Features:
Modular SPD.
Type 2.
SPD BR-60 is for Imax 60kA.
The core parts are metal oxide vristor components with high discharge capacity.
Supplied with replaceable cartridges and operational indicator.
Remote signaling contact for control device: optional.
Working temperature: -40°C-80°C; Relative humidity: 5%-95%.
Housing protection level (IEC 60529): IP20.
Housing material fram-retarded level (Ul94): UL94-V0.
Application:
Used for AC power line of house, bank, telecom tower and so on.
It’s to provide economical and reliable protection to primary distribution panel boards and power distribution systems.
It’s applied in low-voltage power supply and distribution systems such as computer room equipment, monitoring room equipment, fire control room equipment, telephone room, other low-voltage rooms, offices, and household electrical equipment forpreventing them from indirect lightning strike and surges.
