63A 300A 400V C Curve MCCB Circuit Breaker 230V 220V 3 Pole

Product Specification

63A/300A 230V/400V Heat Resistant MCCB Circuit Breaker 

Our MCCBs provide you unmatched circuit protection in alternative energy, commercial, industrial, mining, and military applications when protecting conductors against overloads and short circuits.
These circuit breakers are applied in panelboards, switchboards, motor control centers, control panels, combination starters, individual enclosures, and bus duct plug-in units.

Application

Our DZ15DDZ15D10-40A 50-100A 100-250A/3902□ type multifunctional auto protective switch is mixed with the protection functions of phase failure, over-current, short circuit faults, able to provide the automatic protection for the motors under AC 380V, 50Hz, also used to start motor non-frequently, further to some degree, prevent the accident of distribution transformer destroyed resulted from over-current because motors run at failure of one phase caused one phase of drop out fuse melted down.The merit of this switch has solved the problem that many switches can't take action while the one phase of drop out fuse is melted down, no matter drop out fuse melted down, low voltage fuse burnt, one phase of three phase motor is broken, which make it run at phase absence, it can perform the effective protection.

Using conditions

The altitude of the installation site is less than 2000m.

Ambient air temperature: the upper limit of ambient air temperature shall not exceed +40℃; The average ambient air temperature for 24h shall not exceed +35℃; The lower limit of ambient air temperature is not less than -5 ° C.

Atmospheric conditions: the relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40℃, and it can have a higher relative humidity at a lower temperature. When the monthly average minimum temperature of the wettest month does not exceed +25℃, the monthly average maximum relative humidity of the month is 90%, and the temperature change occurs on the surface of the product is taken into account.
