What this MCCB delivers
The Siemens SENTRON 3VA2216-6JP32-0KF0 is a 3-pole molded case circuit breaker rated 160 A continuous from 40 °C to 70 °C — no derating across that band, which simplifies panel design in warm enclosures. Breaking capacity hits 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault utility feeds without cascading upstream breakers — a real advantage for main or tie applications where SCCR headroom is tight. Rated minimum 240 A and maximum 1 920 A define the magnetic trip range; the unit ships with a shunt trip release (STL) and one auxiliary switch plus one trip alarm switch HQ, giving the panel builder remote status and emergency trip without adding external relays. Communication function is built in, supporting integration with higher-level monitoring — no separate comm module needed.
Panel fit and environment
Measures 86 mm deep, 105 mm wide, 181 mm tall — a compact footprint for a 160 A MCCB, fitting standard distribution panel cutouts without special adapters. Operating range from -25 °C to 70 °C; storage from -40 °C to 80 °C. Maximum power loss 19.7 W — thermal management straightforward in a ventilated enclosure.
Key specs at a glance
Trip indicator and voltage trigger are standard. No undervoltage release, no ground-fault monitoring — those functions must be added externally if needed. Breaking capacities: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, 4.5 kA at 690 V. The steep drop at 690 V means this breaker is best applied on 400 V class systems for full fault-clearing performance.
