Product Highlights
Description
The Mars M90370 is a single pole double throw relay with a 24 volt coil.
Relay selection involves matching several characteristics, and coil voltage is only the first.
Contact configuration determines what the relay can do: single or double pole, and whether normally open, normally closed, or changeover contacts are provided.
Contact rating determines what it can switch. Ratings are stated for resistive and inductive loads separately, and the inductive rating is the relevant one for motors, contactor coils, and solenoids, since these draw an inrush and produce an arc on opening that resistive loads do not.
Coil voltage and whether the coil is AC or DC must match the control circuit.
Mounting and terminal arrangement must suit the installation, whether the relay plugs into a socket, mounts to a panel, or is fitted with quick disconnect terminals.
Enclosure type matters where the relay is exposed to moisture or contamination.
Substituting on coil voltage and contact count alone, without regard to rating and load type, produces relays that operate initially and fail within months.
Applications include residential and commercial HVAC and refrigeration control circuits.
