It is possible to attach closely if there is no problem about the insulation distance between live parts such as a termi

It is a tripping zone which instantly trips, when significantly overcurrent such as short-circuit currents flow.

The degess of protection for ACB is IP20 as standard (under the condition that front door is closed). For MCCB and ELCB,

In that case, the rated current and the rated voltage shall be reduced. Refer to the table of derating factors as below.

IEC 60947-2 is an international standard for circuit breakers. The rated voltage for the applicable circuit breaker is 1

It is from -25 to 55℃ in Trip or OFF position. However, it shall be in an environment without condensation and freezing

It is overcurrent tripping characteristic zone which exceeds the rated current and does not exceed short time tripping z

It is possible to modify to Rear-connection type by Mitsubishi's certified staff.
