Panasonic CB Series Automotive Relay, SPDT, 12V DC, 40A

The Panasonic CB Series Automotive Relay is a high-performance, plug-in relay engineered for demanding 12V DC vehicle electrical systems. Designed for reliability and ease of installation, it handles high-current applications up to 40A with consistent performance. Its robust construction and quality materials ensure dependable switching for critical circuits in a wide range of automotive and vehicle-based scenarios.

This relay utilises a robust silver alloy contact material, providing excellent conductivity and resistance to arcing, which contributes to a long operational life even under frequent switching cycles. The coil is rated for 12V DC operation with a specified resistance of 89.5 ohms, ensuring compatibility with standard vehicle electrical systems. The plug-in mounting style and quick-connect terminals allow for fast, tool-free installation and replacement, minimising downtime during maintenance or upgrades.

Key Features & Applications

• SPDT Configuration: The Single Pole Double Throw (SPDT) contact configuration offers versatile switching options, allowing control of two separate circuits from a single coil input. This makes it ideal for applications like switching between two lights, changing motor direction, or providing a failsafe circuit.
• High Current Capacity: With a robust 40A contact current rating, this relay is perfectly suited for powering heavy-duty loads such as driving lights, winches, cooling fans, fuel pumps, or audio amplifiers.
• Automotive Focus: Specifically designed for the 12V/14V DC environment, it is built to withstand the voltage fluctuations, vibrations, and temperature extremes commonly found in automotive, marine, and off-road vehicle applications.
• Quick-Connect Convenience: The quick-connect terminals simplify wiring, enabling secure connections without the need for soldering, which is perfect for custom installations or repairs in confinedsp.<
