PRODUCT DESCRIPTION
ALLEN BRADLEY 199-LJ1 - Manual Motor Starter / Motor Protection Circuit Breaker
This ALLEN BRADLEY 199-L series device functions as a Manual Motor Starter and Motor Protection Circuit Breaker, integrating motor control and thermal-magnetic overload protection into a single compact unit. It is engineered for direct-on-line starting and protection of three-phase and single-phase AC motors in industrial applications such as material handling, pumping, and HVAC systems, ensuring compliance with motor protection standards. The unit provides both short-circuit and overload protection, eliminating the need for separate fuses or overload relays in many configurations.
