Snap Acting Relay has sensitive response and precise action,and can quickly send out a signal and cut off the power supply.Once a sudden pressure change occurs inside the transformer,it can prevent serious accidents such as deformation and bursting of the fuel tank.
Technical Parameters:
✦ Ambient temperature:-45~+50℃
✦ Relative humidity:no more than 95%at+20℃
