Honeywell CS-NO-F-50A Fixed Solid Core Current Switch 0.25-50A

The Honeywell CS-NO-F-50A is a compact fixed solid core current switch designed for monitoring electrical current in HVAC and building automation applications. This normally open (N/O) current sensor features a fixed trip point at 0.25 amperes with a maximum current rating of 50 amps, making it ideal for low amperage detection in critical systems.

Key Features:

• Fixed trip point at 0.25A eliminates the need for field calibration
• Solid core construction with 0.52-inch sensor aperture
• Compact design measuring 2.27 x 1.60 x 1.04 inches
• Operates on 50/60Hz frequency with induced sensor power
• Temperature rating of -15°C to 60°C for versatile installation environments
• 600V RMS insulation class for safe operation
• Pre-set threshold allows installers to avoid electrical hazards during installation

This current switch is particularly effective for detecting mechanical failures on fans and pumps, monitoring industrial processes, and tracking the operational status of critical motors. The fixed trip point design saves approximately 30 minutes per installation by eliminating the need to return to the job site for calibration. Compatible with optional CR Series command relays for enhanced functionality.
