Earth Leakage Circuit Breaker

EarthLeakage Circuit Breaker

Description
An earth leakage circuit breaker (ELCB) is a safety device used for protectingagainst personal electric shock hazard, with high earth impedance. It is alsoused for unfrequented switchover of circuits under normal conditions. In thecircuit of AC 50~60Hz, single phase 230V (220V), three phase 400V (380V), ourearth leakage circuit breaker is increasingly used many places, such asindustrial & mining enterprises, commercial buildings, housing, etc. F360ELCB without over current protection is in conformity with the standards ofGB16916.1, IEC1008, and BS 4293 etc.

Features
1. Offer protection against earth fault/leakage current and isolating function.
2. High short-circuit current withstand capacity.
3. Applicable to terminal and pin/fork type bus-barconnection
4. Fire resistant plastic parts can withstand abnormal heating andstrong impact.
5. Disconnect the circuit automatically when earth fault/leakage current occursand exceeds the rated sensitivity
6. Independent of power supply and line voltage, and freefrom external internal interference voltage fluctuation.
