220V AC 11-Pin 3-Pole Electromagnetic Relay – 10A with LED Indicator
The 220V AC 11-Pin 3-Pole Electromagnetic Relay is designed for electrical switching, industrial automation, control panels, and power management applications.
Featuring a 220–230V AC coil, three changeover contacts, and a built-in LED status indicator, this plug-in relay provides reliable switching for compatible electrical circuits.
Its transparent housing allows easy visual inspection of the internal components, while the standard 11-pin connection makes installation and replacement convenient when used with a compatible relay socket.

Connection and Operation
The relay operates using an AC-powered electromagnetic coil.
- Connect the rated AC voltage to the relay coil terminals.
- When the coil is energized, the relay changes the state of its three contact sets.
- Normally Open (NO) contacts close, while Normally Closed (NC) contacts open.
- The built-in LED indicator illuminates when the coil is energized.
- When coil power is removed, the contacts return to their normal positions.

Important Notes
-
This relay uses a 220–230V AC coil, not a 12V or 24V DC coil.
- Use a compatible 11-pin relay socket.
- Never exceed the specified contact ratings.
- Contact current ratings may be lower for inductive loads such as motors and solenoids.
- Mains-voltage installation must be performed by a qualified person.
- Disconnect power before installation or maintenance.
- Confirm the coil voltage and terminal arrangement before connecting the relay.
