CSDSC-C45050L1 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C45050L1 is a self-calibrating current switch device designed to provide reliable verification of electrical equipment operation. It features a clamp-on (split-core) design that allows for installation without disconnecting the monitored cable, and incorporates an integrated command relay. By utilizing a single-turn dial to select motor full load amps, it eliminates the need for live calibration and significantly reduces installation time.

Features

• Self-calibrating design with a single-turn dial to select motor full load amps, removing the need for live calibration.
• Integrated normally open (N.O.) command relay adds switching power without requiring a separate power supply.
• Clamp-on (split-core) housing allows for easy installation in tight enclosures while the panel is de-energized.
• LED indication provides quick visual verification of the switch status.
• Polarity insensitive output simplifies electrical wiring.
