Hartland Controls 90290 Relay

The Hartland Controls 90290 is a heavy-duty, general-purpose shorting relay engineered specifically for high-demand HVACR and industrial control systems. As a 24V SPNO relay (Single-Pole, Normally Open), this component is a drop-in replacement for a variety of OEM fan relays and power switching applications. The 90290 relay features 0.250-inch quick-connect terminals for rapid field installation and a Class B insulation system designed to withstand the thermal stresses of continuous duty. This Hartland Controls relay utilizes a double-make contact configuration with silver cadmium oxide contacts, ensuring reliable electrical conductivity and arc suppression when switching HVAC fan motors or auxiliary heat kits. Designed for multi-positional mounting, it integrates seamlessly into existing control panels where space is at a premium. This SPNO 24V relay is a reliable solution for technicians needing to restore system logic and motor switching without the overhead of complex lead-wire modifications.

• Universal HVAC Compatibility: Ideally suited for switching fan motors, heating elements, and residential air conditioning control circuits.
• High-Conductivity Contacts: Engineered with silver cadmium oxide contacts to resist pitting and provide a stable electrical connection over extended cycles.
• Streamlined Installation: Standard 1/4-inch quick-connect terminals and a compact footprint allow for efficient replacement in tight service panels.
• Industrial-Grade Build: Features a Class B insulation system to maintain dielectric strength in high-temperature HVAC environments.

What are the primary applications for the Hartland Controls 90290?
Technicians typically utilize the 90290 for air conditioning fan motor switching, furnace blower control, and as a general-purpose pilot duty relay in 24VAC control systems.

Can I use this relay to replace other OEM brands?
Yes, the Hartland Controls 90290 is functionally equivalent to many industry-standard relays, including those from White-Rodgers (90-290Q) and Packard (PR290Q), provided the 24VAC coil and SPNO configuration match.

How does the double-make contact design benefit my installation?
The double-make configuration provides two sets of contacts that close simultaneously, which increases the gap between open contacts to better suppress arcing and improve long-term switching performance.
