Auxiliary contact blocks are designed for controlling auxiliary and control circuits in standard industrial environments. For front mounting, options include the CA4 series, available in 1 or 4-pole configurations with instantaneous N.O. and N.C. contacts, the CC4 1-pole block featuring an N.O. leading or N.C. lagging contact, and the CAT4 2-pole block with instantaneous N.O. + N.C. contacts, along with an A1/A2 coil terminal connection on the front face. To ensure compliance with standard requirements, the appropriate 4-pole auxiliary contact blocks—CA4-..E, CA4-..M, CA4-..U, or CA4-..N—should be selected based on the specific contactor or contactor relay type. For side mounting, the CAL4 2-pole block, featuring instantaneous N.O. + N.C. contacts, can be clipped onto either the right or left side of the contactors. These auxiliary contact blocks come with screw-type connecting terminals that are delivered open, protected against accidental direct contact, and clearly marked for their respective functions.
