Silent contactor with manual control capability 24V DC 2NO 25A AC-7a/b ERD225SDC

Silent contactor with manual control capability 24V DC

This Hager ERD225 modular contactor is a reliable solution for controlling electrical circuits. Designed for both professional installers and end-users, it combines functionality, safety and ease of use. Its quiet operation and manual control capability make it an ideal choice for a variety of applications.

Characteristics and application

The ERD225 contactor is designed to switch AC circuits with a rated voltage of 230V and a current of 25A. It has two normally open contacts (2NO), allowing control of two independent circuits. The 24V DC control voltage ensures compatibility with a wide range of control systems. The manual control slider allows quick and easy switching of the circuit on/off without the need for an external controller – useful during maintenance or automation failures. The silent design guarantees quiet operation, which is particularly important in residential or office environments.

Advantages and benefits

• Versatility: Manual and remote control capability (24V DC) provides flexibility in system configuration.
• Safety: Provides effective protection of the circuit against overload and short circuit – like most circuit breakers in this class.
• Quiet operation: Lack of noise minimizes acoustic interference, which is important in many applications.
• High switching capacity: Supports both incandescent loads (up to 1900W) and fluorescent loads (up to 950 VA, and with DUO compensation even up to 1990 VA).
• Compact dimensions: An installation depth of only 60 mm makes it easy to mount in switchboards with limited space.
• IP2X protection: Provides basic protection against touching live parts and against the ingress of solid objects larger than 12.5 mm.
• Expandability: Compatible with additional accessories, allowing you to tailor functionality to specific needs.

Construction and mounting

The ERD225 contactor is made of high-quality materials, guaranteeing its durability and reliability. Mounting is done on a standard TH35 (35mm) rail. The simple construction makes installation and maintenance easy. Solid connection terminals ensure a safe and secure connection of the wires.
