Residential 40A Moulded Case Circuit Breaker
Introduction
DZ47-63 high breaking miniature circuit breaker has the characteristics of advanced and reasonable structure, reliable performance, high breaking capacity, beautiful and compact appearance, etc.
Point, shell and other components are made of impact-resistant, highly flame-retardant materials. Suitable for AC 50Hz or 60Hz, rated working voltage 400V or less The rated current is below 6A to 63A. Mainly used for lighting, distribution lines and office buildings, residential and similar buildings The overload and short circuit protection of the equipment can also be used for infrequent breaking and conversion of the line under normal circumstances.

Structural characteristics
DZ47-63 high breaking miniature circuit breaker is composed of plastic shell, operating mechanism, contact arc extinguishing system, trip mechanism, etc. Shell used
High-flame-retardant, high-strength special plastics with strong impact resistance and light weight.
The parts of the circuit breaker operating mechanism are made of high-strength plastic products, which ensure the sensitivity and reliability while obtaining the lowest moment of inertia.
The time from the start of the short-circuit fault to the tripping mechanism is very short. The tripping mechanism consists of a bimetallic overload, inverse time tripping mechanism and short-circuit transient action
The electromagnetic mechanism is composed of two parts. The contact arc extinguishing system uses a special arc guide angle and arc extinguishing chamber, which has significant current limiting characteristics.
