## Long description

The Hager EPN540 is a professional-grade impulse relay engineered for precise electrical circuit management in both residential and industrial environments. This device operates at a 230V control voltage and supports a 16A current rating, providing a dependable solution for remote switching applications. With its 4 normally open (4NO) contacts, it allows for the simultaneous control of multiple lighting or power circuits from various points using momentary push-buttons.
Advantages
The primary benefit of the Hager EPN540 is its ability to simplify complex wiring configurations by enabling multi-point control of electrical loads. Its robust construction ensures long-term reliability and consistent performance even in demanding power distribution systems. The design focuses on energy efficiency and ease of integration into standard DIN-rail mounting setups, making it a preferred choice for electricians and facility managers seeking a durable switching component.
Suitable for
Lighting control systems in hallways and large rooms
Multi-point switching of electrical appliances
Industrial automation and power distribution panels
Building management systems requiring remote load activation
When it may not be suitable
This impulse relay is not designed for applications requiring continuous high-power motor starting or heavy inductive loads that exceed its 16A rating. It is also not intended for use in DC-only control circuits, as it is specifically optimized for AC voltage operations.
Key specifications
Rated current: 16A
Control voltage: 230V AC
Contact configuration: 4 normally open (4NO)
Mounting type: DIN-rail
Operating voltage range: 250-400V AC
How to use
The Hager EPN540 is designed for installation within a standard electrical distribution board on a DIN rail. Wiring should be performed by a qualified professional in accordance with local electrical codes. Connect the control circuit to the coil terminals and the load circuits to the respective 4NO contact terminals. Once installed, a momentary pulse from a push-button will toggle the relay state, closing the contacts to power the connected load until the next pulse is received.
What to consider before purchase
Ensure the total load current does not exceed 16A
Verify that your control system provides a 230V AC signal
Check available space on the DIN rail within your distribution board
Confirm that the 4NO contact configuration meets your specific circuit requirements
Usage recommendations
For optimal longevity and safety, ensure all terminal connections are tightened to the manufacturer's specified torque settings and verify that the relay is protected by an appropriately rated circuit breaker.
