What it is

The Elucian CU1MCB40B is a single-pole miniature circuit breaker rated at 40 A with a B curve trip characteristic and a 6 kA breaking capacity. It provides overcurrent and short-circuit protection on a single pole. The device is intended for use in consumer units and distribution boards.

Before you order

  • Confirm that 40 A and a B curve match the circuit design and the device being replaced.
  • Confirm that the 6 kA breaking capacity is adequate for the prospective fault current at the point of installation.
  • Confirm that a single-pole device suits the outgoing way being protected.
