Hager ESC227 Modular Installation Relay 25A 230V AC

The Hager ESC227 modular installation relay is a professional-grade switching device engineered for precise control of electrical circuits in both residential and industrial environments. With a robust design and a rated current capacity of 25 A, this relay ensures reliable performance when managing power distribution for various electrical loads. It operates seamlessly on a 230 V AC supply, providing a stable solution for automated switching tasks within standard distribution boards.

Advantages

This installation relay stands out due to its compact modular design, which occupies only a single module space on a standard DIN rail, allowing for efficient use of space in electrical enclosures. The device is built to high manufacturing standards, ensuring long-term operational reliability and minimal maintenance requirements. Its ability to handle significant current loads makes it a versatile component for modern electrical installations, providing consistent switching performance without the need for manual overrides.

Suitable for

• Lighting control systems in residential and commercial buildings
• Heating and ventilation circuit management
• Automation of electrical distribution networks
• Switching of auxiliary circuits in industrial panels

When it may not be suitable

This relay is not designed for applications requiring manual override functionality, as it lacks a physical switch for local operation. It is also intended strictly for AC voltage systems and should not be used in DC-powered circuits or environments exceeding its specified current rating.

Key specifications

• Rated current: 25 A
• Rated operational voltage: 230 V AC
• Configuration: 1 normally open (NO) and 1 normally closed (NC) contact
• Mounting: DIN rail (1 module width)
• Override: None

How to use

The Hager ESC227 is designed for installation within a standard electrical distribution board. It should be mounted onto a DIN rail by a qualified electrician to ensure safety and compliance with local electrical regulations. Once mounted, the control circuit and the load circuit should be wired according to the terminal markings on the device. Ensure that all connections are tightened securely to prevent overheating or poor contact during operation.

What to consider before purchase

• Verify that the 25 A current rating is sufficient for your specific load requirements
• Ensure the 230 V AC control voltage matches your existing system
• Confirm that the 1NO+1NC contact configuration meets your switching logic needs
• Check available space in your distribution board for a 1-module wide device

Usage recommendations

For optimal longevity and safety, ensure the relay is installed in a well-ventilated enclosure and protected by an appropriate circuit breaker. Periodically inspect the terminal connections to ensure they remain secure over time.
