Information close
Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

AC surge arresters are devices used to protect AC-powered installations against atmospheric and switching overvoltages. They protect electrical equipment, switchboards, automation systems, and electronic equipment from sudden voltage surges, minimizing the risk of damage and system interruptions.

Products in this subcategory are designed for a variety of applications – from industrial installations, through commercial networks, to high-voltage power systems. The devices effectively reduce overvoltages in the network, ensuring the safety and continuity of operation of protected devices.

Features and properties of AC surge arresters

  • Effective protection against atmospheric overvoltages and network interference,

  • High resistance to surge currents and short-duration pulses,

  • Durable design resistant to external conditions,

  • Can be installed in switchboards, control cabinets, and on transmission lines,

  • Compliance with applicable safety and quality standards (IEC/EN),

  • Optional status indicators or signaling contacts for operation monitoring Devices.

Applications

AC surge arresters are used in:

  • electrical installations in industrial and commercial buildings,

  • switching stations and automation systems,

  • medium and high voltage power networks,

  • protection of devices sensitive to surges, such as motors, transformers, switches, and disconnectors,

  • transmission and power systems exposed to lightning strikes.

Advantages of Use

  • increased reliability and safety installation,

  • reduced risk of device damage and failure,

  • easy integration with existing infrastructure,

  • long-term protection and minimal maintenance,

  • support for a wide range of voltages and installation types.
