CM1 series Moulded Case Circuit Breaker

CM1 series Moulded Case Circuit Breaker is one of products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 550 and 800V and used for circuit of AC 50/60Hz, rated operating voltage AC 400V (or below), rated operating current up to 1600A for infrequent changing over and starting of the motors.The products conforms to IEC60947-2 standard.

The rated insulation voltage of the circuit breaker is 800v.

It`s apply to the circuit` infrequent transitions which is 50Hz (60Hz), rated operating voltage AC690V and below (DC 250V and below), rated current 10A or 1250A as well as the use of motors with infrequent starts.

The circuit breaker which has the device with overload, short circuit and undervoltage protection can protect the prevent the circuit and the equipment of power supply from being damaged.

The circuit breaker has characteristics with a small size, high breaking capacity, short arc (part of the standard zero arc), anti-vibration to meet the demand for industrial electricity.

What`s more,it is an ideal product for the use of land and ships.

Normal Working Conditions

1.Elevation:≤2000m

2.Enviroment temperature:-5℃~+40℃(+45℃for Marine products)

3.the tolerance of moist air effect; the tolerance of salt mist,oil mist, mould and nuclear radiation effert

4.Maximum inclination of 22.5 degrees.

5.It can work reliably when the ship is in normal vibration; it can work reliably under the earthquake(4g)

6.And without the risk of explosion in the medium ,and medium nonmetal corrosion and damage to the insulation of gas and dust where conductive. In the absence of rain and snow hit the lacal.
