The SENTRON 3VA2216-6HK32-0AA0 is a 3-pole molded case circuit breaker rated 160 A continuous (no derating from 40 °C to 70 °C) with an ETU340 electronic trip unit configured for line protection. Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V — figures that cover high-fault industrial mains without needing a current-limiting upstream device. The IP40 front face suits panel-mount applications where the enclosure provides the environmental seal.
Dimensions and panel fit
The breaker measures 105 mm wide by 181 mm tall by 86 mm deep. That 86 mm depth is the dimension to check against your gland-plate clearance or enclosure depth — it's the projection behind the panel face. Width and height match the standard SENTRON 3VA2 frame footprint, so a panel laid out for a 3VA2 breaker accepts this unit without re-drilling the mounting holes.
Trip unit and protection profile
The ETU340 is an electronic trip unit with adjustable long-time, short-time, instantaneous, and ground-fault protection (though this variant ships without ground-fault monitoring). It's the same platform used across the 3VA2 family, so settings and test procedures are consistent if you're standardizing on SENTRON breakers. The 160 A rating holds flat across the full ambient range — no derating needed up to 70 °C, which simplifies panel thermal calculations.
