The Siemens 3VA2225-5JP32-0DL0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current, with an interrupting capacity of 187 kA at 240 V and 121 kA at 415 V. It is a 3-pole unit designed for line protection, fitted with an undervoltage release and a communication function for integration into monitored distribution systems.
What the interrupting ratings mean for your panel
The 187 kA at 240 V is the maximum fault current this MCCB can safely interrupt at that voltage — critical for high-fault-capacity service entrances or industrial feeders where the available fault current exceeds standard 65 kA or 100 kA breakers. At 415 V it still handles 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V. That 690 V figure is low enough that you need to check coordination upstream if your system runs at that voltage. The 250 A continuous rating holds flat from 40 °C through 50 °C ambient — no derating needed in a warm panel. Above 55 °C it steps down: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C. If your enclosure runs hot, size the breaker on the derated figure, not the nameplate.
Lifecycle and sourcing
The breaker ships with a factory-fitted auxiliary switch configuration: 2 auxiliary switches plus 1 trip alarm switch plus 1 electrical alarm switch (HQ type), and an undervoltage release. The communication function is built in, so no separate comm module is needed for basic monitoring.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is the standard 3-pole MCCB footprint for the 3VA2 frame size — it fits the same panel cutout and bus bar spacing as other 3VA2 3-pole units. The 86 mm depth includes the rear terminals; check your gland plate clearance if the panel is shallow. Power loss is rated at 50.5 W maximum at full load. That is moderate for a 250 A frame — plan for ventilation or derating if the breaker is packed tightly with other heat sources in a sealed enclosure.
