Siemens SENTRON 3VA2225-5HL32-0CH0 — 250 A MCCB for Line Protection
It carries a maximum interrupting capacity of 187 kA at 240 V and 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 4.5 kA at 690 V — the voltage-dependent curve you need to check against your available fault current at the panelboard.
Above that, it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. If your panel runs hot — near a furnace line or in a sealed enclosure — size the load accordingly or plan for forced ventilation. The 86 mm depth leaves clearance for rear-connected busbars in a standard 400 mm deep enclosure.
Auxiliary and Release Configuration
A trip indicator is present on the front face, giving a visual flag when the breaker has tripped on overcurrent or short circuit — no need to probe with a meter to distinguish a trip from a manual OFF. The basic switch (the interrupting core) carries order code 3VA2225-5HL32-0AA0, which is the base breaker without auxiliaries. This variant adds the UVR and switch package on top of that core.
