The Siemens SENTRON 3VA2225-5HL42-0CC0 is a 4-pole molded case circuit breaker rated for 250 A continuous at 40 °C, with a maximum breaking capacity of 187 kA at 240 V. At 250 A continuous, this breaker handles the main feed for a moderate industrial subpanel or a large motor control center feeder. The 4-pole configuration covers three-phase plus neutral, common in North American and IEC distribution.
The 86 mm depth leaves room behind the door for wiring gutters and auxiliary contact access.
Breaking capacity across voltages
This breaker's interrupting performance is rated per voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. For most 480 V or 400 V industrial services, the 121 kA rating is more than enough for a main breaker position.
At 55 °C it derates to 241 A, at 60 °C to 232 A, and at 65 °C to 222 A, hitting 213 A at 70 °C.
Auxiliary and undervoltage release
Factory-fitted with two HQ auxiliary switches and an undervoltage release (UVR). The two auxiliary switches give you status feedback for the PLC or remote monitoring.
