The 3VA2116-5KP32-0JH0: The interrupting ratings span the common service voltages: 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. That SCCR headroom at 240 V and 415 V covers most industrial secondary-distribution fault-current scenarios without requiring a current-limiting upstream device. The breaker carries a communication function and a shunt trip release (STL) as standard, plus a 2-auxiliary-switch + 1 trip-alarm-switch HQ configuration. The auxiliary switches and shunt trip allow remote status monitoring and emergency tripping without adding external relay logic.
Thermal performance and ambient derating
The continuous current rating holds at 160 A across the full operating ambient range from -25 °C to 70 °C — no derating required up to the maximum. Storage limits span -40 °C to 80 °C. Maximum power loss is 25.5 W at rated load.
