UVTSA450-4SWRFSU05 Undervoltage trip.AC100-120/200-240/380-450V, TD, 4pole, NF/DSN400AF,630AF
The undervoltage tripping device UVT trips the breaker automatically when the voltage drops. The tripping voltage is 35% to 70% of the rated voltage. When the voltage recovers to 85% of the rated voltage or above, the UVT can be reset and the breaker closed.
The UVT is mounted on the right side of the breaker and equipped with lead-wire terminal block SLT as standard. Please specify, if left-side mounted type or type with flying leads is needed.
Please consider, the undervoltage trip UVT for 3-pole and 4-pole breaker is different inthe length of wires based on the outline dimen sion of the breaker.
