CSDSC-C50100L1 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C50100L1 is a self-calibrating, split-core current switch 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 reducing installation time. This model includes an integrated normally open command relay to facilitate starting and stopping the monitored load.

Features

• Split-core clamp design fits into tight enclosures without disconnecting wires
• Self-calibrating single-turn dial eliminates live testing and simplifies configuration
• Integrated N.O. command relay provides 10 A at 125 VAC switching power with a 24 VAC/VDC coil
• LED indicators allow easy local tracking of switch and relay status
• Polarity insensitive output simplifies control loop wiring
• Low 0.50 A minimum turn-on extends utility to sub-fractional motors
