KXM1GQ-63 series single phase overvoltage, undervoltage, overvoltage & undervoltage protection circuit breaker

Application:

KXM1G-63, KXM1Q-63, KXM1GQ-63 series single phase overvoltage, undervoltage, overvoltage & undervoltage protection circuit breaker apply to the circuit of rated current lower than 63A, AC 50Hz, rated working voltage 230V, overvoltage protection setting parameter is 270±5%, undervoltage protection setting parameter is 170±5%, used for electric equip and device of AC distribution system for overload, short circuit and overvoltage & undervoltage protection. It's ideal product for residential, hotel, hospital, emporium, office building.

This series miniature circuit breakers meet the following criteria:

GB10963.1,IEC61009-1

Model No. and meaning:

Structure summarize:

KXM1GQ-63 series single phase overvoltage, undervoltage, overvoltage & undervoltage protection circuit breaker consist of moulded case, operate institution, thermal tripping mechanism, electromagnetic tripper contact mechanism system, arc-extinguishing system, circuit plate of overvoltage & undervoltage protection etc, have overload and short circuit protection function. Special design, product have 6kA short circuit capacity. Mechanical life reaches more than 2000 times, elegant appearance, TH35-7.5 standard mounting rail, safe and comfortable handle operation mode, overvoltage & undervoltage protection parameter can be set according to client's requirement. Should pay attention on firing line while wire connecting, power supply top in down out, easy to install.

Main technical parameter:

Overall and installation size:

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.
