Its 4-pole design with line protection suits it for main or feeder protection in distribution panels where ground-fault monitoring via summation current (L + N conductor) is required. The interrupting ratings tell the real story: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — meaning it clears high-fault scenarios at typical industrial voltages without cascading upstream.
The 3VA2025-6HM46-0AA0 measures 86 mm deep, 140 mm wide, and 181 mm high — a compact 4-pole footprint that fits standard panel-mount cutouts for SENTRON MCCBs. No DIN-rail clip; it bolts directly to the mounting plate. The 0.84 W maximum power loss keeps heat dissipation minimal inside the enclosure.
