KXB1-32 series residual current movement circuit breaker(Phase line+Neutral line)

Application:

KXB1-32 series high breaking capacity miniature circuit breaker apply to single phase residential circuit of AC 50Hz, rated voltage 230V or lower than that, for protecting electric circuit overload and short circuit. This product have high breaking capacity, small volume etc advantage, width only 18mm. Null line and fire line can cut off simultaneously, avoid personal dangerous or fire disaster which may caused by the situations of fire line and null line be connected wrongly or null line to earth. It's the most optimal distribution protection switch for residence building.  

This product meets the following criteria:

IEC60898,GB10963

Model No. and meaning:

Main technical parameter:

Note:

Resistance hot and humid resistance type: II type(relative humidity is 95% when temperature 55℃)

Wire connecting adopt connection terminal with clamp, can connect guide line ≤10mm²

Over current characteristic tripping table:

Action characteristic tripping curve:

Overall and installation size:

Installation: Can be installed into distribution box which is suitable for multi9 component.

Bimetal:   Actually, it contains three metals iron, copper, cadmium, galvanized. Three metals with different coefficients of thermal expansion, bending cause thermal Pick reflect and making the breaker disconnect. This is the most import parts of the circuit breaker.  The Bimetal is the use of different materials under different breaker amperage.

Coil:  It's the important parts for the reaction of the Magnetic Trip. It's always 9 ring. As a matter of fact, the number of Coil with Different Amperage.For example, 1A reaches over 100 ring, and 63A is used to 56 ring. The Diameter Thickness is also different for Amperage.

Action Contactor(Sliver Point): It's the main point for the Reaction of Trip. Under normal conditions, keeping closed. When overload and short circuit, It will be breaking.

Arc Chute: Playing a role in destroying the arc. Generally tend to produce a large number of Moving and Static Contactor from the contactor, arc, even emerge spark.
