Legrand Auxiliary Contact 1NO 1NC Side Mount
The Legrand auxiliary contact 66-923002 is a precision-engineered switching device designed for side mounting on compatible circuit breakers and switchgear. This component features one normally open (NO) and one normally closed (NC) contact, providing essential feedback on the operational status of the main electrical device. It is a critical element for modern electrical distribution systems, enabling remote monitoring and automated control in both residential and industrial environments.
This auxiliary contact offers high reliability and seamless integration with Legrand electrical protection equipment. Its side-mount design ensures a compact installation footprint, which is ideal for crowded distribution boards. By providing clear status signaling, it enhances the safety and efficiency of electrical installations, allowing for immediate identification of circuit breaker positions. The robust construction ensures long-term durability and consistent performance under standard operating conditions.
This device is not intended for direct power switching of high-load appliances or motors. It is strictly designed for signaling and control circuits. Furthermore, it is only compatible with specific Legrand circuit breakers and may not fit equipment from other manufacturers.
Installation should be performed by a qualified electrician in accordance with local safety regulations. Ensure the main power supply is disconnected before attempting to attach the auxiliary contact to the circuit breaker. The device clips onto the side of the compatible breaker, and the control wires are connected to the designated terminals. Once installed, verify the switching logic by testing the breaker mechanism to ensure the auxiliary contact correctly reflects the open or closed state.
Always test the auxiliary contact functionality after installation and before putting the electrical system into full operation to ensure accurate status reporting.
