Egis Mobile Electric 7422-24 TH3 Dual Relay 2x80A 24V Sealed Relay

The Egis Mobile Electric TH3 Dual Relay (7422-24) is a heavy-duty, sealed dual-output relay designed for 24V marine, vehicle, and powersports electrical systems. Housed in a single compact unit, it delivers two independent 80A continuous outputs, each capable of handling 120A intermittent (5-minute peak) loads — making it an ideal solution for replacing mechanical battery switches, managing battery charging, or switching auxiliary loads.

The TH3 can be connected to an engine ignition signal for simple battery charge management between two batteries, or used for auxiliary load disconnection. It also integrates seamlessly with Egis TH Series Automatic Charging Relays or Time Delay Relays to extend current-carrying capacity or add an additional isolated battery bank.

Key Features:

• Dual 80A Independent Outputs: Two isolated 80A continuous circuits in one housing, each rated for 120A 5-minute intermittent peak
• 24V System Compatible: Operates across a voltage range of 16–34V DC
• Replaces Manual Battery Switches: Reduces battery cable run lengths and associated voltage drop
• Simple & Robust Installation: Includes a sealed MX-150 plug/harness with 2 ft control wires for fast, low-cost installation
• Bullet-Proof Construction: Fully sealed unit built with high-temperature materials — mount anywhere on the vehicle
• Stainless Steel Self-Locking Hardware: 100% non-ferrous, corrosion-resistant attachment hardware
• Integral Diode Suppression: Reduces voltage spikes on control lines during switching
• Single or Dual Split Output Options: Configurable to suit different electrical system layouts
• Fuse Block Compatible: Optional output bus bar enables compact connection to Egis RT or CT fuse block families
