Overview

The ABB CA4-31ERT Auxiliary Contact Block (SKU: CA4-31ERT) is a vital accessory for expanding the control and signaling capabilities of ABB EK550 and EK1000 4-pole contactors. Designed for side mounting on either the right or left-hand side of these contactors, this block provides essential auxiliary contacts for control circuits and operational feedback. It features a 2-pole configuration comprising one normally open (N.O.) and one normally closed (N.C.) contact, offering versatile functionality for status indication and interlock circuits. The CA4-31ERT utilizes screw-type connecting terminals that are delivered in an open position, facilitating straightforward and secure wiring. For enhanced operator safety, these terminals are protected against accidental direct contact. Each contact block is clearly marked with its corresponding function, simplifying installation and reducing the potential for wiring errors. This auxiliary contact block is part of ABB's comprehensive range of accessories for motor protection and control, ensuring reliable operation in standard industrial environments. It is specifically compatible with ABB's EK550 and EK1000 4-pole contactors, allowing for flexible system configurations. The CA4-31ERT supports up to 2 poles of auxiliary contacts, making it suitable for applications requiring expanded control and monitoring. Manufactured in Germany (DE), this component adheres to stringent quality standards for industrial automation and control systems.
