Introduction
The DAB6-63 4-5KA miniature circuit breaker was developed by Dada engineers to meet GB10963 and IEC60898 standards. The circuit breaker features stable usage, precision protection, short opening time, high breaking capacity index, and the overall design is notably small.

Widely used for overload protection for contactors, relays and other pieces of electrical equipment.

Main functions: short circuit protection, overload protection and isolation.

Release types
Type B circuit breaker - for small circuit breakers which require quick release and small short circuit currents, allowed peak current <3in. Suitable for protecting secondary circuits of transformers
Type C circuit breaker -for most of the electrical circuits, and will not open when passing high short-time peak current. The passable peak current is up to 5in. Suitable for protecting general electrical circuits
Type D circuit breaker- for switching equipment of high peak current (10in), such as circuit can be used to protect the primary circuit of transformer, electromagnetic valve and start the electric machinery.
