Eaton Z-TN230/1S1O Installation Relay 20A 1NO 1NC 230V AC

The Eaton Z-TN230/1S1O installation relay is a robust electromechanical switching device engineered for reliable performance in residential and commercial electrical installations. Designed for seamless integration into standard DIN-rail systems, this relay provides efficient control over electrical circuits with a rated current of 20A and a control voltage of 230V AC. Featuring a configuration of one normally open (NO) and one normally closed (NC) contact, it serves as a versatile component for managing power distribution and automation tasks.

Advantages

This installation relay stands out due to its high operational reliability and durable construction, which ensures long-term performance in demanding electrical environments. Its compact design allows for space-saving installation on standard DIN rails, making it an ideal choice for modern distribution boards. The clear contact configuration simplifies wiring and maintenance, while the high-quality materials used in its manufacturing guarantee consistent switching cycles and protection against premature wear.

Suitable for

• Lighting control systems in residential buildings
• Automation of heating and ventilation circuits
• General power distribution in commercial facilities
• Switching electrical loads in industrial control panels

This relay may not be suitable for applications requiring high-frequency switching or environments with extreme vibration, as it is an electromechanical device. It is also not intended for use in circuits exceeding its 20A rated current capacity or for direct control of high-inductive loads without appropriate suppression measures.

Key specifications

• Rated current: 20A
• Control voltage: 230V AC
• Contact configuration: 1 normally open (NO) and 1 normally closed (NC)
• Mounting type: DIN-rail
• Device type: Electromechanical installation relay

To use the Eaton Z-TN230/1S1O, ensure the device is mounted securely onto a standard DIN rail within a protected electrical enclosure. Connect the control circuit to the designated coil terminals and wire the load circuit through the NO and NC contacts according to your specific wiring diagram. Always verify that the supply voltage matches the 230V AC specification before energizing the system to prevent damage to the relay or connected equipment.

What to consider before purchase

• Verify that the 20A current rating is sufficient for your specific load requirements
• Ensure the 230V AC control voltage is compatible with your existing control system
• Check available space on the DIN rail within your distribution board
• Confirm that the 1NO/1NC contact configuration meets your switching logic needs

Usage recommendations

Always ensure that the installation is performed by a qualified electrician in accordance with local electrical safety regulations and standards to ensure safe and reliable operation.
