Relay protection is waterproof and moisture-proof
Home / Relay protection is waterproof and moisture-proof
Unlike standard relays, sealed relays are encased in a protective housing that prevents dust, moisture, and other contaminants from entering. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. A waterproof relay, also called a sealed relay, marine relay, IP67 relay or weatherproof relay, is an electromechanical switch designed to operate reliably in damp, wet or salt-air environments where a standard open relay would corrode, arc or fail prematurely. nted wired boards (PWBs) can be exposed to a variety of harsh conditions during the lifetime of the protection relay.
