Eaton Z-PU/SS Modular Pushbutton 16A 2NO

The Eaton Z-PU/SS is a high-quality modular pushbutton engineered for precise control within electrical circuits. Designed for seamless integration into standard distribution boards, this device supports manual switching operations with a rated current of 16A. Featuring two normally open (2NO) contacts, it ensures reliable performance in both residential and industrial automation environments, providing a robust solution for controlling lighting, ventilation, or signaling systems.

Advantages

This modular pushbutton stands out due to its compact design, which allows for efficient space utilization on DIN-rail mounting systems. The construction emphasizes durability and ease of installation, making it a preferred choice for professional electrical setups. With its 16A rating and dual normally open contacts, the device offers consistent electrical conductivity and long-term operational reliability, reducing the need for frequent maintenance in demanding control applications.

Suitable for

• Manual control of lighting circuits
• Activation of ventilation or cooling systems
• Integration into industrial automation control panels
• Residential smart home electrical distribution boards
• Manual signaling and alarm triggering

When it may not be suitable

This device is not intended for switching high-power inductive loads directly without appropriate contactors or relays. It is also not suitable for outdoor environments unless housed in a protective enclosure with an appropriate IP rating.

Key specifications

• Rated current: 16A
• Contact configuration: 2 Normally Open (2NO)
• Mounting type: DIN-rail
• Modular width: Standard modular size
• Application: Electrical control circuits

How to use

The Eaton Z-PU/SS is designed for installation on a standard 35mm DIN-rail within a distribution board or control cabinet. Ensure the power supply is disconnected before mounting the device. Snap the unit onto the rail and secure the electrical connections to the terminals according to the wiring diagram. Once installed, the pushbutton provides manual control by pressing the actuator, which closes the two normally open contacts to complete the circuit.

What to consider before purchase

• Verify that the 16A current rating is sufficient for your specific load requirements.
• Ensure the 2NO contact configuration matches your control circuit logic.
• Check the available space on your DIN-rail within the distribution board.
• Confirm that the environment is dry and protected from dust and moisture.

Usage recommendations

Regularly inspect the terminal connections to ensure they remain tight and free from oxidation. Test the pushbutton functionality periodically to ensure smooth mechanical operation and reliable contact closure.
