Product Description

HKKM1 series of moulded case circuit breaker (drawable version) is new type product developed and manufactured by adopting international advanced technology. It is designed with rated insulation voltage 800V and used for circuit of AC50Hz, rated operating voltage AC 400V or below rated operation current up to 800A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current, short circuit and under voltage, the product is capable of preventing damage of circuits and supplying units The product conforms to IEC60947-2 stard.

1) HKKM1E Series of intelligent moulded case circuit breaker provides communication ports and use microprocessor-based releases, which provide protective functions against overloads (L). Short-circuit's inatantaneous (I) and selective (S) and earth faults (G).

A. One communication interface and displaying interface on the left side: RS-232 or RS-485. Configurable to DNP 3. Level 2, MODBUS ASC_or MODBUS RTU
B. Remote setting of parameters, protection functions, unit configuration and communication.
C. Transmission of measurements, statuses and alarns from circuit-breaker to system.
D. Transmission of events and maintenance data from circuit-breaker to system.

2) Typical Application Diagram.
HKK Portable programming device can be uesd to adjust settings of all protective characteristics of the breaker according to Operation Manual of the device.

3) HKK-CD Pisplayer is conneted to breaker and to display infor mation of current and faults during operation.
