Key ratings and what they mean for your panel
The Siemens SENTRON 3VA1116-4ED42-0BD0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current (Iu) across ambient temperatures from 40 °C up to 70 °C, with only a 10 A derating at the top end — so it holds full capacity in most standard panel environments without upsizing the frame. Its interrupting capacity is what sets this unit apart: 187 kA at 240 V AC, 121 kA at 415 V, and still 76 kA at 440 V. That means it can be used at the main service entrance where fault currents run high, without needing a current-limiting upstream breaker. At 500 V and 690 V the rating settles to 17 kA — still serviceable for most motor branch circuits at those voltages. The TM210 overcurrent release provides thermal-magnetic protection — the thermal element handles overloads, the magnetic element handles short-circuits. No electronic trip unit here, so it's a straightforward, field-reliable choice for line protection where you don't need adjustable curves or communication.
Auxiliaries and releases built in
This breaker ships with an undervoltage release (UVR) factory-fitted, plus three HQ auxiliary switches — that's a lot of auxiliary contact capacity for status feedback or interlocking without adding external relay blocks. The integrated auxiliary trip module is order code 3VA9608-0BB11, so if you need a spare or replacement, that's the part to quote. No ground-fault monitoring, no communication module, no N-conductor protection — this is a clean line-protection build. If your application needs those, you'd step up to the electronic-trip variants in the 3VA family.
Physical fit and environment
Height is 130 mm, width is 4 inches — standard for a 160 A frame MCCB. It mounts on a DIN rail or directly to a backplate. Front face is IP40 rated, so it's fine for general indoor panel use but not washdown areas. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. That covers unheated warehouses and most plant-floor conditions.
