Regarding intrinsic safety, the arrester is considered unearthed and its self-inductance and self-capacitance are negligibly small. The low-impedance arrester design ensures a high impulse current discharge capacity (at least 10x) and a low voltage protection level.
LifeCheck allows quick and easy arrester testing, however, the protection modules may only be read by the hand-held DRC LC reader in non-explosive atmospheres.
Integrated in the protection modules, LifeCheck permanently monitors the operating state of the arrester. Like an early warning system, LifeCheck detects imminent electrical or thermal overload of the protection components. The LifeCheck status can be read in a second by the hand-held DEHNrecord LC reader via non-contact RFID technology. Moreover, the date of the last test of the protection module can be displayed and saved. Stationary installed, a condition monitoring system allows condition-based maintenance of 10 BXT arresters.
The arrester provides protection against vibration effects and shock up to a 30-fold acceleration of gravity. The function-optimised arrester design allows quick and easy replacement of protection modules which house all relevant protection elements.
The protection module and base part must be ordered separately!
