  • New condition ensures reliable out-of-box operation

Relay TRV3 24 V 40 A 5-pin gadget

This Vszerda relay switches up to 40 A at 24 V DC using a 5-pin layout. It suits engineers and hobbyists who need a single-pole changeover contact for automotive, industrial or home-automation circuits. The coil operates at 24 V DC and the contacts are rated for 40 A resistive loads.

Practical limits of the 5-pin 40 A interface

The 5-pin footprint fixes the pinout to one coil pair and one changeover contact set, so only a single circuit can be switched per relay. The 40 A rating applies to resistive loads at 24 V DC; inductive or lamp loads will require derating that the datasheet must specify. Coil voltage is fixed at 24 V DC, so 5 V or 12 V logic cannot drive it directly without an additional driver stage.

Questions about this item

Which coil voltage should I choose between the 5 V, 12 V and 24 V versions?

Match the coil voltage to your control circuit; this listing supplies the 24 V coil version, while 5 V and 12 V coils are separate SKUs.

What does the 40 A rating mean when the relay is installed in a vehicle circuit?

The contacts can switch up to 40 A at the rated voltage, so the relay can handle high‑current loads such as starter solenoids or lighting circuits.
