CSDSC-C50150L2 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C50150L2 is a split-core (clamp) current switch from the Self-Calibrating (CSDSC) Series, designed to provide reliable verification of electrical equipment operation. It uses a single-turn dial to select motor full load amps, allowing the sensor to be safely preset when the panel is de-energized. This eliminates the need for live calibration and personal protective equipment (PPE), significantly reducing installation time in HVAC and building automation applications.

Features

• Split-core design fits easily into tight enclosures without disconnecting the monitored cable.
• Self-powered operation, deriving power directly from the current induced by the monitored line.
• Integrated command relay provides normally open (N.O.) 10 A switching control.
• Adjustable setpoint dial allows simple pre-calibration without live electrical exposure.
• Polarity insensitive status output simplifies field wiring.
• LED indicator provides clear local verification of switch status.
