Product details

It carries a 187 kA interrupting capacity at 240 V AC, dropping to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the curve tells you where this breaker is comfortable and where it isn't. That's unusual for a compact MCCB and simplifies panel thermal budgeting. The 0.6 W maximum power loss keeps heat rise negligible inside a crowded cabinet. This breaker includes ground-fault monitoring via summation current formation on L + N conductors. That's a built-in residual current detection path — no separate RCD module needed for the ground-fault leg. The trip indicator is absent, so fault cause must be read from the breaker position or a downstream annunciator.

Footprint is 140 mm wide × 181 mm tall × 86 mm deep — standard SENTRON 3VA2 form factor for a 4-pole frame.

Frequently asked questions

Where can I buy 3VA2125-5HM46-0AA0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is 3VA2125-5HM46-0AA0's interrupting capacity at 240 V?

187 kA at 240 V AC. At 415/440 V it's 121 kA, at 500 V it's 75.6 kA, and at 690 V it drops to 3.7 kA (–).

Does the 3VA2125-5HM46-0AA0 include ground-fault protection?

Yes, it has ground-fault monitoring via summation current formation on the L + N conductors. This provides residual current detection without a separate module.
