Its interrupting capacity reaches 187 kA at 240 V AC and 121 kA at 415 V AC, which means it can safely clear high-fault currents on the secondary side of a large transformer or at a main service entrance without cascading failure upstream. At 690 V the breaking capacity drops to 4.5 kA — still adequate for most motor-circuit applications at that voltage, but worth checking against the available fault current at the point of installation. ## Current derating — the real-world continuous rating Above that, derating is linear: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. If the panel runs hot — say, adjacent to a drive cabinet or in a non-conditioned enclosure — the 55 °C or 60 °C column is the one that governs the load schedule, not the 40 °C nameplate figure. Factory-fitted with 2 auxiliary switches plus 1 trip alarm switch and 1 electrical alarm switch (HQ type), plus a shunt trip release (STL). No undervoltage release is present, so the breaker will not automatically open on loss of control power; if that function is needed, the 3VA2225-5HN42-0BB0 variant carries it. Dimensions: 181 mm height, 140 mm width, 86 mm depth. The 140 mm width is standard for a 4-pole SENTRON 3VA2 frame, so it occupies the same panel footprint as other 4-pole breakers in the series. Maximum power loss is 48 W — a non-trivial heat load in a sealed enclosure; account for it in the thermal budget rather than relying on free-air convection alone.","metaTitle":"Siemens 3VA2225-5HN42-0JL0 SENTRON MCCB, 250A 4-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0JL0 molded case circuit breaker, 250A continuous, 4-pole, 187kA breaking at 240V.

The key difference is the auxiliary release: the 0JL0 carries a shunt trip (STL) for remote tripping, while the 0BB0 carries an undervoltage release (UVR) that opens on loss of control power. If the panel wiring expects a shunt trip signal, the 0JL0 is a direct mechanical swap; if it relies on undervoltage protection, you would need to rework the control circuit."},{"question":"What compliance documentation does Siemens provide for 3VA2225-5HN42-0JL0?","answer":"As a SENTRON molded case circuit breaker, this part carries UL, CSA, and IEC certifications typical for the series.
