Swift Kompany 7421-24 TH3 Relay 160 Amp 24V Battery Relay

The Swift Kompany 7421-24 is a 160 amp, 24V DC sealed battery relay (TH3 series). It replaces a manual battery switch with an electrical relay placed in line between a battery and its electrical loads. That shortens battery cable runs and reduces voltage drop. It suits marine, RV, and commercial vehicle 24V electrical systems.

Key Features:

• 160 amp, 24V DC rating for high-current battery switching
• Replaces manual battery switches, which reduces cable length and voltage drop
• Charge management support: connect to an engine ignition signal to manage charging between two batteries or to disconnect auxiliary loads
• Expandable: works with TH Series automatic charging relays or time delay relays to provide an extra isolated or switched output, or to increase current-carrying capability
• Simple installation: sealed MX-150 plug and harness with 2 ft control wires
• Sealed, high-temperature construction allows mounting almost anywhere on the vehicle or vessel
• Integral diode suppression reduces voltage spikes on control lines during switching
• Stainless steel self-locking hardware
• Single or dual split output options for different electrical system requirements
• An optional output bus bar connects to RT or CT series fuse blocks

A durable, compact relay for battery isolation, auxiliary load control, and simple charge management in 24V systems.
