Surge protector with disconnector ETITEC A 500/10/A-NO 002441160

Electrical installation protection with ETITEC limiters

The ETITEC A 500/10/A-NO surge protector with disconnector is a key element in protecting electrical installations from the effects of lightning strikes and overvoltages occurring during device operation. The device is intended for use in LV networks, both in building installations and on overhead lines. Its task is to quickly discharge excess energy to ground, protecting sensitive components from damage.

The surge protector design is based on disconnector technology, which means that after activation, the device signals a failure and requires replacement. This design ensures reliable operation and allows for quick identification of the damaged element. Protector class A indicates its intended use for protection against switching surges.

Construction and mounting

The ETITEC A 500/10/A-NO surge protector is designed for direct mounting on a TH-35mm DIN rail. Compact dimensions make installation easy even in tight switchboards. The device is characterized by high quality workmanship, which guarantees long-lasting and trouble-free operation. Manufactured by the Polish manufacturer ETI Polam, these surge protectors are valued for their solidity and compliance with applicable standards.

The rated discharge current of 40 kA (peak value) testifies to its high effectiveness in dissipating energy during a surge. The maximum permissible operating voltage is 500 V, making it suitable for most standard LV installations. Optical signaling informs about the operation of the surge protector, facilitating diagnostics and problem localization in the event of a failure.
