Earth Leakage Circuit Breaker(ELCB), Residual Current Device(RCD), Residual Current Circuit Breaker(RCCB)
Brand Name: Meba
Model Number: MB7L2-63
Type: Residual Current Circuit Breaker or Residual Current Device
Poles Number: 2P


1. MB7L2-63 series Residual current breaker(without over-current protection) is suitable for the line of AC 50/60Hz, voltage 240V(2 pole)/415V(4 pole),rated current up to 80A.

2. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage .

3. It is applicable to industrial area, commercial area, tall building and civil house.
