4.2 Release pattern and accessories code

• Rotary handle operation device

The mechanism is used in moulded case circuit breaker to operate the draw-out panel. Power distribution panel and supply box outside the panel by turning the handle, and to ensure the door of panel would not be opened when the breaker being on.

The hand-drive mechanism can be equipped with two types of operation, one is “A" model square handle, the other is “B" model round handle.

SHT: Shunt release; UVR: Under-voltage release; AX: Auxiliary contact; AL: Alarm contact

Under-voltage release

According to user's demands, accessories could lead to direct wire out coming or line wiring terminals could be added(please mark out in case of making order).

• Under-voltage release

Wring diagram of the under-voltage module connected externally (the internal accessories in the dotted frame) Ue: AC50/60HZ 230V, 400V

Shunt release

When the operation voltage is 35%\~70% of the rated voltage, the under-voltage release should make the breaker trip correctly.

When the operation voltage is 85%-110% of the rated voltage, the under-voltage release should make the breaker close.

In case of the operation voltage less than 35% of the rated voltage, the under-voltage should prevent the breaker from closing.

Note: Only the under-voltage release should be energized in advanced, the breaker could be re-cramped and turned-on, otherwise the breaker will be damaged.

• Shunt release

Scheme of wiring(the internal accessories in the dotted frame)

“K” is the slow motion switch normal-close contact connect the coil in series in the shunt release. It turnson or turns-off voluntarily as soon as the breaker on or off.

Alarm contact

3. Trip Units Main Technical Parameter

• Thermal Magnetic Trip Units

• Basic Protection Functions

(L) Protection against overload

This protection function trips when there is an overload with inverse long-time delay trip according to an inverse time curve (l2t=k). The protection cannot be excluded.

(S) Protection against short-circuit with time delay

This protection function trips when there is a short-circuit, with long inverse time-delay trip (I2t=k ON) or a constant trip time (I2t=k OFF).The protection can be excluded.

(I) Instantaneous protection against short-circuit

This protection function trips instantaneously in case of a short-circuit. The protection can be excluded.

(G) Protection against ground fault

The protection against ground fault trips when the vectorial sum of the currents passing through the current sensors exceeds the set threshold value, with long inverse time-delay trip (I2t=k ON) or a constant trip time (I2t=k OFF). The protection can be excluded.

4. Accessories Service Releases

• Shunt Trip-SOR

Allows circuit breaker opening by means of an electric command. Operation of the trip is provided for a voltage between 70% and 110% of the rated power supply voltage value Un, both in alternating current and in direct current. For LKM3 T1, T3, T5 and T6, the SOR shunt trip is fitted with a limit contact for cutting off the power supply in the open position and with the release tripped.

T1、T3

T5-T6

• Testing extension for service releases

Available for LKM3-T5 and T6, this allows the service releases to be supplied with the circuit breaker in the removed position. With the circuit breaker in safe conditions, i.e. isolated from the power circuits, this makes it possible to carry out blank tests of the circuit breaker functionality.

• Undervoltage release-UVR

The undervoltage release opens the circuit breaker due to lack of release power supply voltage or due to values under 0.7x Un with a trip range from 0.7 to 0.35x Un. After tripping, the circuit breaker canbe closed again with a voltage higher than 0.85 x Un. With the undervoltage release de-energised, it is not possible to close the circuit breaker or the main contacts.)

4.2 The internal accessories of the breaker

Under-voltage release

Us: AC50/60HZ 400V, 230V

When the operation voltage is 35%\~70% of the rated voltage, the under-voltage release should make the breaker trip correctly.

When the operation voltage is 85%\~110% of the rated voltage, the under-voltage release should make the breaker close.

In case of the operation voltage less than 35% of the rated voltage, the under-voltage should prevent the breaker from closing.

Note: Only the under-voltage release should be energized in advanced, the breaker could be re-cramped and turned-on, otherwise the breaker will be damaged.

Shunt release

Us: AC50/60HZ 230V 400V; DC110V 220V

Shunt release

The shunt release should make the breaker trip reliably when the operation voltage is 70%-110% of the rated control voltage

LKM5 Series Moulded Case Circuit Breaker

1. Application

LKM5 series MCCB is suitable for industrial or commercial power and lighting with AC50/60Hz, rated working voltage up to AC600V/DC250V, rated current up to630A. It's a kind of economical breaker with the characters of stable and reliable function, beautiful appearance, small size and long life. It can be used for conversion of line and infrequent starting motor. It can also be attached to install the accessories which have protection function for avoiding loss- voltage, under voltage. The product can install connection line with front board and back board, it also can equip hand-operating apparatus or motoroperating apparatus to control in a remote distance.

2. Specification

The rated insulation voltage for this series of circuit breaker is 690V, the rated operating voltage is 600V, the rated frequency is 50Hz, the other rated values for the main circuit.
