153H-WJC-49

The Allen Bradley 153H-WJC-49 solid-state controller is engineered for robust performance in industrial settings. Designed as an enclosed combination starter, it adheres to NEMA Type 12 standards, providing protection against dust and industrial contaminants. This controller operates at a rated line voltage of 600 V AC and functions effectively within a frequency range of 50/60 Hz.

With a power rating of 75 horsepower, the 153H-WJC-49 can handle a continuous rated current of 80 amperes. The controller features a control supply supplied by a 120 V AC transformer, ensuring reliable operation in various setups. The initial torque capabilities range from 5% to 90% of the locked rotor torque, allowing for adaptable starting conditions tailored to specific motor applications.

For acceleration, users can set the ramp time between 2 and 30 seconds, ensuring a smooth transition to full speed. Additionally, when full voltage is required, the solid-state controller can perform a direct start in less than a quarter of a second. This device includes a current limit range between 50% and 500% of full-load amperage, providing protective measures and operational flexibility.

In terms of braking, the 153H-WJC-49 provides the ability to support braking currents from 150% to 400% of full-load amperage, making it suitable for demanding applications requiring rapid stopping capabilities. For pump control, the device is configured to manage a start time of 2 to 30 seconds and a stop time ranging from 2 to 120 seconds. Furthermore, equipped with a 3-pole thermal overload relay, the device provides essential overload protection, enhancing safety and operational effectiveness in varied industrial applications.
