The 3VA2225-5JQ32-0CL0: Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V — the 690 V figure is the low end of the curve, so verify it against your fault level if the system runs at that voltage. Current rating holds 250 A up to 50 °C ambient, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. For a panel running at 55 °C, you lose 12 A of headroom — factor that into the load schedule.
Integration and mounting
Dimensions are 105 mm wide, 181 mm high, 86 mm deep. Auxiliary contact configuration includes 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch HQ — enough for remote status indication without an external interface module. An undervoltage release (UVR) is integrated. Communication functions are supported. Ground fault monitoring uses summation current formation on the L-conductor.
