Use UVT time delay controller to prevent the trip of a circuit breaker due to the operation of instantaneous type
UVT when voltage dips occurred instantly on main or control power supply.
� If combining UVT time delay controller and instantaneous type UVT mounted in circuit breaker, it makes a trip
operation after a certain time when its main or control voltage drop below specified value to prevent the
unexpected trip operation caused from instant blackout.
�
It is the outdoor type and can be used by mounting to inside distribution panel or the cradle of circuit breaker.
� It provides control signal (output contact) to indicate the trip status of circuit breaker caused from UVToperation
for indoor type. If control voltage supplied to UVT under normal operation, b contact is conducted and if circuit
breaker is tripped due to UVT operation, a contact is conducted.
