4P 125A miniature circuit breaker

.Rated current up to 125A Energy limiting class:3

The handle being sealable or equipped with padlock bracket avoids dangerous operation changes(ON/OFF)

The handle provides a clear indication of the contact position

Adequate printing of all data on the front provides long-term identification

The emission of ionized gases is limited to the severest restrictions: 45 mm grid distance

This MCB may be extended with:a wide range of RCDs and RCBO

Magnetic release 

An electromagnet with plunger ensures instantaneous tripping in case of short circuit.

The standard leaves the calibration of magnetic release to manufactures decision.

Manhua MCB series MK1-125 offers instantaneous tripping ranges

                                                                                                           -release C:5~10In

                                                                                                           -release D:10~20In

Thermal release

The release is initiated by a bimetal strip in case of overload

The standard defines the range of release for specific overload values

Reference ambient temperature is 40°C

Test Current	Tripping Time
1.05In	t≥2h(In 63A)	Non-Tripping
1.30In	t<2h(In 63A	Tripping
