Honeywell CS-NO-F-50A Switch
The Honeywell CS-NO-F-50A Switch is a high-performance split-core current sensor engineered for precise status monitoring in commercial HVACR and building automation systems. Designed as the direct replacement for H-800, this normally open (N/O) current switch features a versatile sensing range of 0.35A to 200A. The split-core architecture allows for rapid retrofitting on existing conductors without breaking the circuit, significantly reducing labor time on the job site. With a fixed trip point set at 0.35A, it provides reliable HVAC motor status monitoring and proof of flow for fans, pumps, and cooling tower motors. The solid-state output is rated for up to 30VAC/DC, ensuring compatibility with most DDC controllers and PLCs. Built for industrial environments, the CS-NO-F-50A eliminates the need for external power, drawing its operating induction directly from the monitored line for streamlined integration into energy management systems.
Key Benefits for Contractors:
- Retrofit Efficiency: The split-core design allows for installation around 0.35-200A conductors without disconnecting wires or interrupting critical system uptime.
- Precise Low-Current Detection: Engineered to detect current as low as 0.35A, making it suitable for monitoring small fractional horsepower motors.
- Direct H-800 Replacement: Drop-in compatibility ensures zero-config replacement of legacy Honeywell current switches.
- Induction Powered: Self-powered operation reduces wiring complexity and potential failure points within the control cabinet.
- Compact Form Factor: Fits easily into crowded electrical panels and motor starter enclosures.
Common Questions & Technical Specifications:
Does this switch require a separate power supply?
No, the Honeywell CS-NO-F-50A is self-powered via induction from the monitored AC line current.
Can I use this for variable frequency drive (VFD) monitoring?
Yes, it is suitable for monitoring the output side of a VFD, though users should ensure the minimum current threshold is met during low-speed operation.
What is the maximum voltage frequency range for this sensor?
This unit is designed for standard 50/60 Hz AC current monitoring applications.
