Product details

What this MCCB does — and what the ratings actually mean

That TM240 designation means the thermal trip element is fixed at 32 A — no field-adjustable thermal dial — and the magnetic instantaneous pickup is set at 240 A (7.5x In). For a panel-builder or MRO planner, this is a line-protection breaker, not a motor-protection device; it's sized for cable and busbar protection in distribution panels where you want a fixed thermal curve and no nuisance tripping from inrush. The breaking capacity figures tell the real story for selectivity coordination. At 415 V it's still 75.6 kA, and at 690 V it drops to 11.9 kA. Thermal derating is published across the operating range: it holds full 32 A from 40 °C through 50 °C, then steps down to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.

Built-in auxiliaries and release options

The trip indicator (mechanical flag) and voltage trigger are both present, so you get local visual confirmation of a trip event without needing to read the aux contacts. If your spec calls for any of those, you need a different 3VA suffix — this one is a straightforward line-protection breaker with remote trip capability only.

Dimensions: 130 mm height, 76.2 mm width (3-pole frame), 70 mm depth. The 15 000 latching endurance cycles (mechanical) is typical for a distribution MCCB — not a switching-duty contactor, but fine for the occasional manual disconnect or test operation.

Frequently asked questions

Who supplies 3VA1132-4EF32-0KH0 and how is it quoted for volume purchases?

We source this part through independent distribution channels and quote it to order against an RFQ. Availability and current pricing are confirmed at quote time — no automated stock figures here, just a real quote for your BOM line.

What is the breaking capacity of 3VA1132-4EF32-0KH0 at different voltages?

At 240 V it interrupts 121 kA, at 415 V it is 75.6 kA, at 440 V it is 52.5 kA, and at 690 V it drops to 11.9 kA. These are the published short-circuit ratings for this 32 A frame.

What does the TM240 release mean on this MCCB?

TM240 means a fixed thermal-magnetic release: the thermal element is set for 32 A continuous (non-adjustable), and the magnetic instantaneous pickup is calibrated at 240 A (7.5x In). This is a line-protection breaker, not a motor-protection device with adjustable thermal dial.

What auxiliaries come with 3VA1132-4EF32-0KH0?

It includes a factory-installed shunt trip release (STL), 2 auxiliary switches, and 1 trip alarm switch (HQ configuration). The shunt trip allows remote tripping via a control voltage. There is no undervoltage release, no communication module, and no ground-fault monitoring on this variant.
