AC Contactor
The UNDW1 Series Intelligent Air Circuit Breaker (hereinafter referred to as circuit breaker) is designed for distribution networks with AC
50 Hz, rated working voltages of 400 V and 690 V, and rated currents up to 6300 A. It is used to distribute electrical energy and to protect
lines and equipment against overload, undervoltage, short circuit, grounding, and other faults.
The circuit breaker is equipped with an intelligent controller featuring precise selective protection and multifunctional capabilities,
ensuring comprehensive protection across electrical systems. It is particularly suitable for distribution networks where improved power
supply reliability and prevention of unnecessary outages are required.Among them, the 2H and 3H intelligent controllers feature
communication interfaces that allow easy connection with field bus systems.
They support four remote functions: telemetry, remote regulation, remote communication, and control, meeting the requirements of
modern control automation.
Leakage protection can be achieved by configuring a leakage current transformer together with the intelligent controller.
The circuit breaker with rated currents up to 1000 A can also be used for overload, short circuit, undervoltage, and ground fault
protection of motors in AC 50 Hz and 400 V networks, and is suitable for infrequent motor starting under normal conditions.
The UNDW1 Series is available in fixed type and withdrawable (drawable) type versions, offering flexibility for different installation and
maintenance requirements.

Thermal
Relay
The UNTR1 Series Thermal Relays (UNTR1-25, UNTR1-36, UNTR1-93, UNTR1-150, UNTR1-200, UNTR1-630) are suitable for use in circuits
with rated voltages up to 660 V
and rated currents up to 93 A, at AC 50/60 Hz, providing reliable overcurrent protection for AC motors.
These relays feature a differential mechanism and temperature compensation, ensuring stable performance under varying operating
conditions. The UNTR1 relays can also be directly
mounted onto CJX2 series AC contactors, allowing convenient assembly and enhanced motor protection.
The product conforms to IEC 60947-4-1 standard.

The UATA Automatic Transfer Switch (ATS) is a PC-class infrequent change-over switch with a two-station design (commonly used for
main power supply A and backup power supply B). It is suitable for AC systems with AC 50–60 Hz and rated currents from 6 A to 63 A.
The main function of the ATS is to ensure continuous operation. When the main power supply (A) fails, the ATS automatically switches to
the backup power supply (B) within 50 milliseconds, effectively preventing power outages and ensuring reliable system operation.

Some electrical appliances used in homes and workplaces need to operate periodically at certain times during the day (for example, floor heaters,
electric water heaters and storage water heaters, lighting fixtures, or other similar devices). To meet such needs, programmable time switches using
electro-mechanical technology have been designed and manufactured.
Our Union brand time switches have the following features:
Equipped with a servomotor, offering precise timing capability.
Reserve function allows programs to continue for up to 100 hours during power cuts.
Operates with 220 V / 50 Hz supply voltage.
Independent auxiliary contact, usable in both AC and DC circuits up to 400 V.
96 notches on the programming disc, each corresponding to 15 minutes.
24 hours of the day are displayed on the same disc.
Can operate in two modes: manual and automatic.
Mounted on a standard 36 mm rail (per En50022).
Due to the small and sensitive servomotor, it should not be installed next to contactors or similar devices.
Must be protected by an independent thermal-magnetic circuit breaker (automatic fuse).
