MARS 43066 Relay

The MARS 43066 3PDT 24V Plug Relay is a heavy-duty, general-purpose enclosed switching relay designed for demanding commercial HVACR and industrial control systems. This 3PDT (Three Pole Double Throw) relay features a 24V AC coil with a reliable 13 Amp contact rating at 120 VAC, making it an essential component for managing multi-circuit operations such as fans, blowers, and motor leads. Built with silver alloy, gold-flashed contacts, this unit ensures high conductivity and resists oxidation in harsh environments. The MARS 43066 is housed in a rugged polycarbonate cover to prevent dust and debris contamination, while the 3/16-inch blade terminals provide versatile installation options via plug-in relay mounts, quick-connect terminals, or direct soldering. Its multi-pole configuration is ideal for complex control logic in air conditioning, vending equipment, and custom control panels where compact, reliable switching is critical.

• Versatile Mounting: Compatible with standard octal-style sockets or direct wiring using 3/16" quick-connect/solder terminals.
• Enhanced Durability: Clear polycarbonate housing protects internal components from airborne contaminants and allows for visual inspection.
• High HP Rating: Rated for 1/3 HP at 120V and 1/2 HP at 240V, suitable for small motors and inducer assemblies.
• Reliable Logic Control: 3PDT configuration allows for the simultaneous control of three separate circuits from a single 24VAC signal.
• Industrial Grade Contacts: Silver alloy material with gold flashing ensures consistent electrical performance and longevity.

What is the maximum current rating for the MARS 43066?
This relay is rated for a continuous current of 13 Amps at 120 VAC and is capable of handling inductive loads up to 1/2 HP at 240 VAC.

Can I use this as a replacement for 2-pole relays?
Yes, if the coil voltage matches and the physical mounting space allows, a 3PDT relay can replace SPDT or DPDT relays by utilizing only the necessary poles.

What are the pick-up and drop-out voltages?
The MARS 43066 has a pick-up voltage of 20.4 VAC or less and a drop-out voltage of 7.2 VAC or more, ensuring consistent operation even during minor voltage fluctuations.
