- Description
The Schneider Electric G20-25UVR240AC is an MN undervoltage release common to the GoPact MCCB 200 and GoPact MCCB 250, supplied from a 240 V AC 50/60 Hz control circuit. It opens the breaker once the supply voltage drops below 0.7 times Un, with opening guaranteed below 0.35 times Un, and holds the breaker closed above 0.85 times Un. Maximum response time is 25 ms.

Selection Notes
Fit the G20-25UVR240AC where a GoPact MCCB 200 or 250 must drop out automatically on loss or deep sag of a 240 V AC control supply, which is common on interlocked or safety-chain circuits. The opening band between 0.35 and 0.7 times Un is a possible-but-not-guaranteed zone, so trip-time coordination studies should use the 0.35 Un guaranteed-open threshold, not the 0.7 Un upper limit.
