2000-4000A FRAME UVTD
A self-priming under-voltage delay release may be provided for special orders
of NXA20~63. There is no external under-voltage delay controller, and the delay time
is 0.35~7.5s, selectable and adjustable with an accuracy of ±15%.
When the under-voltage release is not powered, the circuit breaker cannot be closed either electrically or manually.
