The SENTRON 3VA2216-7MS32-0AF0 is a 3-pole molded case circuit breaker (MCCB) in the starter protection version, rated for 160 A continuous current across the full -25 °C to 70 °C operating range. Its interrupting capacity hits 330 kA at 240 V — that is the headline number for fault-clearing at typical North American distribution voltages, so it handles high-fault utility feeds without cascading upstream.
What the interrupting ratings mean for panel coordination
At 415 V and 440 V the breaker interrupts 242 kA; at 500 V it clears 187 kA. Those numbers drop sharply at 690 V to 4.5 kA — a reminder that this MCCB is optimized for 240–500 V distribution, not 690 V motor circuits. The 160 A rating holds steady from 40 °C through 70 °C with no derating, which simplifies panel layout in warm enclosures.
Physical fit and auxiliary contacts
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without gland-plate rework. The breaker ships with one auxiliary switch and one trip alarm switch (HQ type), so you get both status feedback and a separate fault signal without adding a module.
