Product details

It snaps onto a 35 mm DIN rail per DIN EN 60715 and accepts screw-type terminals for the main current circuit, with a wire range of 2x (1 to 35 mm²) solid or stranded, or 1x (1 to 50 mm²).

At 400 V AC the 3RV2332-4KC10 is rated for 50 kA, at 240 V AC for 100 kA, at 500 V AC for 8 kA, and at 690 V AC for 4 kA. For a 400 V panel with an available fault current of 50 kA or less, this breaker is a direct fit. The 100 kA rating at 240 V covers high-fault residential or light commercial subfeeds.

Motor power coverage

The breaker covers motor loads up to 22 kW at 230 V, 25 hp at 220/230 V, 50 hp at 460/480 V, and 60 hp at 575/600 V — spanning the common three-phase motor sizes across North American and IEC voltage systems.

Mounting position is any orientation. The device measures 55 mm wide, 140 mm high, and 149 mm deep — a standard SIRIUS footprint that fits alongside contactors and overload relays on the same DIN rail. Clearance requirements: 50 mm upward and downward, 10 mm to the side, zero forward or backward. No additional clearance is needed at 240 V.

Frequently asked questions

Where can I buy 3RV2332-4KC10?

This part is sourced and quoted to order through independent distribution. Availability and current pricing are confirmed at quote time.

What is the breaking capacity of 3RV2332-4KC10 at 400 V?

50 kA at 400 V AC, with higher ratings at lower voltages (100 kA at 240 V) and lower ratings at higher voltages (8 kA at 500 V, 4 kA at 690 V).
