Surge arrester without disconnector ETITEC A 440/10/C-N 002441157

Protection of electrical installations against overvoltage

The ETITEC A 440/10/C-N surge limiter is a protective element that protects the electrical installation from the effects of sudden voltage increases. It is designed for installation in places where there is a risk of overvoltage, such as thunderstorms, lightning strikes, or switching on and off large energy consumers. The lack of a disconnector makes it an ideal solution for applications where visual inspection of the device status after operation is not required.

Characteristics and application

This limiter is characterized by class C, which means that it reacts with a certain delay to short-term current surges. This allows it to cope well with shock loads, such as starting electric motors or transformers. This is particularly important in industrial and commercial installations, where such devices are common. Using a surge limiter increases the reliability and safety of the electrical installation and protects connected devices from damage.

Construction and mounting

The construction of the ETITEC A 440/10/C-N limiter has been designed with easy installation in standard electrical distribution boards in mind. Small dimensions and weight (1g) facilitate its installation even in tight spaces. Manufactured by the renowned manufacturer ETI Polam Sp. z o.o., it guarantees high quality workmanship and reliable operation. The device is manufactured in Poland by ETI Polam Sp. z o.o., which demonstrates compliance with European standards of quality and safety.
