This specific model features a versatile configuration of 3 Normally Open (NO) and 1 Normally Closed (NC) contacts, making it ideal for complex control circuits, interlocks, and status indication in industrial automation. Engineered for reliability, the CA4-31E attaches directly to the right- and/or left-hand side of compatible ABB contactors, optimizing panel space and simplifying installation. The connecting terminals are of the secure screw type, ensuring a firm and durable electrical connection essential for demanding industrial environments. Delivered in an open state, these terminals facilitate straightforward and efficient wiring. Safety is a key design consideration, with terminals protected against accidental direct contact to safeguard personnel during installation and maintenance. Each terminal is clearly marked with its corresponding function, minimizing the risk of wiring errors and speeding up setup. The CA4-31E is a crucial component for motor starters, control panels, and automation systems requiring additional auxiliary contacts for signaling, feedback, or safety interlocks. Its side-mounting design is particularly advantageous for expanding the functionality of existing contactor installations without requiring significant panel modifications.
