Product information

Description

The Hager ESD425 is a high-performance modular contactor engineered for precise electrical switching within distribution boards. Designed to handle a rated current of 25A, this device operates with a 24V AC control voltage and features a 4NO contact configuration. It provides a robust solution for managing electrical loads in both residential and commercial environments, ensuring consistent performance and long-term reliability in power distribution systems.

Advantages

This modular contactor stands out due to its compact design, which allows for efficient space utilization in standard electrical enclosures. The high-quality construction ensures quiet operation, minimizing noise in sensitive environments. Its reliable switching mechanism is built to withstand frequent operations, providing durability and reducing the need for maintenance in demanding electrical setups.

Suitable for

  • Controlling lighting circuits in commercial buildings
  • Managing heating and cooling systems
  • Operating ventilation equipment
  • General power switching in distribution boards

When it may not be suitable

This device is not intended for use in high-voltage industrial power distribution systems exceeding its rated current capacity. It is also not suitable for environments requiring DC control signals, as it is specifically designed for 24V AC operation.

Key specifications

  • Rated current: 25A
  • Control voltage: 24V AC
  • Contact configuration: 4 Normally Open (4NO)
  • Mounting type: DIN rail

How to use

The Hager ESD425 is designed for installation on a standard DIN rail within a distribution board. Ensure the power supply is disconnected before installation. Connect the control circuit to the A1 and A2 terminals and the load circuit to the main power terminals according to the wiring diagram. Once securely mounted and wired, the contactor will automatically switch the connected load when the 24V AC control signal is applied.

What to consider before purchase

  • Verify that your control system provides a 24V AC signal
  • Ensure the total load current does not exceed 25A
  • Check available space on the DIN rail within your distribution board

Usage recommendations

For optimal performance and safety, ensure all electrical connections are tightened to the manufacturer's specified torque and that the device is installed by a qualified professional in accordance with local electrical regulations.
