Special Series Air Contact Relays

Special Series Air Contact Relays

Special Series Air Contact Relays

Our Special Series air contact lighting relays were derived from purpose-specific custom requirements, but two more standard products resulted: Service Point and Group Lighting.

Service Point I and Service Point II primarily consist of multiple distribution branch circuit breakers protected by a primary disconnect breaker in a panel board configuration. These configurations are used in multicircuit lighting projects by the Department of Transportation and others.

Group lighting control (RLY-CSD) consists primarily of an RLY relay controlling a single-phase Trinetics oil or vacuum switch on the primary side of one or more lighting transformers. This primary-side switching is popular where one control for multiple transformer lighting circuits is required, such as ballpark lighting or other wide area lighting configurations.
