Product details

SENTRON 3VA1220-5MH32-0DH0 — 200 A MCCB with undervoltage release

The interrupting rating drops as voltage rises: 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V. Thermal derating is mild through 50 °C (full 200 A), then steps down: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C.

Panel fit and auxiliary releases

The 3VA1220-5MH32-0DH0 measures 105 mm wide × 158 mm high × 70 mm deep — a standard SENTRON 3VA footprint for 200 A frames. The UVR is wired to the control voltage; if that drops, the breaker trips — common for emergency-stop chains or safety circuits that need a loss-of-voltage trip.
