The Siemens SENTRON 3VA2116-5KP32-0BC0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 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 power distribution.
Breaking capacity across the voltage range
This MCCB delivers 187 kA 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 fault current is tightly bounded; at standard 400/415 V distribution levels the 121 kA rating handles most industrial service-entrance and feeder applications.
Thermal performance and panel integration
The breaker holds its full 160 A rating across the entire operating temperature range from -25 °C to 70 °C with no derating needed. Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA form factor that fits existing panel cutouts and busbar layouts. Maximum power loss is 28 W, manageable for enclosed panel thermal budgets.
