6 FAQs about [Reclosing relay capacitor]

What is automatic reclosing relay?

Automatic reclosing relay is designed to initiate multiple reclosures of a circuit breaker which has been tripped by protective relaying. It is essentially a timing device, with a heavy-duty stepping switch operating contacts in response to impulses from a solid-state electronic timing circuit.

How does a reclosing device work?

The reclosing device provides to automatically switch on the protective relay in a sequence of 3 attempts in less than 5 minutes through a quick motor control and a relay system for the system monitoring.

What is MERMEC automatic reclosing relay?

MERMEC automatic reclosing relay is designed to initiate multiple reclosures of a circuit breaker which has been tripped by protective relaying or residual current devices (RCD). It is essentially a timing device, with a heavy-duty stepping switch operating contacts in response to impulses from a solid-state electronic timing circuit.
