Relè automotive Panasonic ACT112 12 V DC, 20 A normalmente aperto (NO), 10 A normalmente chiuso (NC)

Panasonic ACT112 is an automotive relay for 12 V DC electrical systems. It features a single pole changeover arrangement with one normally open (NO) contact rated at 20 A and one normally closed (NC) contact rated at 10 A. The relay is compact and designed to fit standard relay sockets used in vehicles, providing a dependable switching element for lighting circuits, motors, and vehicle accessories.

Advantages

The relay offers clear separation between NO and NC contacts with defined current ratings, enabling flexible circuit design. Its compact form factor and compatibility with common automotive relay sockets simplify installation and replacement. Build quality and contact ratings support reliable switching under typical automotive load conditions while reducing the need for custom mounting or wiring changes.

Suitable for

• Switching vehicle lighting circuits (headlights, auxiliary lights)
• Controlling small DC motors and actuators
• Powering accessories such as fans, pumps, and audio equipment
• Integration into relay panels or standard automotive fuse/relay boxes

Key specifications

• Coil voltage: 12 V DC
• Contact configuration: one normally open (NO) and one normally closed (NC)
• NO contact current rating: 20 A
• NC contact current rating: 10 A
• Intended application: automotive electrical systems
• Mounting: compatible with standard automotive relay sockets

How to use

Install the relay into a matching automotive relay socket or relay block, ensuring correct orientation of the coil and contact terminals. Connect the control circuit to the coil terminals using appropriate wire gauge and secure power and load connections to the NO and NC contacts according to your wiring diagram. Verify the coil receives 12 V DC when actuated and confirm that loads switch correctly between NO and NC contacts. Inspect terminals for firm connections and provide suitable fusing for the load circuits to protect wiring and contacts.

Recommendations

Use wire gauges and fuses appropriate for the rated currents (20 A for NO, 10 A for NC). Avoid continuous operation at maximum rating without thermal considerations, and inspect contact condition periodically in high-vibration or high-load environments. Ensure the relay is mounted in a location protected from excessive moisture and debris to maintain reliable operation.
