Silent contactor with manual control capability 24VAC 2NO 25A AC-7a/b ERD225S

Silent contactor with manual control capability – reliability and convenience in one.

This contactor combines functionality, safety and ease of use. Designed to operate at 230V AC, it allows you to control circuits with a current of up to 25A. Equipped with a slider for manual operation, it allows for quick and easy switching of the circuit on and off, even without control power. This solution is ideal for both installers and end users who value control over their electrical installation.

Functionality and application

The ERD225 contactor finds application in a wide range of electrical installations – from domestic to industrial. It is perfect for controlling lighting, heating, ventilation or other electrical devices. Its construction based on AC-7a/b technology ensures reliable operation even with frequent switching cycles and inductive loads. The possibility of manual control is particularly useful during maintenance, repairs or failures of the automation system.

Advantages and characteristic features

• Manual control: The built-in slider allows direct switching of the contactor on and off, which is extremely practical in emergency situations or during service work.
• High switching capacity: Rated current of 25A and the ability to connect loads up to 1900W for incandescent bulbs and 950 VA for fluorescent lamps guarantee a wide range of applications.
• Compact dimensions: A width of only 17.85 mm and a depth of 60 mm allow for easy installation in electrical switchboards with limited space.
• Safety: Protection class IP2X protects against touching live parts.
• Versatility: Designed to operate with a control voltage of 24V AC, making it compatible with most building automation systems.
• Durable construction: Mechanical endurance of 100,000 cycles and electrical endurance of 30,000 cycles ensure long-lasting and trouble-free operation of the device.
• Suitable for different types of loads: The ability to work with fluorescent lamps with DUO compensation (up to 1990 VA) and parallel compensation (up to 810 VA) increases its flexibility.

The ERD225 contactor is characterized by a rated operating voltage of 230V AC and a rated control voltage of 24V AC. Its rated operating current is 25A, and the maximum switching capacity for incandescent bulbs is 1900W. For fluorescent lamps, two values are available: 950 VA and 1990 VA (with DUO compensation). Protection class IP2X provides basic protection against contact.

The ERD225 contactor is a solid and reliable device that will meet the expectations of even the most demanding users. Its functionality, safety and ease of installation make it an ideal choice for both professional installers and individuals who take care of their electrical installation themselves.
