CSDSCM-S75050L Johnson Controls Current Switch

Overview

The Johnson Controls CSDSCM-S75050L is a self-calibrating, solid-state current switch designed to provide reliable verification of electrical equipment operation, such as fans and pumps, in commercial and industrial HVAC systems. It features a solid core design and automatically learns a load’s normal operating current to set its own trip threshold without manual adjustments.

Features

• Self-calibrating design eliminates the need for live calibration and manual adjustments
• Solid-state construction with no mechanical contacts ensures long service life and high reliability
• Single-turn dial selects motor full load amps rather than horsepower, reducing required part numbers
• De-energized installation capability improves safety by minimizing the need for personal protective equipment
• Integrated LED indication provides clear visual status of the switch
