Eaton Z-SB230/SS Impulse Relay 16A 230V AC 2NO

The Eaton Z-SB230/SS is a high-quality 16A impulse relay engineered for reliable switching in 230V AC control circuits. This electromechanical device features two normally open (2NO) contacts, making it an essential component for modern lighting control and automation systems. Designed for seamless integration into residential and commercial electrical installations, it provides a robust and efficient solution for remote switching applications.

Advantages

This impulse relay offers exceptional operational reliability and longevity, ensuring consistent performance in demanding electrical environments. Its design facilitates easy installation on standard DIN-rails, which simplifies the assembly process in distribution boards. By utilizing a bistable switching mechanism, the relay consumes power only during the switching pulse, which contributes to energy efficiency and reduces heat generation within the enclosure.

Suitable for

• Lighting control systems in residential buildings
• Automation of electrical circuits in commercial facilities
• Remote control of lighting groups via push-buttons
• Integration into smart building management systems

When it may not be suitable

This device is not intended for use in DC control circuits or applications requiring a continuous coil voltage supply. It is also not suitable for environments with extreme moisture or high levels of dust without appropriate protective enclosure housing.

Key specifications

• Rated current: 16A
• Control voltage: 230V AC
• Contact configuration: 2 normally open (2NO) contacts
• Mounting type: DIN-rail
• Operating principle: Electromechanical impulse relay

How to use

The Eaton Z-SB230/SS is installed by snapping it onto a standard 35mm DIN-rail within a distribution board. Connect the control circuit to the coil terminals and the load circuit to the 2NO contact terminals. When a momentary electrical pulse is applied to the control input, the relay switches the contacts to the closed position. A subsequent pulse will return the contacts to the open position, allowing for simple remote control of lighting or other loads using momentary push-buttons.

What to consider before purchase

• Ensure the control voltage of your system matches the 230V AC requirement.
• Verify that the total load current does not exceed the 16A rating.
• Check available space on the DIN-rail within your distribution cabinet.
• Confirm that the wiring configuration supports a 2NO contact setup.

Usage recommendations

For optimal performance and safety, ensure that all electrical connections are tightened to the manufacturer's specified torque settings. It is recommended to install the relay in a well-ventilated distribution board to maintain ambient operating temperatures.
