Product details

Breaking capacity — what the voltage-dependent ratings mean for panel coordination

The 3VA1132-3EF42-0AA0: Breaking capacity varies with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Thermal derating and operating envelope

Rated current holds at 32 A from 40 °C through 50 °C ambient, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C.

Dimensions: 130 mm height, 101.6 mm width (4 in), 70 mm depth (2.76 in). Front-face protection is IP40 — suitable for dry indoor panel environments, not washdown areas.

Frequently asked questions

What is the breaking capacity of 3VA1132-3EF42-0AA0 at 415 V?

52.5 kA at 415 V AC. At 240 V it is 75.6 kA, at 440 V it is 32 kA, and at 500 V / 690 V it is 11.9 kA.

What is the rated current of 3VA1132-3EF42-0AA0 at 40 °C?

32 A continuous at 40 °C ambient, holding through 50 °C before derating to 31 A at 55 °C.

Where can I buy 3VA1132-3EF42-0AA0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial response.

What does the TM240 release designation mean on this breaker?

TM240 indicates a thermal-magnetic release where the thermal element is sized for the 32 A frame rating, and the magnetic instantaneous trip threshold is fixed at 240 A.
