1.Internatonal standard: IEC 2.Authoritative certificate:CCC, CE,EU, TUV & ROHS 3.Rated voltage:144V,DC current:400A

1.Application

GSZ1 series D.C. contactor is mainly used for DC operating voltage to 48V or 144 V,operating current respective to 100A,200A,400A DC circuit,for making or

breaking the circuit .Product is mainly used for control electric car,low voltage converter,engineering machinery and use of DC power supply situation.

2.Structure feature

The action mechanism of direct-acting,contact for double breakpoint bridge contact;

The main circuit wiring should match circular or peep mouth cold-pressed terminal;

Can be convenient handling auxiliary contacts,model for F4-11;

Coil wiring using plug-in type,quick and convenient wiring;

C-type and L-type mounting accessories for easy installation.

 3.Working and installation condition

Ambient air temperature is -25°C~+40°C ,the 24h average value is less than  +40°C ;

When temperature is +40°C , relative air humidity is not exceeding 85%,with lower temperature higher ralative humidity willbe permitted. By the temperature change to occasionally produce dews,should take special measure;

when mounted position altitude exceed 3000 meters,every rise 500 meters own 10% use, highest do not exceed 4500 meters;

applicable duty; uninterrupted duty(DC-1),intermittent periodic duty-type.
