GSZ2 400A 24V 48V General Electric Series Normal Closed High Voltage DC Contactor

Product defination:

The GSZ2-SI series of single-pole DC contactors for low-voltage inverters are mainly used for bypass current limiting resistors in low-voltage inverters. They are also suitable for starting and stopping battery vehicles and power switching in electric forklifts, traction locomotives, telecommunications, computers and other fields. Uninterruptible power system.

Structure Feature:

1.Action agency is directly operated type,contact is double breakpoints bridge type contact.

2.Natural interrupt fire.

3.The coil wiring provide two modes selection,fixed wiring screw mode and soft lead mode

4. Except 50SI/100SI,other specifications can be equipped with one open and one closed auxiliary contacts,mode for F4-11

5.Small size,light weight,low power consumption,high reliability.

Working and Installation condition:

1.Ambient air temperature is -25°~+70°C,average temperature is less than +40°C in 24hr

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

3.When mounted position altitude exceed 3000 meters,every rise 500 meters down 10% use,highest do not exceed 4500 meter.

4.Vibration frequency at fixed place:1-50Hz(1-10Hz frequency,amplitude 250/f²)

5.Impact acceleration:30m/s²

6.The pollution degree is "pollution degree 3"

7.Installation direction:free

8.Installation way: by screw

9.Applicable duty: uninterrupted duty (DC-1),intermittent periodic
