Product Description
ILC 2R7C 20Amp, SPST, 120/277VAC latching relay
2R7C includes the following:
- Status Contacts: 7= without status
- Connector: C= Molex push-on connector
2R series relays are designed to be the longest lasting,most reliable relays available. By incorporating a unique single moving contact, both endurance and reliability are significantly enhanced. These relays have been tested to handle 200,000 full load cycles and 1,000,000 no load cycles. They have two high quality nickel-silver contacts that can handle
- Single moving contact design
- Made in the USA
- Rated 20 Amps @ 120, 277 and 347VAC
- SCCR rated to 18,000 Symmetrical Amps
- Latching contacts
- Easy mounting with push-on connectors
- Isolated status feedback
