The Eaton Cutler-Hammer BF04F industrial control relay features four normally closed contacts (4 NC) in a single BF device. It is rated for 10 A at up to 300 V AC and uses a coil rated 110/120 V AC. As a 4-pole BF control relay, it is designed for control circuits that require multiple closed paths to be switched by a standard line-voltage coil.
