Product details

SENTRON 3VA1225-4EF32-0AH0 — 250 A MCCB for Line Protection

Interrupting Ratings Across Voltages

The interrupting capacity varies with system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V.

Above 50 °C, derating applies: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. If the panel ambient exceeds 50 °C, the load must be reduced accordingly.

Auxiliary Switching and Indication

A trip indicator is present.

The 105 mm width is a 3-pole frame size — verify busbar spacing and enclosure cutout against the existing panel layout. The supplied basic switch is order code 3VA12254EF320AA0.
