What this MCCB carries and where it fits
The Siemens 3VA2225-8HL32-0JL0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, with a 3-pole configuration designed for line protection. Its breaking capacity reaches 440 kA at 240 V AC and 330 kA at 415 V AC, tapering to 52.5 kA at 690 V AC — a curve that tells you this breaker is built for high-fault industrial distribution, not light commercial panels. The thermal derating is mild: it holds 250 A up to 50 °C, then drops to 241 A at 55 °C and 213 A at 70 °C, so you can size it for a warm enclosure without oversizing the frame.
Auxiliary and release configuration
This variant ships with a shunt trip release (STL) and a full auxiliary switch block: two auxiliary switches plus one trip alarm switch and one electrical alarm switch (HQ designation). The basic switch core is order code 3VA2225-8HL32-0AA0. No undervoltage release, no ground-fault monitoring, no communication module — it's a straight line-protection breaker with remote trip capability via the shunt release.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that mounts on a DIN rail or direct-panel bolted bus. The 86 mm depth is the overall body, not counting handle throw; verify front clearance for the operating mechanism in a shallow enclosure.
