Phase sequence and failure relay ckf 316 ff fif

Phase decay sequence and asymmetry sensor for the CKF-316 rail, by F&F. The sensor protects the engine from unwanted decays or voltage drops on individual phases and from changing the phase sequence. The CKF-316 model is dedicated to mounting on a TH-35 modular strip, in the switchboard.

F&F is a Polish manufacturer operating in the electronics industry. Our electrical wholesaler's offer includes, among others, twilight switches, staircase switches, time relays and phase decay sensors. The company's strategy is based on the constant expansion of the offer and occupying attractive market niches.
