Silent contactor 230VAC 3NO+1NC 25A AC-7a/b ESC428S

Silent contactor 230VAC – reliable circuit switching

The ESC428S contactor from HAGER is a solid and silent device designed for frequent switching of electrical circuits. It finds application in both home and industrial installations where reliability and long-term operation are required. The contactor's construction based on silent switching technology minimizes acoustic interference, which is particularly important in residential or office spaces.

Characteristics and application

The ESC428S device is characterized by three normally open contacts (3NO) and one normally closed contact (1NC), providing flexibility in circuit configuration. Designed to operate with a control voltage of 230VAC, it allows remote switching of receivers with a maximum current of 25A (AC-7a/b). This makes it ideal for controlling lighting, electric heaters, small motors and other electrical devices. The rated operating voltage of 400V ensures compatibility with most standard electrical installations.

Advantages and benefits

• Silent operation: Silent switching technology reduces noise, increasing user comfort.
• High reliability: Solid construction and high-quality materials guarantee long-lasting and trouble-free operation.
• Versatility: Can be used in various types of installations – home and industrial.
• Flexibility: 3NO+1NC contact configuration allows adaptation to individual needs.
• Safety: IP2X protection degree protects against touching live parts and against the ingress of solid objects with a diameter greater than 12.5 mm.
• High switching capacity: The maximum switching capacity for incandescent lamps is 1900W, and for fluorescent lamps (DUO compensation) as much as 1990VA, allowing control of various receivers.
• Expandability: The ability to add additional equipment allows the contactor to be adapted to specific application requirements.

The mounting depth of 60 mm facilitates the installation of the contactor in electrical distribution boards and control cabinets. This allows installers to quickly and efficiently integrate it with the existing electrical infrastructure. The ESC428S contactor is an optimal solution for people looking for a reliable and silent device for switching electrical circuits.
