 Circuit Breaker (L7) |
Product Description
L7 provides ground fault protection by monitoring the leakage of current To ground. The L7 will trip when ground faults are detected in excess of the GF trip rating of the RCCB. The product can also detect and trip when there Is a current differential between the live line and neutral line, and therefore Protect people from electric shock, These devices provide GF protection and life protection and are used in seres with standard MCBs which provide Overload and short circuit protection. The L7 can be used as a main device Providing GF and life protection for several MCB branch devices.
