Hager EPN520 Impulse Relay 16A 230V AC 2NO

The Hager EPN520 is a professional-grade impulse relay engineered for precise electrical circuit management. Operating at 230V AC with a 16A current capacity, this device utilizes two normally open (2NO) contacts to facilitate reliable switching operations. It serves as a robust solution for modern electrical installations, providing consistent performance in both residential and commercial environments where remote control of lighting or other electrical loads is required.

Advantages

This impulse relay offers significant benefits for electrical system design, primarily through its ability to control lighting circuits from multiple locations using simple push-buttons. The mechanical design ensures long-term durability and quiet operation, making it suitable for noise-sensitive areas. Its compact form factor allows for efficient use of space within standard distribution boards, while the high-quality construction guarantees a long service life even under frequent switching cycles.

Suitable for

• Lighting control systems in residential buildings
• Automation of electrical circuits in commercial offices
• Multi-point switching applications using push-buttons
• Integration into smart building management systems

When it may not be suitable

This device is not designed for direct control of high-inductive loads or motors that exceed its 16A rating. It is also not intended for use in environments with extreme moisture or dust without appropriate protective enclosure housing.

Key specifications

• Rated current: 16A
• Control voltage: 230V AC
• Contact configuration: 2 normally open (2NO)
• Mounting type: DIN rail

How to use

The Hager EPN520 is designed for installation on a standard 35mm DIN rail within an electrical distribution board. Wiring should be performed by a qualified electrician in accordance with local electrical codes. The control circuit is connected to the coil terminals, while the load circuit is wired through the two normally open contacts. Once installed, a momentary pulse from a push-button will toggle the relay state, allowing for convenient control of connected lighting or equipment.

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 16A
• Check available space on the DIN rail within your distribution board

Usage recommendations

For optimal longevity and safety, ensure that all connections are tightened to the manufacturer's specified torque settings and that the device is protected by an appropriate circuit breaker.
