MK3 11PIN ROUND RELAY

MK3 11-Pin Round Plug-in Relay Heavy-Duty Industrial Control

The MK3 is a high-performance, 11-pin round plug-in relay designed for demanding industrial automation and control systems. Featuring a transparent dust-proof cover and a robust internal mechanism, this relay provides reliable switching for high-current loads and complex logic circuits.

Key Performance Features

• 11-Pin Round Base Configuration: Designed for secure, vibration-resistant mounting into standard 11-pin round relay sockets.

• High Switching Capacity: Capable of handling significant resistive loads, rated for up to 10A at 250VAC or 28VDC, making it suitable for motor control and industrial heaters.

• Transparent Protective Housing: The clear polycarbonate shell allows for easy visual inspection of contact status and internal mechanical health without removing the unit.

• Precision Contact Logic: Features multiple contact sets (3PDT) as indicated by the clear "Bottom View" wiring diagram printed directly on the housing for simplified installation.

• Global Safety Compliance: Proudly displays CE, UL, and CSA certifications, ensuring the component meets rigorous international safety and quality standards.

Technical Specifications

• Base Type: 11-Pin Round Plug-in.

• Contact Rating (Resistive): 10A 250VAC / 28VDC.

• Contact Rating (General): 7A 250VAC.

• Mounting: Requires a standard 11-pin circular socket.

Typical Applications

• Industrial Automation: Control of high-power contactors, solenoid valves, and heavy machinery.

• HVAC Systems: Reliable switching for fans, pumps, and compressors in commercial climate control.

• Panel Building: Essential for logic interlocking and signal multiplication in electrical control panels.

Top 3 Customer Questions & Concerns ‍

 Do I need a specific socket for this relay? Yes. The MK3P-I requires a matching 11-pin round relay base (such as a PF113A) for DIN rail or panel mounting. It cannot be wired directly without a socket.

Can I see if the relay is energized? The clear housing allows you to see the mechanical movement of the armature. Many versions of this series also include a built-in mechanical indicator or LED to show when the coil is active.

 Is this relay suitable for sensitive electronic signals? This relay is optimized for power switching. For very low-current signal switching (dry circuits), you might consider the Omron G5A or G5V series which are designed for smaller loads.
