Product Number: 02-021B
The CCL 02-021B is a 24V mini changeover relay with integrated diode protection, designed for reliable switching duties in automotive, commercial vehicle, and heavy-duty electrical systems. Rated at a continuous load of 20A and a peak load of 40A on the closed contact, it is built to handle demanding circuit protection and load-switching applications where voltage spikes must be suppressed at source.
The relay features a normally open contact configuration and is fitted with four 6.3mm blade terminals, providing a secure, industry-standard connection to vehicle wiring harnesses. The integrated diode protection suppresses back-EMF generated by inductive loads such as motors and solenoids, reducing the risk of damage to sensitive control modules. A moulded mounting bracket is incorporated directly into the relay body, enabling quick and clean installation without additional hardware.
With its compact mini form factor, the 02-021B is suited for use in fuse boxes, relay boards, and bespoke wiring installations across a wide range of 24V platforms including trucks, buses, agricultural machinery, and plant equipment. The four-pin layout covers both normally open switching and the common terminal, making circuit integration straightforward for workshop and fleet electrical engineers.
This CCL relay is supplied as a standalone general replacement component. For complementary relay bases, wiring accessories, and related CCL electrical components, please refer to the associated listings on the product page.
