CSDSC-C50100L0 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C50100L0 is a self-calibrating, solid-state current switch device engineered to detect and monitor electrical current flow in HVAC and building automation systems. Featuring a clamp/split-core design, it provides reliable proof-of-flow and equipment operation verification for fans, pumps, and other motor-driven loads without requiring an external power supply.

Features

• Self-calibrating split-core design for easy installation in tight enclosures.
• Induced loop power eliminates the need for an external power supply.
• Single-turn dial presets motor full load amps, removing the need for live calibration.
• Polarity-insensitive normally open status output.
• LED indication for straightforward diagnostics and status checking.

Specifications

• Amperage Range: 0.50 A to 100 A maximum current.
• Status Output: Normally Open (N.O.), 1.0 A at 30 VAC/VDC.
• Minimum Trip Setpoint: 0.50 A.
• Aperture Size: 0.75 x 0.75 inches (19.1 x 19.1 mm).
• Isolation Voltage: 600 VAC rms (UL), 300 VAC rms (CE).
• Frequency Range: 50/60 Hz.
• Temperature Range: 5 to 140°F (-15 to 60°C).
• Humidity Range: 0 to 95% non-condensing.

Applications

• HVAC fan and pump current verification.
• Building automation and energy management systems.
• Motor run-status confirmation.
• Fault detection and diagnostics in commercial HVAC installations.
