TOMZN 4 Pole MCCB Moulded Case Circuit Breaker 125A (3 Phase)

TOMZN 4 Pole MCCB 125A – Moulded Case Circuit Breaker for 3 Phase Supply

The TOMZN 4 Pole 125A MCCB is a heavy-duty moulded case circuit breaker built to protect your three-phase main line from overload and short circuit. When a fault hits, it trips and cuts the supply before cables, motors and appliances get damaged, and lets you safely isolate the whole installation with one switch.

With 4 poles, it switches all three phases and the neutral together, giving complete isolation for maintenance and safer changeover between sources.

Where to use it

• Solar systems: AC-side protection on the inverter output / feed to the main panel
• Generator feeds: protect and isolate the generator line into your DB
• Distribution boards (DB panels): main breaker for a 3-phase panel or sub-panel
