This is a panel-mount breaker for distribution boards and motor control centers where you need high interrupting capacity in a compact footprint. This MCCB carries a 242 kA breaking capacity at 240 V, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 42 kA at 690 V. For a 480 V panel, the relevant figure is the 187 kA at 440 V (the closest published point) — that's well above typical utility fault levels, meaning this breaker handles high-capacity transformer feeds without cascading upstream. The 42 kA at 690 V is relevant for 600 V class industrial systems. That's unusual for a 25 A MCCB; many competitors start derating above 40 °C. Maximum power loss is 0.6 W, negligible for panel thermal budgeting. The 140 mm width for a 4-pole frame is standard for SENTRON 3VA2 breakers — it fits the same DIN-rail or screw-mount footprint as other 3VA2 4-pole units. No end-of-life notice or last-time-buy date is associated with this code. For BOM freeze or PCN watch, this part is stable.","metaTitle":"Siemens 3VA2125-6HK46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2125-6HK46-0AA0 molded case circuit breaker, 25 A, 4-pole, line protection with ETU340 release.
