What this MCCB is and where it fits
The Siemens SENTRON 3VA2325-5HL32-0HC0 is a 3-pole molded case circuit breaker rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It is designed for line protection in distribution panels and switchboards, with interrupting ratings that scale from 187 kA at 240 V down to 7.5 kA at 690 V, so it handles high-fault utility feeds and downstream sub-distribution alike. Built into a 138 mm wide, 248 mm tall, 110 mm deep frame, it occupies a standard MCCB footprint in a SENTRON panelboard.
Integration notes
Mounts in a standard SENTRON panelboard or standalone enclosure on a DIN rail or direct-mount plate. The 138 mm width fits a 3-pole MCCB cutout; the 110 mm depth leaves clearance for rear-connected busbars. The shunt trip (STL) allows remote tripping from an emergency-stop circuit or a PLC digital output — verify the coil voltage matches the control supply. The two HQ auxiliary switches provide status feedback (open/closed/tripped) to a PLC or indicator lamp. No communication function on this variant; it is a pure power breaker.
