Surge Protection

ED 250 Primary protection

View big image

The ED250 surge protection is designed to protect, against direct and indirect effects of lightning, the low voltage network of an installation. The ED250 is particularly useful in the high keraunic level area where the risk of heavy surge current or even direct strike is high. The ED250 is able to protect a 3 phase (both TNC and TNS) network.

ED 150-275 Primary protection (improved version)

View big image

The ED150 surge protection is designed to protect, against direct and indirect effects of lightning, the low voltage network of an installation. The ED150 is particularly useful in the high keraunic level area where the risk of heavy surge current or even direct strike is high. The ED150 is able to protect a single phase (2 x ED150 in common mode) or a 3 phase (4 or 3 x ED150) network.

ED 50 secondary protection

View big image

ED50 surge protections are used mainly for the secondary protection of single- and three-phase networks on the main electrical switchboard. They provide common-mode protection (between the active conductors and earth) and are available in single-phase and three-phase versions and in a "remote signalling" version (ED50S). The ED50-400 is especially well suited to IT network.

Plugable surge protection for protection of single- and three-phase networks on the main electrical switchboard. The SPD is only 1/2 module (8.5mm) wide per phase, which is the most compact class II SPD on the market. This means 35mm (2 module) for a complete 3-phase protection!

ED210... 1-phase

View big image

ED210 is a secondary surge protector for the single-phase circuits of electrical installations. The "surge protection" function is plugable to make maintenance simple and rapid if there is a disconnection, indicated by the red indicator. The compact ED210 surge protector is installed on the section board and can be coordinated with ED40 or ED150 surge protectors installed on the main electrical panel. This is a new improved type with higher discharge current capability.

Test equipment

View big image

Test equipment for gas discharge tubes, Varistors etc. Exact direct measure of the clamp voltage. Low test current which doesn't "ages" the component. This tester is a portable field version which also can be used for testing transistors, zener diodes etc. up to 1000V. It's guaranteed lower limit is 50V but often can tests be made down to 10V. The batteries is enough for 25000 tests!
