BR-50GR series are Type 1 surge protective devices designed to discharge high current surges without any damage to the back-up electrical equipment.
Εφαρμογή:
• Used in the lightning protection zones concept at boundary LPZ0B-LPZ1.
• For protecting low-voltage consumer’s installations against indirect lightning discharges.
• Protect electrical and electronic equipment against transients, originating from lightning, switching of transformers, lighting, and motors.
Εγκατάσταση:
Better to under the guidance of professional electrician.
Green tab, normal work status, Red tab, failure status, need to be replaced rapidly.
