CSDSC-C50100L3 Johnson Controls Current Switch

Overview

The Johnson Controls CSDSC-C50100L3 is a self-calibrating current switch device designed to provide reliable verification of electrical equipment operation. It eliminates the need for live calibration by utilizing a single-turn dial to select motor full load amps, which significantly reduces installation time and eliminates the need for live-panel Personal Protective Equipment (PPE). This model features a split-core configuration and an integrated normally open command relay.

Features

• Self-calibrating design utilizing a single-turn dial to select motor full load amps, bypassing the need for live calibration.
• Split-core enclosure enables easy installation around existing wires without disconnecting the electrical load.
• Integrated normally open (N.O.) command relay simplifies wiring and provides local control functionality.
• LED status indicator provides quick visual confirmation of the switch’s on/off state.
• Induced power functionality derives operational energy directly from the monitored conductor cable, eliminating the need for an external power supply.
