White-Rodgers 90-130 Relay

The White-Rodgers 90-130 Fan Control Center is a heavy-duty DPDT relay and Class II transformer combo engineered for versatile HVAC blower and auxiliary control. Built for high-demand contractor environments, this fan center relay features a multi-tap 120/208/240V primary and a 24V secondary, making it a universal solution for 4x4 junction box mounting. The unit provides 40VA of power and is designed with pre-wired line voltage leads and a low-voltage terminal board for efficient integration into HVAC control systems. Whether you are managing two-speed motors or interfacing with 24V furnace controls, the 90-130 relay ensures reliable inductive switching and inductive load management without unnecessary complexity.

• Universal Compatibility: Multi-voltage primary leads (120/208/240 VAC) reduce the need for carrying multiple single-voltage units on the truck.
• Contractor-Grade Durability: Features an energy-limiting Class II transformer and a rugged DPDT switching mechanism for long-term reliability.
• Streamlined Installation: Color-coded pre-stripped leads and a clearly marked terminal board allow for fast mounting on a standard 4x4 electrical box.
• High Current Capacity: Rated for up to 13.8A at 120VAC, providing robust performance for heavy blower motor applications.

Is the White-Rodgers 90-130 a direct replacement for Mars 24010?

Yes, the 90-130 is a standard industry replacement for the Mars 24010 and other 40VA fan centers sharing the same DPDT relay configuration and technical specifications.

Can I use this relay for both heating and cooling applications?

Absolutely. The double-pole double-throw configuration allows for simultaneous control of different voltage circuits or independent switching of multiple fan speeds in integrated heating and cooling systems.

What mounting configuration is required for this control center?

This unit is designed for standard 4x4 junction box mounting. It can be oriented horizontally, vertically, or at a 90-degree angle to fit tight spaces in commercial or residential equipment.
