CSDSC-C50150L3 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C50150L3 is a self-calibrating, clamp-on current switch designed to provide reliable verification of electrical equipment operation. By utilizing a single-turn dial to select motor full load amps, it eliminates the need for live calibration and personal protective equipment (PPE) during installation.

Features

• Split-core clamp design that fits easily in tight enclosures.
• Self-powered operation induced directly from the monitored conductor cable.
• Integrated normally open (N.O.) command relay with a 12 VDC coil.
• LED indicators for quick visual switch status verification.
• Polarity insensitive output for simplified wiring.

• Maximum Current: 150 A
• Minimum Trip Setpoint: 0.50 A
• Status Output Rating: Normally Open, 1.0 A at 30 VAC/VDC
• Relay Contact Rating: 10 A at 125 VAC
• Actuation Coil Voltage: 12 VDC, 30 mA
• Frequency Range: 50/60 Hz
• Temperature Range: 5 to 140 degrees F (-15 to 60 degrees C)
• Isolation Voltage: 600 VAC rms (UL), 300 VAC rms (CE)

Applications

Ideal for monitoring small current loads and proving operation for motors driving fans, pumps, blowers, heating coils, and lighting systems in building automation and HVAC applications.
