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. 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.
The integrated auxiliary trip module is order code 3VA9608-0BB11, so if you need a spare or replacement, that's the part to quote. If your application needs those, you'd step up to the electronic-trip variants in the 3VA family.
Height is 130 mm, width is 4 inches — standard for a 160 A frame MCCB. Front face is IP40 rated, so it's fine for general indoor panel use but not washdown areas. That covers unheated warehouses and most plant-floor conditions.
