Product details

The EZ9F34332 carries a 4.5 kA Icn at both 230 V and 400 V AC, conforming to IEC 60898-1. The service breaking capacity Ics equals Icn at 100 % — meaning after clearing a fault at its full rating the breaker remains functional and can be reclosed. For a panel builder, that simplifies coordination: you can place this MCB downstream of a higher-rated upstream device (e.g., a 10 kA MCCB) and the selectivity break is clean at the 4.5 kA threshold.

Thermal-magnetic trip and environmental range

The thermal-magnetic trip unit combines a bimetal element for overload protection and a solenoid for short-circuit. The C-curve magnetic trip is set at 5 to 10 times In, so a 32 A breaker trips instantaneously between 160 A and 320 A. Operating ambient temperature spans -25 to 60 °C with 95 % relative humidity; storage range is -40 to 85 °C. The IP20 finger-safe terminals accept up to 35 mm² rigid or 25 mm² flexible conductors, torqued to 3.5 N·m.

Frequently asked questions

What is the breaking capacity of EZ9F34332?

The EZ9F34332 has a rated breaking capacity Icn of 4500 A at both 230 V AC and 400 V AC, 50/60 Hz, conforming to IEC 60898-1. The service breaking capacity Ics is 4.5 kA at 100 % of Icn.

What is the closest alternative to EZ9F34332 in the Easy9 range?

Within the same Easy9 family, a higher-current variant like a 40 A 3P C-curve MCB would share the same DIN-rail footprint and terminal style, but the trip threshold and breaking capacity differ — verify coordination for your specific load before substituting.

What compliance documentation does Schneider provide for EZ9F34332?

The EZ9F34332 is certified to IEC 60898-1 and carries an impulse withstand voltage of 4 kV conforming to that standard. It is suitable for isolation per IEC 60898-1. For RoHS, REACH, and UL declarations, refer to the manufacturer's compliance documentation available on request.
