Klockner-Moeller ZB4-122-KL1 Snap-Fitting Terminal Block

The Klockner-Moeller ZB4-122-KL1 Snap-Fitting Potential Terminal is a twin-level terminal block designed for potential distribution and sensor/actuator wiring in PLC and industrial automation systems, featuring 2 × 11 poles. The snap-fit mounting and twin-level configuration support high-density field wiring for PS4 PLC systems, LE4 local expansion modules, and control panels requiring direct connections of initiators, actuators, and I/O devices. Constructed with an industrial thermoplastic housing, it weighs about 0.15 lb (0.07 kg); the device is discontinued by the manufacturer, with common replacements including Eaton ZB4-110-KL1, Eaton ZB4-102-KS1, and Phoenix Contact PT 2,5-TWIN.
