Webheated front screen, lamps: front, rear, fog light, main switch/supply relay. 1) At rated voltage. 2) Current and time are compatible with circuit protection by a typical automotive fuse. WebEaton C441 Series motor protection relays continuously monitor the electrical parameters like current, voltage & phase balance in a circuit. The relays trip on detecting a fault condition and open the electrical contacts to interrupt the power supply to the circuit & protect it from damage. WebA protective relay is used to protect the device once the fault is detected within a system. Once the fault is detected, the fault location is found and then provides the tripping signal to the circuit breaker or CB. These relays work on the two principles like electromagnetic attraction & electromagnetic induction. cool greninja images
