Silver alloy contact

Circuit breakers generate high-temperature arcs during protection and manual operation. The use of silver material can effectively prevent the melting of contact points caused by high-temperature arcs, thereby extending the service life of the circuit breaker and improving its breaking capacity.

Copper conductors and coils

The use of high-purity copper as the coil and the main conductor material to reduce the internal resistance and enhance the conductive properties, the use of galvanized exposed terminals, corrosion resistance, and extended service life.

Arc extinguishing and heat dissipation structure designed for dc circuit

As the DC current is not pass through the zero point, DC circuit breaker on-off instantaneous high temperature arc is not easy to extinguish, so the DZ47Z-63H circuit breaker built-in arc extinguishing grids, heat sinks, arc-absorbing magnets and arc-extinguishing structures, they can effectively eliminate the DC arc, also in this case, DC circuit breaker can be used for AC circuits, but the AC circuit breakers can't be used for DC circuits.

Flame retardant material housing

The use of high-temperature resistant flame-retardant plastic as the shell material, can withstand the line short-circuit instantaneous high temperature, when the line current exceeds the circuit breaker to withstand the limit current, in the non-combustible state, the shell and the internal structure will not be immediately deformed, can support the circuit breaker for a longer period of time to disconnect the circuit. And circuit breaker supports install accessories such as MX shunt trip release, OF auxiliary, SD alarm, etc.

Type C trip curve

t(s): time

I/In: current multiplier

When the actual line current current exceeds the rated current of the circuit breaker, the circuit breaker starts to activate the thermal overload protection, but it is not immediately de-coupled, but proceeds slowly, and the de-coupling time decreases with the increase of the current, and the circuit breaker is immediately trip when the circuit current exceeds 5-10 times of the rated current of the circuit breaker. When the circuit is short-circuited, the current current usually exceeds 10 times the calibrated current, and the circuit breaker is immediately trip.

Non-polarized

Support current double flows

The breaker works fine, but I paid extra for faster shipping which wasn't faster.
