Product details

125 A MCCB with 187 kA interrupting rating — the so-what

The Siemens SENTRON 3VA1112-5ED32-0DH0 is a 3-pole molded case circuit breaker rated for 125 A continuous current at 40 °C ambient, with a maximum interrupting capacity of 187 kA at 240 VAC. At 415 V the rating drops to 121 kA, and at 690 V to 17 kA, which still covers most motor branch circuits on 690 V systems. The thermal derating curve is flat from 40 °C to 50 °C (125 A), then steps down to 114 A at 70 °C — useful to know if this breaker lives in a non-ventilated enclosure near other heat sources.

Panel fit and auxiliary complement

The 3VA1112-5ED32-0DH0 measures 130 mm high × 76.2 mm wide × 70 mm deep — a 3-module-wide footprint that fits the standard SENTRON mounting pattern on a DIN rail or screw-fixed backplate. The trip indicator on the front gives a visible flag when the breaker has opened on a fault, which speeds panel walk-downs.

Frequently asked questions

Where can I buy 3VA1112-5ED32-0DH0 and get a price?

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 price and lead time.

Will 3VA1112-5ED32-0DH0 drop into a panel specified around 3VA1110-5ED36-0AC0 without rewiring?

The 3VA1112-5ED32-0DH0 shares the same SENTRON 3VA frame family and 3-pole footprint, so mechanical fit and bus-bar spacing should be identical. The key difference is the auxiliary switch complement: this unit carries 2 auxiliary switches + 1 trip alarm switch HQ, while the 3VA1110-5ED36-0AC0 may have a different accessory configuration. Verify the auxiliary wiring map against your panel schematic before swapping.

What are the key ratings of 3VA1112-5ED32-0DH0?

Rated 125 A continuous at 40-50 °C, 3-pole, with interrupting capacity of 187 kA at 240 VAC, 121 kA at 415 VAC, 75.6 kA at 440 VAC, and 17 kA at both 500 VAC and 690 VAC. Insulation voltage is 800 V. Maximum power loss is 30.6 W.
