Schneider Electric Masterpact NW25H2 2500A 4P Air Circuit B

Schneider Electric Masterpact NW32HF 3200 A four-pole drawout switch-disconnector, supplied with its matching withdrawable cradle/chassis.

Heavy-duty low-voltage switching device suitable for use as a main incomer, bus-coupler or isolating switch in industrial distribution boards, generator systems, data centres and other high-current electrical installations.

This is a switch-disconnector, not a circuit breaker with an electronic protection trip unit. The photographed configuration corresponds to the Schneider Masterpact NW32HF 4-pole, 3200 A drawout version.
