Product details

It carries a TM240 thermal-magnetic trip unit, so the thermal element handles sustained overloads and the magnetic element clears fast faults. Rated 32 A continuous at 40 °C ambient, it holds that rating flat through 50 °C before starting a gentle derate: 31 A at 55 °C, 30 A at 70 °C. Breaking capacity is where this breaker earns its panel space: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and still 11.9 kA at 690 V. That's a common requirement for safety circuits where the load must drop if control power fails.

Footprint is 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in).

In a 480 V panel fed from a 150 kVA transformer, the available fault current at the main lug is typically 20–30 kA, so this breaker has 4x headroom. That matters for selective coordination: you can put a 32 A feeder breaker downstream of a larger main and trust the main won't trip on a downstream fault if the time-current curves are properly gapped.

Frequently asked questions

Does 3VA1132-4EF32-0BA0 include an undervoltage release?

Yes, it ships with an undervoltage release (UVR) as part of the basic switch assembly — no field kit required. It's designed for line protection and does not include ground-fault monitoring or communication functions.
