Product information

Description

The Eltako ESR12Z-4DX-UC 4-fold potential-free impulse switch relay with universal control voltage 8-230V UC is designed for modern electrical installations and building automation. This versatile switching device allows for the reliable remote control of multiple independent circuits using potential-free contacts, making it a robust solution for complex distribution boards and lighting control systems.

Advantages

This impulse switch relay offers exceptional flexibility thanks to its wide universal control voltage range, which accommodates various low and high voltage systems without requiring additional adapters. The potential-free contacts ensure galvanic isolation between the control circuit and the switched loads, increasing safety and versatility in system design. Engineered for standard rail mounting, it integrates seamlessly into existing electrical enclosures, providing a reliable and long-lasting performance for professional electrical setups.

Suitable for

  • Building automation and smart home installations
  • Centralized and decentralized lighting control
  • Remote switching of multi-circuit loads
  • Distribution board integration in residential and commercial buildings

When it may not be suitable

This device is not designed for continuous high-frequency switching applications or heavy industrial motor loads that exceed the rated capacity of the relay contacts. It is also not intended for direct outdoor installation without a proper weatherproof enclosure.

Key specifications

  • 4-fold potential-free impulse switch relay
  • Universal control voltage range: 8 to 230V UC
  • Mounting type: DIN-rail mount for distribution boards
  • Designed for electrical switching applications

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations and wiring standards. Mount the unit securely onto a standard DIN-rail inside a suitable distribution enclosure. Connect the universal control voltage lines to the designated control terminals, and wire the circuits to be controlled through the potential-free relay contacts, ensuring that load limits are strictly observed.

What to consider before purchase

  • Verify that the control voltage in your system falls within the 8 to 230V UC range
  • Check that the load requirements match the specifications of the potential-free contacts
  • Ensure sufficient space is available on the DIN-rail within your distribution board
Usage recommendations: Regularly inspect the wiring connections during routine electrical maintenance to ensure secure contact and reliable long-term operation of the relay.
