The Siemens SENTRON 3VA2116-6HL32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, with a maximum breaking capacity of 242 kA at 240 V AC. It's built for line protection and includes an undervoltage release (UVR) as standard — meaning it trips if control voltage drops, which is a common requirement for safety circuits or emergency-stop chains in industrial panels.
Breaking capacity and selectivity
The 242 kA at 240 V is the headline number, but the real-world SCCR for a 480 V panel is 187 kA at 415 V and 440 V, and 121 kA at 500 V. At 690 V it drops to 3.7 kA — so this breaker is best suited for low-voltage distribution up to 500 V where high fault current is expected. The 160 A rating holds flat from 40 °C to 70 °C, meaning no derating needed in a warm enclosure.
Panel fit and mounting
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts. The 86 mm depth leaves room for wiring behind the breaker without crowding the gland plate. Rated insulation voltage is 800 V, so it's fine for 480/277 V and 600 V systems.
