Screw terminal, DIN rail, snap-mount socket 27E891 

Offers screw termination for KRPA relays and other devices with 8-pin octal base. This socket is constructed with a spring-loaded latch which allows it to be quickly snapped onto or removed from a DIN or “top hat” style mounting track.  No special tools or extra hardware is required for installation. Sockets have M3.5 screw terminals which accept up to two #12 AWG wires.
