MDR Series mercury displacement relays are designed and built to last even under adverse conditions of temperature, dust and moisture. Capable of rapid on/off cycling, mercury relays can also switch large loads and provide long life, typically operating for millions of cycles. A hermetically sealed steel body houses and protects the contacts. The MDR Series mercury displacement relays are available in all standard coil voltages, and in single-, two- and three-pole arrangements.
