protection, both poles of the MCB must be connected. Under these conditions, the tripping characteristic of the MCB
in DC is approximately 40% higher than in AC.

MCB are designed and calibrated to carry their rated current and to operate within their specified thermal time/current zone at 30 °C.
Testing is carried out with the breaker mounted individually in a vertical position under controlled conditions.
If the circuit breaker is required to operate in environments that differ from these reference conditions, correction factors must be
applied to the standard data. For example, when operating at ambient temperatures higher than 30 °C, the breaker will trip at
progressively lower currents within the designated time/current zone.

Miniature Circuit Breaker
The summation current transformer is usually designed as a ring-shaped transformer. Permalloy is commonly used as the magnetic
material, while newer types may employ advanced magnetic materials with nanocrystalline structures. The core of a voltage-dependent
RCCB is a trip relay with a permanent magnet (PMR).
In idle state, the relay armature is held by the permanent magnet. Once current is conducted into the excitation coil, the attraction force
of the magnet is reduced, allowing the spring force to move the relay armature. Due to its simplicity and proven reliability, this type of
polarized relay is widely used.
The switching mechanism of the RCCB must be both sensitive and strong enough to ensure reliable operation of the contacts. Each load
current path must be capable of carrying the rated current throughout the service life of the device. The distance between open contacts
must provide safe insulation, and contacts must be protected from surge currents and presumed short-circuit currents.
For multi-pole types, the neutral conductor (N) contacts must close before and open after the phase conductor (L) contacts. This
prevents unwanted surge voltages in the phases.All RCCBs must be equipped with a testing device consisting of a test button (T) and a
resistor (R) appropriate to the operating voltage. The test button must be easily accessible to the user. When pressed, it simulates
residual current using the test resistor, forcing current to flow outside the summation transformer.

tripping (IEC/EN 61008).
• Type A: Detects alternating and pulsating DC residual currents, possibly including smooth DC residual currents up to 6 mA (IEC/EN

• Type B: Detects all types of residual currents (alternating, pulsating DC, and smooth DC residual currents) (IEC/EN 62423). Type B
devices are essential in installations with frequency inverters, photovoltaic systems, and equipment with power semiconductors.
The fundamental difference between Type AC, A, and B lies in the type of material used for the core of the summation current
transformer.

Functional Principle of RCCB
Every Residual Current Circuit Breaker (RCCB) has three basic components;
Toroidal current transformer, Trip relay, Switching mechanism.
The function of these components is to detect and evaluate the residual current and to interrupt the power supply if the residual current
exceeds a specified value. For correct operation of an RCCB, all live conductors of the protected circuit—or at least as many conductors as
necessary for proper appliance function—must pass through the summation current transformer.
An RCCB works on the principle of comparing currents in live conductors passing through this summation toroidal current transformer.
Under normal conditions (no phase-to-ground fault), the vector sum of instantaneous current values equals zero. The magnetic fluxes
from the various conductors cancel each other out inside the transformer core.
When an earth fault occurs, part of the current flows outside the live conductors, creating an imbalance. This imbalance induces a
magnetic flux inside the transformer core, and the output winding generates a current that activates the trip relay. The relay then triggers
the switching mechanism, causing the contacts of the RCCB to open and disconnect the circuit.

same applies analogously for

Residual Current Circuit Breaker
General
Residual Current
The RCO Series Residual Current Operated Circuit Breakers with Overcurrent Protection (RCBOs) are suitable for AC systems with a
frequency of 50/60 Hz, rated voltage 240V/415V, and rated current up to 63A. They provide protection against overloads, short circuits,
and residual currents.
The RCBO quickly disconnects the power supply if a person is at risk of electric shock or if the circuit leakage current exceeds the preset
value, ensuring the safety of both people and equipment.
RCO Series RCBOs can be applied in residential, commercial, industrial, and high-rise building installations. They are also suitable for
infrequent switching of lines under normal operating conditions.
The series includes devices classified according to detectable residual current waveforms:
Type B: Protection against sinusoidal AC residual currents, pulsed DC residual currents, alternating residual sinusoidal currents up to
1000 Hz, pulsating DC residual currents, and smooth DC residual currents, whether applied suddenly or gradually.
Type B+: Extended sensitivity version of Type B, offering protection up to higher frequency ranges (kHz level), suitable for installations
with power electronics, photovoltaic systems, and frequency converters.
Technical parameters
The tripping characteristic curves are as shown below.

Test instrument: Use a 1000 V DC megohmmeter.
Test conditions: With the circuit breaker in the open position, perform insulation resistance measurements as follows:
1.Between inlet and outlet connection terminals: 1–2, 3–4, and 5–6
2.Between terminals 1, 3, and 5 (connected by wires) and the circuit breaker casing (casing covered with metal foil)
3.Between the undervoltage release of the main circuit and the circuit breaker casing
Insulation resistance requirement: Not less than 20 MΩ.
Alternative test method: If a 1000 V DC megohmmeter is not available, a powerfrequency withstand voltage tester may be used.
Apply 3000 V AC for 1 minute across the same test points specified above.
Each circuit breaker is factory-tested for insulation in compliance with applicable standards.
