Product Information
Full details
The Hager EPN510 impulse relay is designed for controlling lighting circuits up to 16A in residential and commercial settings. Its key benefit lies in its reliable switching and manual operation capabilities, allowing for direct control even during power outages. A potential consideration is its specific input voltage requirements, necessitating careful integration into existing systems.

FAQs
What is an impulse relay?
An impulse relay, also known as a latching relay or bistable relay, changes its contact state each time it receives a brief control pulse. It remains in its last state even after the pulse is removed, requiring another pulse to change back.
What is the maximum current the EPN510 can switch?
The Hager EPN510 has a rated switch current of 16A. It can handle a maximum switching current of 16A, even with a lower power factor (cos phi = 0.6).
Can I use the EPN510 for DC control?
Yes, the EPN510 can be controlled by a 110V DC signal, in addition to its standard 230V AC control input.
What does '1 NO contact' mean?
'1 NO contact' means the relay has one contact set that is normally open. This contact set is open (breaks the circuit) when the relay is in its default state and closes (completes the circuit) when the relay is activated by a control pulse.
How do I connect multiple switches to control one light with this relay?
You would connect multiple momentary push buttons in parallel to the control input terminals of the EPN510. Each button press will send a pulse to toggle the relay's state, turning the light on or off.
What is the IP rating of this relay?
The Hager EPN510 has an IP20 protection index. This means it is protected against solid objects greater than 12.5mm (like a finger) but offers no protection against water ingress.
Can I mount auxiliary elements without tools?
Yes, the Hager EPN impulse relays are designed so that auxiliary elements can be easily mounted without the need for tools, simplifying installation and expansion.
Troubleshooting
Relay does not switch when control signal is applied
Verify that the control voltage (230V AC or 110V DC) is correctly applied to the control terminals and matches the relay's specifications. Check wiring connections for tightness and continuity. Ensure the supply voltage is present.
Load does not turn on/off when relay switches
Check the wiring between the relay's output contact and the load. Ensure the load itself is functional. Verify that the rated current of the load does not exceed the relay's 16A switching capacity.
Relay is stuck in one position and does not respond to pulses
Ensure the control signal is a momentary pulse and not a continuous signal. Check for any physical obstruction preventing the internal mechanism from moving. If the issue persists, the relay may need replacement.
Indicator light is not functioning
Confirm that the relay is receiving the correct supply voltage. Check the wiring to the indicator if it's an integrated feature. If the indicator is part of an auxiliary module, check that module's connection and functionality.
Pros and Cons
Pros
- Reliable control of lighting groups up to 16A.
- Manual operation is possible, ensuring control even without power.
- Easy installation with tool-free auxiliary element mounting.
- Clear contact status indication for operational clarity.
- Suitable for both residential and commercial applications.
Cons
- Requires specific input voltage (230V AC, 110V DC).
- Only one normally open contact available.
- IP20 protection rating may require additional enclosure in dusty or wet environments.
- Not suitable for direct control of high-inrush current loads beyond its rating.
Setup, Compatibility & Care
Setup:
- Mounting: Securely mount the EPN510 relay onto a standard 35mm DIN rail. Ensure it is firmly in place.
- Wiring: Connect the control circuit to the appropriate terminals for the 230V AC control voltage. Connect the load to the output terminals (1 NO contact).
- Power Supply: Ensure the supply voltage to the relay (250V AC) matches the rated specifications. Use appropriate wiring gauge (1.5-10mm² for rigid cable, 1-6mm² for flexible cable).
- Auxiliary Elements: If using auxiliary elements (e.g., for enhanced functionality), attach them to the designated slots without tools until they click into place.
Compatibility:
- Control Voltage: Compatible with 230V AC (50-60Hz) and 110V DC control signals.
- Supply Voltage: Operates with a 250V AC supply voltage.
- Switching Current: Suitable for loads up to 16A (with cos phi = 0.6).
- Enclosure: Designed for use within electrical enclosures; IP20 rating means it requires protection from dust and moisture.
Care:
- Cleaning: Disconnect power before cleaning. Use a dry or slightly damp cloth to wipe down the exterior. Avoid using solvents or abrasive cleaners.
- Inspection: Periodically inspect wiring connections for tightness and check for any signs of wear or damage. Ensure ventilation around the relay is not obstructed.
- Environment: Operate within the specified temperature range of -5°C to 40°C. Avoid exposure to excessive humidity or corrosive atmospheres.
