152H-WJC-49

The Allen Bradley model 152H-WJC-49 is a solid-state soft starter capable of handling rated line voltages of up to 600 volts AC. This component is engineered for three-phase systems and offers a continuous current rating of 80 Amperes. It provides flexibility in operation through features such as a soft stop time ranging from 2 to 60 seconds. Additionally, slow speed levels can be achieved at either 7% or 15%, allowing customized performance characteristics tailored to specific applications.

The soft starter can limit current within a range of 50% to 500% of the full load amperage (FLA), ensuring effective control during start-up conditions. For those instances requiring immediate power, the device offers a full voltage start ramping in less than 0.25 seconds. It also includes a braking range of 150% to 400% FLA, which can be crucial for certain operational requirements.

In terms of torque management, initial torque levels can be set from 5% to 90% of the locked rotor torque (LRT), enabling efficient handling of load variations during startup. Furthermore, the kickstart boost feature can provide up to 550% of FLA, offering a powerful initial surge when necessary. The enclosure is rated NEMA 12, ensuring protection against dust and incidental contact, which contributes to the longevity and reliability of the device in industrial settings. Control input is provided at 120 volts AC, making it straightforward to integrate into existing systems.
