Warrick 26MB1A0E06 LWCO

The Warrick 26MB1A0E06 is a professional-grade low water cutoff (LWCO) relay designed for precise liquid level control in commercial and industrial boiler applications. Engineered to meet CSD1 requirements, this 120V solid-state controller utilizes conductivity probe sensing to protect equipment from dry-fire conditions. The 10kOhm sensitivity is factory-set to ensure reliable performance across various water qualities, while the 11-pin octal plug-in design allows for rapid field replacement and integrated maintenance. This specific configuration features a 6-second time delay on decreasing levels, effectively filtering out nuisance trips caused by turbulence or surging within the boiler. Rated for a temperature range of -40°F to 150°F, the SPDT powered contacts provide a 10A resistive load capacity, making it a robust solution for primary or secondary boiler safety interlocks. With its Lexan housing and LED status indicator, technicians can quickly verify operation and troubleshoot signal integrity directly at the control panel.

• CSD1 Compliance: Specifically designed to meet safety standards for boiler low water protection.
• Enhanced Stability: Built-in 6-second delay prevents rapid cycling due to water surface agitation.
• Plug-and-Play Installation: 11-pin octal socket interface streamlines mounting and reduces downtime.
• Industrial Durability: Solid-state components housed in clear Lexan for reliable performance in harsh mechanical rooms.
• Visual Diagnostics: Integrated LED provides immediate feedback on relay state and probe connectivity.

Is the 10kOhm sensitivity compatible with my water type?
Standard 10kOhm sensitivity is ideal for most municipal and treated boiler water. For high-purity or ultra-low conductivity fluids, a higher sensitivity module may be required.

Can this relay be used for automatic reset?
Yes, this model supports automatic reset functionality when the liquid level returns to the probe, though it can be configured for manual reset depending on your loop wiring and auxiliary components.

What is the purpose of the 6-second delay?
The delay ensures the burner circuit only trips during a genuine low-water event, ignoring temporary dips caused by steam bubbles or wave action in the sight glass.
