Siemens SENTRON 3VA2116-5JP42-0AA0 — 160 A, 4-Pole MCCB with ETU550
The Siemens 3VA2116-5JP42-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That's a solid 160 A at 70 °C, which means it holds its rating in a hot panel where many breakers start to step down. Four poles, with an ETU550 electronic trip unit. The neutral protection is adjustable — you can set it OFF or anywhere from 20% to 100% of the phase pickup. That's useful for 4-wire systems where you need to coordinate ground-fault or harmonic currents on the neutral. Interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V puts it in the high-fault class — sized for large transformer secondaries or busway feeds where available fault current is substantial.
Panel Fit and Mounting
Footprint is 140 mm wide by 181 mm tall by 86 mm deep. That 86 mm depth is the dimension you check against gland-plate clearance or shallow back-panel enclosures — it's the projection behind the mounting surface. Front face carries an IP40 protection class — fine for a clean indoor panel, but not washdown. The breaker has a communication function, so you can pull trip data and status into a BMS or SCADA system without adding a separate power monitor. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss is 25.5 W — factor that into your panel thermal budget if you're stacking several breakers in a sealed enclosure.
