Eaton.com Eaton air circuit breakers - for cost-effective, optimized solutions. The IZMX16 is the smallest The IZMX40 is a circuit air circuit-breaker in his class breaker for up to 4000 A in worldwide: a volume of a 3200 A circuit With a volume of only 24 dm3 breaker, without the need to and a front surface of only install any additional “busbar 0.092 m2 it is just slightly extensions” in the connection bigger than the size of a DIN area.

ARCON® IZMX breakers, combined with SAFETY ARCON®, help users to avoid damage and to protect people against arc faults as they can effectively be brought under control within 2 ms. They also protect against arc fl ashes that – due to their impe- dance - would not even cause a protective device to react.

Thanks to the powerful stored- energy spring, the circuit breaker will carry out the switch command sent to the magnetic coil in less than 35 ms. So the IZMX series circuit breakers are suitable for synchronisation tasks. Easy inspection and maintenance Inspection and maintenance can be conveniently performed on the draw-out breaker as the primary fi nger clusters (blue) and levering mechanism are part of the breaker instead of the cassette.
