Application

GNM1 E series itelligent mouldedcase circuit breaker is developed and manufactured by adopt-ing international advanced technology. It is supplied with rated insulating voltage 800V and used for circuit of AC 50/60Hz, rated operating voltage 400V, rated operating current up to 800A of the circuit breaker infrequent changing over and starting of the motors. The circuit beaker has protec-tion function of overload long delay inverse time, short circuit short delay time limit, short circuit in-stantaneous and under voltage, which can protect the line and power supply equipment from dam-age.

The circuit breaker can be mounted vertically(i.e. vertical) or horizontally. The Circuit breaker can not be poured into the line, that is, only 1 ,3,5 connect power cord;2, 4,6 connect load line.

The circuit breaker conforms to following standards:

IEC60947-1 GBIT14018.1 low-voltage switchgear and control equipment Part I: General

IEC60947-2 GB14048.2 low-voltage switchgear and control equipment, the second part of circuit breaker and annex with electronic over-current protection circuit breaker aditional requirement;

IEC60947-4 GB14048.4 low-voltage switchgear and control equipment contactors and motor starts;

IEC60947-5.1 GB14048.5 low-voltage switchgear and control equipment electromechanical control circuit electrical appliances.

GB22710 electronic controller for low voltage circuit breaker.

Main Performance Characteristics

GNM1 E ntelligent moulded case circuit breaker is belongs to B category with three grades protec-tion. In the short-circuit conditions, HM1 E has a fully selective cooperation with some other short-circuit protection devices in the same circuit.

With five tripping feature options. The users can adjust & set the tripping current according to the load current requirements

The energy of electronic release is provided by the circuit breaker itself. The current signal and the control source are from the toroidal current transformer which is installed in the circuit breaker.

With warning indication: When the load current exceeds the preset current, the LED on the circuit breaker cover indicates yellow;

With overload indication: When the load current exceeds the set current, the LED on the circuit breaker cover indicates red;

With a dedicated fire overload no-trip only alarm function. When the load current overload opera-tion, the circuit breaker does not trip, outputs a passive contact, drive the corresponding alarm de-vice;

Compliance with IEC60947 Appendix F of the electromagnetic compatibility requirements;

Dimensions are same to the same frame HM1 molded case circuit breaker, installation is inter-changeable.

Type and Meaning

Note:

1.Distribution without code, protection motor code: 2;

2.Electronic accessories are: 1 communication module, 11 communication with shunt. 111 communication with passive auxiliary contacts, IV overload alarm does not trip module, no electronic components code;

3.According to the number of poles of the product is divided into three poles and four poles, 4 poles N type: N pole over load current protec-tion, time parameter 100% automatic tracking phase line setting value, and N pole and other three poles ON-OFF Together(N pole turn off af- ter close);

4.Directly operation without code, motor operation: P indicate, turn handle: Z indicate.
