Why Choose the ABB CA5-31NRT Front Mounted Auxiliary Contact Block?
The ABB CA5-31NRT is a reliable 4-pole front mounted auxiliary contact block designed for auxiliary and control circuits in standard industrial environments. As part of ABB's contactor accessory range, it provides additional signalling and control contacts for compatible contactor installations.
The CA5-31NRT provides 3 normally open (N.O.) and 1 normally closed (N.C.) instantaneous contacts. Its front-mounted configuration provides a compact method of expanding the auxiliary contact capacity of a compatible contactor without requiring a separate control relay.
Equipped with screw terminals for connection with ring-tongue ferrules, the CA5-31NRT is designed for secure industrial wiring. The CA5-..N terminal arrangement is intended to match the terminal marking of compatible 4-pole contactors, while ABB order code 1SBN010042R1231 identifies this exact CA5-31NRT configuration.
