CSDECM-S25050L Johnson Controls Current Switch

Overview

The Johnson Controls CSDECM-S25050L is a solid-core, fixed setpoint current switch device specifically engineered for Electronically Commutated Motors (ECMs) and other electrical loads. It features a low minimum turn-on threshold of 250 mA to prevent false readings caused by the standby current drawn by idle ECMs, ensuring reliable verification of equipment operation.

Features

• Solid-core design with a compact profile that fits easily into tight enclosures
• Induced power from the monitored conductor cable, eliminating the need for an external power supply
• Fixed setpoint avoids the need for manual calibration or settings
• Low turn-on current extends usage to sub-fractional horsepower motors
• Certified to CE and UL standards
