Product details

Breaking capacity — what the voltage columns mean for panel coordination

The 3VA1150-4GD42-0AA0: This breaker's interrupting capacity drops as system voltage climbs — that's normal for any MCCB, but the numbers here matter for selectivity studies. At 240 V it clears 121 kA; at 415 V it's 75.6 kA; at 440 V it's 52.5 kA; at 500 V and 690 V it's 11.9 kA. The 50 A continuous rating holds across 40–50 °C ambient; above that it derates smoothly to 45 A at 70 °C.

The 3VA1150-4GD42-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard 4-pole MCCB footprint for DIN-rail or screw-mount panel installation. The TM210 release is fixed-trip, not adjustable, so coordination settings are baked into the breaker selection — no dials to mis-set during commissioning.

Frequently asked questions

What is the breaking capacity of 3VA1150-4GD42-0AA0 at 415 V?

At 415 V AC the interrupting rating is 75.6 kA.

Where can I buy 3VA1150-4GD42-0AA0 and how is it quoted?

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 offer.

Will 3VA1150-4GD42-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0 without rewiring?

Both are 4-pole SENTRON MCCBs in the same 3VA frame family, so the mounting footprint and bus-bar spacing are identical. The 3VA1150-4GD42-0AA0 is rated 50 A versus the lower-current 3VA1110 variants — verify that the panel's bus and cable terminations are sized for 50 A before swapping.
