Description

Voltage Operated Earth Leakage Circuit Breaker , Outdoor Circuit Breaker

GENERAL


STC series adjustable residual current circuit breaker is suitable for AC 50/60Hz,230/400V circuit,prevents from overloading,short-circuit etc.On the occasion of shock hazard or earth leakage,it will trip immediately.At the same time,the rated current of overload protection can be adjustable.
The mccb can be sorted to C type (basic),L type (standard),M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity.
The mccb has the features small volume, breaking capacity high, electric arcing short ,anti-vibration. It is the ideal product for application in land and ship.

An Earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use Residual Current Circuit Breakers which instead detect leakage current directly.

The main purpose of Earth leakage protectors is to prevent injury to humans and animals due to electric shock.

There are two types of Earth-leakage circuit breaker:

· voltage operated (referred as ELCB in this article) and,

· current operated (referred to as RCCB in this article).
