EZASHT380AC Shunt trip SHT for EZC100

This release trips the circuit breaker when the control voltage rises above 0.7 x Un.

Control signals can be of the impulse type (≥ 20 ms) or maintained.

Operation

When the circuit breaker has been tripped by an SHT release, it must be reset locally:

• SHT tripping takes priority over manual closing.
• in the presence of a standing trip order, closing of the contacts, even temporary, is not possible.

Circuit breaker tripping by an SHT release meets the requirements of standard IEC 60947-2.
