The 3VA2225-5HN32-0JL0: The 187 kA interrupting rating at 240 V drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 4.5 kA at 690 V. For 690 V applications, the 4.5 kA limit restricts it to low-fault locations or downstream of a current-limiting device.
Thermal derating and continuous current
The breaker holds 250 A from 40 °C through 50 °C (–), then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C (–). The maximum power loss is 48 W, which contributes to the internal temperature rise.
Auxiliary and release configuration
The trip indicator and voltage trigger are both present, meaning remote status and shunt-trip control are built in — no separate accessory kit needed for basic remote tripping and status feedback.
The width is the critical dimension for multi-breaker panel layouts — 105 mm per pole set means a 3-pole unit occupies roughly 105 mm of DIN-rail or mounting-plate width. Verify the busbar or line-side connection spacing matches the terminal centers before committing the panel layout.
