SENTRON 3VA2110-5JP32-0BA0 — 100 A MCCB with Undervoltage Release and Communication
The Siemens SENTRON 3VA2110-5JP32-0BA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels. It carries an undervoltage release (UVR) and a communication function, making it suitable for monitored or remotely controlled feeder circuits.
Breaking Capacity Across Voltages — What the Ratings Mean
This MCCB delivers 187 kA breaking capacity at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V means it is not a primary choice for 690 V line-side protection unless the available fault current is verified below that threshold. At typical 400/415 V distribution levels, 121 kA covers high-fault panels without cascading upstream.
Thermal Performance and Panel Integration
The breaker holds its 100 A rating across the full ambient range from 40 °C to 70 °C — no derating needed for elevated panel temperatures. Power loss is 12.5 W maximum, manageable in a standard enclosure. Dimensions are 86 mm deep, 105 mm wide, 181 mm high; it fits standard Siemens SENTRON mounting footprints and busbar systems.
