Silent contactor 24VAC 2NO 25A AC-7a/b ESD225S

Silent contactor for wide application

This reliable silent contactor with 24VAC voltage and 25A current is an ideal solution for both professional installers and end users. Designed to control lighting, heating, ventilation and other circuits, it offers high efficiency and trouble-free operation. Its compact design (only 1 module wide) makes it easy to mount on a DIN rail, saving valuable space in the distribution box.

Construction and operating parameters

The ESD225S contactor is characterized by a two-pole design with two normally open contacts (2NO). It is adapted to work at a rated voltage of 230V AC and a control voltage of 24V AC. It provides high resistance to damage thanks to the rated impulse voltage at the level of 4000V and the insulation voltage of 250V. Thanks to the use category AC-7a/b, it is suitable for frequent switching of circuits. Adapted to work at a temperature from -10°C to 50°C.

Advantages and benefits

• Silent operation: The use of "silent" contactor technology minimizes noise during switching, which is particularly important in residential and office spaces.
• Compact dimensions: A width of only 1 module allows for efficient use of space in the distribution box.
• High reliability: Mechanical endurance of 100,000 cycles and electrical endurance of 30,000 cycles guarantees long-lasting and trouble-free operation of the device.
• Versatility: Suitable for controlling various circuits, such as lighting, heating or ventilation.
• Easy installation: Mounting on a standard DIN rail is simple and quick.
• Safety: Compliance with standards ensures safe operation of the device.
• High switching capacity: The maximum switching capacity for incandescent lamps is as much as 1900W, and for fluorescent lamps – up to 1990 VA (with DUO compensation).
• Wire cross-section: Possibility of connecting flexible wires with a cross-section from 1 to 6 mm² and rigid wires from 1 to 10 mm².

The rated current of the contactor is 25A, it operates at a rated voltage of 230V AC and is controlled by a voltage of 24V AC. It has two normally open contacts (2NO) and occupies one module width. The rated impulse voltage Uimp is 4000V, and the mechanical endurance is 100,000 cycles, and the electrical endurance – 30,000 cycles.

The ESD225S contactor is a solid and functional device that will meet the expectations of even the most demanding users. Its versatility and reliability make it an ideal choice for both new installations and modernization of existing electrical systems.
