CSDSC-VFD4 Johnson Controls Current Switch
KKM Solutions is an independent parts distributor, not an authorized Johnson Controls dealer — how we source.
Overview
Part number CSDSC-VFD4 from Johnson Controls, listed in Disconnect Switches. KKM Solutions quotes this part with pricing and availability confirmed per order.
Overview The Johnson Controls CSDSC-VFD4 is a high-performance current switch device designed to provide reliable verification of electrical equipment operation, specifically tailored for variable frequency drive (VFD) applications. Featuring a split-core design, it enables straightforward installation around existing wiring without requiring the disconnection of conductor lines. The unit functions by sensing the current flow induced directly from the power conductor cable, eliminating the need for an external power supply. It provides clear, maintenance-free verification of proof of flow for critical commercial HVAC infrastructure such as fans and pumps. Features Split-core enclosure design allows for simple clamping onto existing lines, eliminating the need to remove or disconnect the conductor. Self-calibrating operation eliminates the requirement for live sensor calibration or adjustment dials, optimizing safety during installation. Integrated command relay functionality combines status sensing and control switching into a single compact device. Large 0.75 in. x 0.75 in. aperture accommodates oversized conductors easily. Induced power mechanism enables the sensor to function completely self-powered directly from the monitored line. Specifications Amperage Range: 1 A to 135 A (minimum 30 Hz), 1.5 A at 20 Hz, 2.5 A at 10 Hz Output Type: Normally Closed (NC) status output Relay Contact Rating: 10 A at 125 VAC Actuation Coil: 12 VDC, 30 mA Status Output Capacity: 1.0 A at 30 VAC/DC Isolation Voltage: 600 VAC rms (UL listed), 300 VAC rms (CE approved) Temperature Range: 5°F to 140°F (-15°C to 60°C) Humidity Range: 0% to 95% non-condensing Aperture Size: 0.75 in. x 0.75 in. (19.1 mm x 19.1 mm) Applications Proof of flow and status monitoring for variable frequency drive (VFD) motor systems. Automation interlocks for commercial fans, exhaust systems, and blowers. Load loss or pump coupling failure detection in hydronic pumping loops. Interfacing high-amperage HVAC equipment status directly to Building Automation Systems (BAS).
