Key Features
1
1. Advanced QuickSafe TechnologyThe OVR T2 3L 15-320 P U features ABB's QuickSafe technology, which ensures that the internal circuit disconnects before the MOVs go into short-circuit. This self-protection mechanism allows for higher-rated backup protection elements, ensuring comprehensive protection against electrical surges.
2
2. High Discharge CurrentsThis surge protective device is designed to handle high discharge currents, with maximum discharge currents ranging from 10 kA to 120 kA, depending on the configuration. This capability ensures robust protection against severe electrical surges.
3
3. Extended Protection LifetimeThe Safety Reserve system with two varistors per line extends the protection lifetime by indicating when one component of the cartridge is damaged, but the protection is still guaranteed. This feature provides advanced warning for maintenance, ensuring continuous operation with degraded protection.
