Product details

What this MCCB is and what it does

The Siemens 3VA2110-5JQ32-0BL0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in industrial power distribution. It's a 3-pole unit rated at 100 A continuous across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel design in warm enclosures. The interrupting ratings tell the real story here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V puts it in the high-fault tier — it clears serious bolted faults upstream without cascading to the main breaker, which is what you need when the transformer is right next to the panel.

Frequently asked questions

How do I get current pricing and availability for 3VA2110-5JQ32-0BL0?

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

What are the key interrupting ratings for this MCCB?

187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — these are the maximum fault currents the breaker can safely interrupt at each voltage level.

What is the continuous current rating and does it derate with temperature?

Rated 100 A continuous from 40 °C through 70 °C — no derating needed across that full ambient range, which simplifies panel design in warm enclosures.

What auxiliary switches and releases come with this breaker?

It includes an undervoltage release (UVR) plus 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type).
