The MR series is the foundation of the Trinetics product line of multiple relay lighting controls. MR relays feature a time-proven electromagnetic design that provides high compression, low audible noise and minimum eddy current heating. For customers in need of heavy duty construction and long-term performance, the MR series is built for years of trouble-free service in the most challenging environments. This series of air contact relays is offered in the following configurations:

• One or two poles
• Normally open or normally closed
• 30, 60, or 100 amp

Most MR lighting control relays are protected by rugged cast aluminum enclosures, although some of the 30A MR lighting relays may be supplied with heavy duty Bakelite cases.
