Breaking capacity runs 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. At 690 V the 4.5 kA figure is lower — this breaker is not your first pick for 690 V high-fault applications, but it still clears moderate faults at that voltage. No ground-fault monitoring version here — that's a separate variant if you need GFCI. Power loss is 50.5 W maximum at rated load. ## What the basic switch and releases tell you Trip indicator is present, so you get a visual flag on the breaker face after a fault. Communication function and 'other measurement function' are listed — this variant supports remote monitoring or control integration, though the exact protocol (PROFIBUS, PROFINET, Modbus) isn't specified here. If you need that detail, the full datasheet covers the communication module options.","metaTitle":"Siemens 3VA2225-5KP32-0BL0 SENTRON MCCB, 250 A, 3-Pole, Line","metaDescription":"Siemens 3VA2225-5KP32-0BL0 SENTRON MCCB, 250 A continuous, 3-pole, 187 kA at 240 V.
