Warrick 26B1A0F NC PSH

Optimizing boiler safety and fluid management requires precision components like the Warrick 26B1A0F conductivity liquid level control. This open-board unit is specifically engineered for critical low water cutoff protection, effectively preventing dry firing and potential equipment failure in steam boilers, condensate tanks, and industrial sumps. Operating on a 120V supply voltage with a factory-set 10K Ohm sensitivity, the 26B1A0F provides dependable monitoring for conductive liquids by activating its SPDT powered contacts when the 12 VAC secondary circuit is completed through the sensing probes.

Designed for professional contractors, this solid-state liquid level relay features a direct-acting mode and a 1/16" panel standoff mount for secure integration within existing control cabinets. The N.C. (Normally Closed) configuration, paired with the pushbutton (PSH) reset functionality, ensures that the system stays offline following a low-water event until a manual restart is performed by a technician. This specific model meets CSD1 requirements and is UL 353 recognized as a limit control, offering the rugged reliability needed for high-demand HVACR environments.

• Enhanced Equipment Safety: Designed primarily for boilers and low water cutoff applications to mitigate dry-running risks.
• Streamlined Installation: The 1/16" panel standoff style allows for quick, snap-through mounting on control boards with minimal footprint.
• Intelligent Signal Processing: Includes a built-in time delay to prevent nuisance tripping caused by surface turbulence or wave action.
• Reliable Monitoring: Features an LED indicator for immediate visual status of the relay energized state during troubleshooting.
• Durable Construction: High-quality solid-state components mounted on an open board provide a long mechanical life of up to 5 million operations.

• What liquid types are compatible with 10K Ohm sensitivity? This 10,000 Ohm threshold is ideal for standard tap water and most industrial water applications. For highly treated condensate, always verify liquid resistance to ensure it does not exceed 10K.
• How does the NC PSH (Normally Closed Pushbutton) work? In the event of a low-water trip, the control deactivates. The manual reset button must be depressed to restore operation once the liquid level has returned to the safe operating range.
• Can this relay handle high-current loads? The SPDT contacts are rated for 10 amps resistive at 120/240VAC, making it suitable for direct solenoid control or as a pilot duty signal for larger motor starters.
