Product information

Description

The Legrand undervoltage release for DPX3 circuit breakers is a specialized safety accessory engineered to monitor supply voltage levels in electrical distribution systems. Operating within a range of 200-240V AC/DC, this device ensures that the circuit breaker automatically trips if the voltage falls below the required threshold, thereby preventing potential damage to sensitive equipment and enhancing overall operational safety in industrial and commercial environments.

Advantages

This undervoltage release offers a robust solution for maintaining system integrity by providing an automated response to power fluctuations. By integrating this component into your DPX3 circuit breaker setup, you gain a reliable mechanism that protects connected loads from the risks associated with low-voltage conditions. Its precise design ensures seamless compatibility with the DPX3 series, facilitating straightforward installation and consistent performance in demanding power distribution applications.

Suitable for

  • Industrial power distribution panels
  • Commercial electrical infrastructure
  • Protection of sensitive machinery against voltage drops
  • Emergency shutdown systems

When it may not be suitable

This device is not intended for use with circuit breakers outside of the Legrand DPX3 series. It is also not suitable for applications where the supply voltage consistently falls outside the specified 200-240V AC/DC operating range, as this would lead to unintended or constant tripping of the circuit breaker.

Key specifications

  • Operating voltage: 200-240V AC/DC
  • Compatibility: Legrand DPX3 series circuit breakers
  • Function: Automatic tripping on undervoltage

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The release is designed to be mounted internally within the designated slot of the DPX3 circuit breaker. Ensure the power supply is completely disconnected before attempting to install or service the device. Once correctly seated and wired according to the technical documentation, the unit will automatically monitor the voltage and trigger the breaker mechanism when necessary.

What to consider before purchase

  • Verify compatibility with your specific DPX3 model
  • Ensure the control voltage matches your system requirements
  • Confirm that installation is performed by certified personnel

Usage recommendations

Regularly inspect the electrical system to ensure that the undervoltage release remains free from dust and debris, and perform periodic testing of the tripping function to guarantee continued reliability in your safety infrastructure.
