Dettagli

Two-part design comprising a universal base part and an application-specific protection module.

lorem ipsum — Two-part design comprising a universal base part and an application-specific protection module.

Prewired surge arrester unit ITAK EXI BXT 24.

All protection elements are integrated in the plug-in module and are monitored by means of LifeCheck.

The module locking mechanism ensures that the module is vibration-proof and protected against polarity reversal.

BXT ML4 BD EX 24

Space-saving surge arrester module with RFID LifeCheck for protecting two pairs in intrinsically safe measuring circuits and bus systems, meets FISCO requirements. ATEX. Insulation strength > 500 V line-earth.
If LifeCheck detects thermal or electrical overload, the arrester has to be replaced. This status is indicated contactlessly by DEHNrecord LC / SCM / MCM.
