SENTRON 3VA2216-5MN32-0CL0 — 160 A Motor Protection MCCB
The Siemens 3VA2216-5MN32-0CL0 is a SENTRON molded case circuit breaker (MCCB) designed specifically for motor protection, carrying a continuous current rating of 160 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Rated breaking capacity at 415 V reaches 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V; at 240 V it handles 187 kA. The 3-pole frame includes an undervoltage release (UVR) and a complement of two auxiliary switches plus one trip alarm and one electrical alarm switch (HQ configuration). Phase failure detection is built in, and a trip indicator confirms the breaker has opened on fault. The basic switch core is order code 3VA2216-5MN32-0AA0.
Panel Fit and Thermal Management
The 3VA2216-5MN32-0CL0 occupies a 105 mm wide by 181 mm tall by 86 mm deep footprint — a standard 3-pole MCCB envelope for DIN-rail or screw-mount panel integration. Maximum power dissipation is 22.2 W, which governs the internal enclosure temperature rise and spacing to adjacent devices. Operating ambient range spans -25 °C to 70 °C; storage range extends from -40 °C to 80 °C. The 160 A rating holds flat across the operating band, so no temperature-based derating tables are needed for typical industrial panel conditions.
