Project Description

QA 240v electrical circuit breaker ac mcb switch type connection

QA 240v electrical circuit breaker ac mcb switch type connection is mainly for suitable for overload and short circuit protection. It adopt hydraulic magnetic trip instead bimetal .So it has a high sensitivity and it is also not effected by the ambient temperature . It is especially used for illumination and distribution in industry and commerce. They are mainly used for overload and short-circuit protection within the circuit of AC 50Hz/60Hz, rated voltage of single pole or double up to 240V, three poles up to 415V. They can also be used for an unfrequent switch-over of the circuit and illumination under normal conditions. They are comply with IEC 157-1973, BC4752-1977 and BS 3871 part 1
