ABB SACE Tmax XT / Emax / Emax 2 Time Delay Device For Undervoltage Release UVD Series
Brand :
ABB
Caution
Product Description
The undervoltage release can be combined with an electronic time-delay device for the circuit-breaker, allowing for delayed external tripping with adjustable preset times.
Use of the delayed undervoltage trip unit is recommended to prevent tripping when the power supply network for the trip unit is subject to brief voltage drops or power supply failures.
Circuit-breaker closing is inhibited when the UVD is not powered.
The time-delay device must be used with an undervoltage release with the same voltage.
