Siemens SENTRON 3VA2225-6HL32-0KH0 — 250 A MCCB, 3-Pole, Line Protection
Its breaking capacity varies by system voltage: 242 kA at 240 VAC, 187 kA at 415 VAC and 440 VAC, 121 kA at 500 VAC, and 4.5 kA at 690 VAC — the 690 V figure is a steep drop, so verify your fault current at that voltage before specifying. The continuous current rating holds at 250 A from 40 °C through 50 °C ambient, then derates linearly to 213 A at 70 °C. A voltage trigger indicator is present; undervoltage release and ground-fault monitoring are not fitted on this order code. No communication function is built in — it is a standalone thermal-magnetic or electronic trip unit (the base switch is 3VA2225-6HL32-0AA0).
Dimensions: 181 mm height, 105 mm width, 86 mm depth. At 105 mm wide, it occupies three standard 35 mm module spaces plus a small margin — confirm clearance against adjacent devices in a crowded enclosure.
