CSDSC-C45050L3 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C45050L3 is a self-calibrating clamp-on current switch device designed to provide reliable verification of electrical equipment operation. It features a single-turn dial to select motor full load amps, eliminating the need for live calibration and significantly reducing installation time. This device is self-powered, inducing operational power directly from the monitored conductor cable.

Features

• Self-calibrating design that utilizes full load amps instead of horsepower, eliminating line-voltage variations.
• Clamp-on core architecture for simple installation onto existing wiring.
• Integrated normally open (N.O.) command relay offering 10 A at 125 VAC switching capability with a 12 VDC coil.
• LED indicators providing clear visual status of switch operations.
• Presettable sensor that eliminates the need for personal protective equipment (PPE) required for live panel calibration.

Specifications

• Minimum Trip Setpoint: 0.45 A
• Maximum Monitored Current: 50 A
• Status Output Capacity: 1.0 A at 30 VAC/VDC (Normally Open)
• Relay Contact Rating: 10 A at 125 VAC (12 VDC, 30 mA coil)
• Frequency Range: 50/60 Hz
• Operating Temperature: 5 to 140°F (-15 to 60°C)

Applications

• Proof of operation and status monitoring for HVAC fans, blowers, and pumps.
• Integration into building automation systems for mechanical load verification.
• Status tracking for heating coils and lighting systems.
