Fire Pump Control Equipment

Product Overview

The OHK-2XP360F fire protection electrical control device (fire pump controller) is designed to meet the requirements of GB16806-2006 standard for fire protection electrical control devices (fire pump control equipment).  It is used for logic operations, automatic remote signal processing, contactor driving, voltage and current display, and load fault protection switching in fire pump control equipment. It is suitable for direct start, star-delta reduced voltage start, and soft start control cabinets.

Y-Δ Starting: For squirrel-cage asynchronous motors with a delta connection for the stator windings during normal operation, connecting the stator windings in a star configuration during starting and then switching to a delta configuration after starting can reduce the starting current and mitigate its impact on the power grid. This starting method is called star-delta reduced voltage starting, or simply star-delta starting (Y-Δ starting). Recommended application range: Suitable for starting under no-load or light-load conditions, and can be used for motors from 15KW to 55KW.

Product Advantages

● Comprehensive voice guidance, providing real-time voice prompts based on operation, working status, and malfunctions.
