Hager EPN511 Impulse Relay 16A 12V AC 1NO

The Hager EPN511 is a high-quality impulse relay engineered for efficient electrical circuit control in residential, commercial, and industrial environments. This electromechanical component is designed to manage lighting circuits and other electrical loads through momentary pulse signals, providing a reliable solution for modern electrical installations.

Advantages

The primary advantage of the Hager EPN511 is its ability to control lighting from multiple locations using simple push-buttons, which significantly simplifies wiring compared to traditional multi-way switching systems. Its robust construction ensures long-term operational reliability and precise switching performance. The device is designed for easy integration into standard distribution boards, offering a compact and efficient solution for managing electrical loads up to 16A.

Suitable for

• Lighting control systems in hallways and staircases
• Industrial automation and process control
• Building management systems requiring pulse-based switching
• Energy-efficient electrical installations

This relay may not be suitable for applications requiring high-frequency switching or environments where the 12V AC control voltage is unavailable. It is also not intended for use in circuits exceeding its 16A rated current capacity or for applications requiring complex logic functions beyond simple pulse-based switching.

Key specifications

• Rated current: 16A
• Control voltage: 12V AC
• Contact configuration: 1NO (Normally Open)
• Mounting type: DIN rail
• Operational reliability: High-cycle endurance

To use the Hager EPN511, mount the device onto a standard DIN rail within your distribution board. Connect the 12V AC control circuit to the coil terminals and the load circuit to the main contact terminals. When a momentary pulse is sent via a push-button, the relay changes its state, effectively toggling the connected load on or off. Ensure that all electrical connections are tightened securely and comply with local electrical safety regulations.

What to consider before purchase

• Verify that your control circuit provides a 12V AC signal
• Ensure the load current does not exceed 16A
• Check available space on the DIN rail in your distribution board
• Confirm compatibility with your existing push-button wiring configuration

Usage recommendations

For optimal performance and safety, always ensure the relay is installed by a qualified electrician. Periodically inspect the connections to ensure they remain tight and free from oxidation, especially in environments subject to vibration or temperature fluctuations.
