The Siemens SENTRON 3VA2116-5HN32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, designed for line protection in distribution panels and switchgear. Its interrupting capacity reaches 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is the limiting case for high-voltage low-current applications.
Sizing and thermal performance
The 160 A rating holds flat across the entire ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Maximum power loss is 25.5 W at rated load, which matters for enclosure heat budgeting in a sealed panel. Operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — the 86 mm depth is the dimension that governs clearance behind the panel door or inside a shallow enclosure.
