40A 250A 400V C Curve MCCB Circuit Breaker 230V 3 Pole

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
