Interrupting capacity is what separates this frame from the smaller 3VA1 series: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and still 7.5 kA at 690 V. That's a high-fault rating — means it handles upstream transformer faults without letting them cascade into the rest of the switchboard. The trip range spans 600 A minimum to 4 000 A maximum, so you've got a wide adjustable band for coordination studies. ## What's wired into this variant That's the HQ configuration — you get status feedback for the breaker position AND the trip event, which matters when a PLC needs to know whether the breaker opened on command or on fault. The basic switch variant underneath is 3VA2340-5JP32-0AA0, so the frame and trip unit are the same; the -0HL0 suffix adds the communication function. That means this breaker can talk to a higher-level system — useful for energy monitoring or remote trip indication without pulling separate control wires back to the panel. No undervoltage release on this build, and no ground-fault monitoring version. If you need UVR or GF protection, you're looking at a different suffix. Dimensions are 248 mm tall, 138 mm wide, 110 mm deep — that's about 9.76 by 5.43 by 4.33 inches. That's a wide enough window for outdoor enclosures in most climates, as long as the cabinet isn't sitting in direct sun in Phoenix in July. We source this against an RFQ through our independent distribution network.","metaTitle":"Siemens 3VA2340-5JP32-0HL0 SENTRON MCCB, 400A, 3-Pole","metaDescription":"Siemens 3VA2340-5JP32-0HL0 SENTRON molded case circuit breaker, 400A continuous, 3-pole, 187kA at 240V.
