It is designed for line protection and includes an undervoltage release and a communication function. The interrupting capacity is 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. This is a current-production part, so the failure mode to plan for is not obsolescence but correct coordination with downstream devices to avoid nuisance trips or cascade faults. Above that, derate linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. If your panel internal temperature runs at 55 °C, the breaker's effective continuous current is 238 A — not the nameplate 250 A. That 12 A delta matters when sizing for a non-linear load profile near the top of the trip curve. ## Interrupting capacity by voltage level At 415 V and 440 V it holds 121 kA, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V. For a 480 V panel, the available fault current must be below 75.6 kA to use this breaker without series rating restrictions. That is the number to verify against your utility's transformer impedance and cable length. ## Built-in release and auxiliary switch complement No ground-fault monitoring is included on this version. Depth of 86 mm includes the body but not handle projection; allow clearance for the UVR wiring and communication cable bend radius in the enclosure layout. ## Operating environment and power dissipation The 70 °C upper operating limit matches the top of the derating curve, so the breaker can run at 70 °C but only at 200 A. ## Communication and measurement capability This breaker includes a communication function and an 'other measurement function' — likely current measurement and energy metering via a communication module (the basic switch variant is 3VA2225-5KP32-0AA0, which omits those). For a line protection MCCB, the communication allows remote trip indication, load current monitoring, and integration into a facility energy management system. No ground-fault monitoring is present on this variant.","metaTitle":"Siemens 3VA2225-5KP32-0DC0 SENTRON MCCB, 250A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2225-5KP32-0DC0 molded case circuit breaker, 250A continuous, 3-pole, line protection with undervoltage release and communication.
