Surge arrester without disconnector ETITEC A 500/5/C-N 002441127

Surge protection in low voltage networks

The ETITEC A 500/5/C-N surge arrester is a reliable element protecting electrical installations from the effects of current surges and atmospheric overvoltages. Designed for installation in overhead lines, it effectively protects devices and ensures uninterrupted power supply. The design without a disconnector makes it ideal for applications where minimizing costs and simplicity of installation are a priority.

Construction and application

This arrester utilizes varistor technology, guaranteeing a quick and effective response to sudden voltage changes. The rated discharge current of 5kA and the ability to withstand short-circuit currents up to 4kA make it a solid protection for various receivers. Protection class C means that these arresters cope well with impulse loads typical of devices with induction motors or transformers. Application in TN networks (including TN-C and TN-S) ensures compatibility with most electrical installations.
