Product details

MCCB for line protection with high fault-current capacity

It ships with two auxiliary switches plus a separate trip alarm switch, letting the PLC or BMS know the breaker's state and whether it tripped on fault versus manual open.

Interrupting ratings across voltages

This MCCB's breaking capacity varies by system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V (–). The drop at higher voltages is typical for air-break MCCBs — arc extinction gets harder as voltage rises. For a 480 V panel, you'd use the 440 V figure as a conservative proxy; at 52.5 kA, that still covers most industrial service-entrance scenarios.

That's a shallow derating curve — only 2 A lost over a 30 °C rise — so it's forgiving in a warm enclosure. Maximum power dissipation is 13.1 W, which you'll want to factor into your panel thermal budget if you're stacking several breakers side by side.

The 70 mm depth means it fits in shallow enclosures where a deeper breaker would hit the gland plate. The undervoltage release coil and auxiliary switches are factory-integrated, so no field-assembly of accessories is needed.

Frequently asked questions

How do I get current pricing and availability for 3VA1032-4ED32-0CH0?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ to confirm current pricing and availability at quote time.

Will 3VA1032-4ED32-0CH0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?

No, the 3VA1110-5ED36-0AC0 is a higher-frame 100 A breaker with different dimensions and terminal spacing. The 32 A 3VA1032-4ED32-0CH0 will not physically or electrically drop in without reworking the bus bars and enclosure cutout.

What is the interrupting rating of this MCCB at 240 V?

121 kA at 240 V AC.

What auxiliary switches come with this breaker?

Two auxiliary switches plus one separate trip alarm switch (HQ) are factory-installed.
