152H-WBC-58

The Allen Bradley part number 152H-WBC-58 represents a robust solid-state motor controller ideal for diverse industrial applications. This device is rated for an impressive power output of 350 horsepower and is capable of handling a rated current of 360 amperes. Its integrated fused isolator serves as the disconnect mechanism, providing essential protection for the system.

Enclosed within a NEMA 1 ventilated housing, the unit is designed to facilitate airflow and prevent overheating during operation. Additionally, a 120 V transformer is included for the control supply, ensuring that the system remains powered during operation. To protect against overloads, a 3-pole thermal relay is employed, which helps mitigate potential damage to the motor.

The controller functions effectively at a supply voltage of 600 V AC and operates on a supply frequency of 60 Hz. Notably, it offers an adjustable ramp time of up to 30 seconds, allowing for precise motor speed control during startup and stopping processes. The initial torque range can be configured from 5% to 90% of locked rotor torque, providing flexibility in the application, making it ideal for heavy-duty electrical motors.

Enhanced braking capabilities allow for a braking current that ranges from 150% to 400% of the full load amperage, demonstrating reliability in emergency stop conditions. For managing pump controls, the device permits startup delays between 2 to 30 seconds and stop delays ranging from 2 to 120 seconds, helping in fine-tuning operational cycles. Furthermore, it supports DOL (Direct On Line) starting with a ramp time of under 0.25 seconds, enabling quick activation of the motor. The current limit function can be set from 50% to 500% of full load amperage (FLA) to provide protection during varying operational demands.
