Allen Bradley 140MT-C-KRY



The Allen Bradley 140MT-C-KRY is a padlockable operating knob designed for use with 140MT motor circuit protectors and 140UT circuit breakers. This red and yellow knob enhances safety by allowing you to securely lock the operating mechanism, preventing unauthorized or accidental operation during maintenance or downtime. The 140MT series motor circuit protectors it pairs with are rated for up to 40A and offer reliable short-circuit protection, making them suitable for integration into three-component motor starter setups alongside contactors and overload relays. Distributed by BSP Automation, this accessory helps ensure safe and efficient control of your motor protection devices, especially in installations where coordinated circuit protection and flexibility in conductor sizing are important.
