Breaking capacity is the headline: 440 kA at 240 V, 330 kA at 415 V, and still 52.5 kA at 690 V. That puts it in the high-interrupting class — suitable for transformer-fed switchboards where fault currents are severe. The 4-pole width (140 mm) occupies roughly 5.5 inches of rail space; plan your gland plate and wireway clearance accordingly. Power loss is only 0.5 W maximum, so heat buildup in a dense panel is negligible.","metaTitle":"Siemens 3VA2025-8HL42-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2025-8HL42-0AA0 molded case circuit breaker, 25 A rated, 4-pole, ETU320 release, breaking capacity 440 kA at 240 V.
