A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.
This Multi9 C60H is a low voltage miniature circuit breaker (MCB). It is a 3P circuit breaker with 3 protected poles, 20A rated current and C tripping curve. The rated short circuit breaking capacity goes up to 15kA at 415VAC conforming to EN/IEC 60947-2 standard. This product complies with industrial standard EN/IEC 60947-2. It has been designed to offer enhanced protection by preventing, protecting equipment from electrical threats. This product protects from short circuit and overload. Its fast closing mechanism, overvolatge resistance and high performance limitation improve its service life. This product is dedicated for original equipment manufacturers (OEM) and control panel builders. It has an electrical endurance going up to 10000 cycles and a mechanical endurance going up to 20000 cycles. The Ue operational voltage is 240VAC. The Ui rated insulation voltage is 500VAC.
