Description
Product Overview
The Dwyer CCS-231150 Current Switch is engineered for high‑performance current detection in demanding industrial settings. Featuring a split‑core sensor, the device offers a non‑intrusive method of measuring current without breaking the circuit, which preserves system integrity and reduces downtime. The adjustable setpoint spans from 0 to 200 A, allowing users to tailor the activation point to specific process requirements. Output is provided as a normally‑open NPN transistor, compatible with a wide range of programmable logic controllers, motor starters, and alarm systems. The housing is constructed from UL‑rated ABS plastic, delivering resistance to impact, chemicals, and temperature extremes while maintaining a lightweight profile. CE and cUL certifications confirm that the switch meets rigorous safety and electromagnetic compatibility standards, making it suitable for global deployment across manufacturing, energy, and automation sectors.

Usage
Designed for versatility, the CCS-231150 excels in applications such as motor protection, transformer monitoring, and load management in conveyor systems. Its split‑core design enables installation on existing conductors without the need for disassembly, simplifying retrofits and new installations alike. The adjustable setpoint can be calibrated to trigger alarms, shut down equipment, or initiate corrective actions when current exceeds predefined thresholds, helping prevent overheating and equipment failure. The NPN normally‑open output integrates seamlessly with PLC inputs, relay coils, and indicator lights, providing clear visual or digital signals to operators. The robust ABS enclosure ensures reliable operation in environments with humidity up to 95 % non‑condensing, dust, and exposure to oil or coolant, making it an ideal choice for factories, processing plants, and utility substations.

FAQ
What does split‑core mean and why is it beneficial?
Split‑core refers to a sensor that can be opened and placed around an existing conductor without disconnecting the circuit. This design simplifies installation, reduces downtime, and maintains system continuity, which is especially valuable in live‑line environments.
How do I set the current activation point?
The switch includes a built‑in potentiometer that allows you to adjust the setpoint from 0 to 200 A. Turn the adjustment screw while monitoring the output signal until the desired activation current is reached.
Is the NPN output compatible with my PLC?
Yes. The NPN normally‑open output can be connected directly to most PLC input modules that accept transistor‑type signals. Ensure the input voltage range matches the PLC specifications for optimal performance.
What environmental conditions can the switch withstand?
The ABS housing is rated for non‑condensing humidity up to 95 %, temperature ranges typical of industrial settings, and resistance to oil, coolant, and dust, making it suitable for a wide variety of harsh environments.
Do you offer calibration services?
Dwyer provides calibration and verification services through its authorized service network. Contact our support team to arrange calibration or to obtain a calibration certificate for compliance documentation.
