Description

Overview

24V 30A 5 pin relay with diode switches normally open automotive and heavy vehicle circuits through a compact 5 pin relay layout. It suits 24V electrical systems where a control circuit needs to switch a higher-current load. Because the relay uses diode protection, match the terminal polarity before fitting.

Features

• 24V relay with 30A current rating for normally open circuits.
• 5 pin layout suits matching relay bases and connector housings.
• Diode protection helps control coil voltage spike when the relay switches off.
• Blister pack contains one relay for counter sale or workshop replacement.

Specifications and Materials

The 24V 30A 5 pin relay with diode uses a normally open contact arrangement for automotive and heavy vehicle electrical circuits. It carries a 24V coil rating, 30A contact rating, 5 pin configuration and diode protection. Part number: 68040BL. The blister pack contains one relay.

See the official manufacturer product page for the relay family details

Compatibility and Fitment

Match the 24V 30A 5 pin relay with diode against the original relay voltage, contact rating, pin layout and protection type before ordering. Do not swap it into a 12V circuit. Also check the relay base, wiring polarity and terminal condition before energising the circuit.

Compliance and Safety

Inspect the relay base for heat damage, loose terminals or corrosion before replacing the relay. If the circuit has failed repeatedly, test the load side as well, because a relay can fail again when the downstream fault remains. For diode-protected relays, confirm coil polarity before power-up.

Trailer Applications

Heavy trailers, trucks and plant with 24V electrical systems use relays like this for switched auxiliary circuits, lighting feeds, control circuits and equipment power paths. Workshops replace them when the original relay no longer switches cleanly or when the coil protection type must match the existing setup.

Why Choose ICS Trailers

ICS Trailers keeps electrical service parts aligned with heavy trailer, transport and workshop ordering. If you are replacing a relay in a mixed 12V and 24V setup, confirm the system voltage before ordering.
