Contact Protection Relay / E.L.B. contact relay

KR-163/A/...is a universal contact protective relay which transfers an input signal with "NAMUR specification" into the switching signal of a potential-free contact.

KR-163/A/...is approved in combination with our overfill cut-out devices /leak detectors.

KR-163/A/... reports overfull / leak;open circuit and/or short-line fault.
