Overview

The ABB CA4-31NK is a 4-pole auxiliary contact block designed for front mounting, specifically engineered for use with ABB AF09 to AF96 contactors and NF contactor relays. This unit features instantaneous Normally Open (N.O.) and Normally Closed (N.C.) contacts, providing essential control circuit functionality in standard industrial environments. The CA4-31NK utilizes innovative push-in spring terminals, which significantly simplify wiring by eliminating the need for tools. This feature not only reduces installation time but also minimizes the risk of human error during setup. For enhanced safety, these push-in spring terminals are protected against accidental direct contact, ensuring a secure working environment. The terminals support a connection capacity for flexible wires with or without ferrules, ranging from 0.5 mm² up to 2.5 mm² (or 1.5 mm² with insulated ferrules). It also accommodates 1 or 2 x AWG 18 to 14 wires according to UL/CSA standards. The required stripping length is 10 mm, and the degree of protection for the terminals is IP20, compliant with IEC/EN 60947-1 and IEC/EN 60529. A flat Ø 3 mm x 0.5 mm screwdriver is recommended for any necessary adjustments. The CA4-31NK is part of ABB's comprehensive range of auxiliary contact blocks, offering flexible configuration options to meet diverse application requirements in control panels, automation systems, and power distribution units. Its robust construction and clear function markings facilitate quick identification and streamlined maintenance processes. Originating from Germany (DE).
