The interrupting capacity is the headline figure here: 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V.
The 3VA2025-5JQ36-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The 105 mm width matches the typical 4-module (4 x 27 mm) MCCB form factor, so it drops into existing cutouts or busbar arrangements without rework. Depth of 86 mm leaves room for rear-connected busbars or cable lugs in a shallow backplate gland.
Communication and monitoring
The 3VA2025-5JQ36-0AA0 includes a communication function, which means it can integrate with a building management or energy monitoring system — useful for remote trip indication, load profiling, or selective coordination logging. It does not include an undervoltage release or trip indicator as standard, so if those are required, plan on an accessory module.
