MK3P-I 11-pin 3PDT relay with transparent housing, 10A 250VAC/28VDC rating for industrial control and automation.
The MK3P-I is a widely used general-purpose intermediate relay, designed for industrial control circuits, automation systems, and electrical equipment. With a 3PDT (triple-pole double-throw) configuration and 11-pin octal-style base, it provides reliable multi-circuit switching control.
Key Features:
- 3PDT Configuration: 3 independent pole contacts for complex multi-circuit control.
- 11-Pin Octal Base: Standard pin layout, compatible with common 11-pin relay sockets.
- 10A Contact Capacity: Rated at 10A 250VAC/28VDC, suitable for most control and light-load applications.
- Transparent Housing: Allows visual inspection of contact status and internal components.
- Wiring Diagram Printed: Pinout diagram on the housing for easy installation and wiring.
- Wide Coil Voltage Options: Available in various DC/AC coil voltages to match system requirements.
Applications:
Ideal for motor control, lighting circuits, automation equipment, household appliances, and industrial machinery control.
