Breaking capacity is the headline here: 121 kA at 240 V AC, 76 kA at 415 V and 440 V, 53 kA at 500 V, and 3 kA at 690 V. At 415 V, 76 kA covers most industrial transformer secondary faults. The optional motor drive (listed as an available extension) allows remote closing/opening for automated transfer schemes. No communication module onboard, so any remote monitoring needs a separate I/O interface.","metaTitle":"Siemens 3VA2025-4HL32-0AA0 SENTRON MCCB, 25 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA2025-4HL32-0AA0 molded case circuit breaker, 25 A continuous, ETU320 electronic trip, 3-pole.
