Features:
– Class II / Type 2 surge protection device.
– Available with nominal / maximum discharge current 50kA/110kA
– The core parts are metal oxide varistor components with high discharge capacity.
– Excellent performance and favorable price
– Low residual voltage and quick response.
– This surge protective device is used for lightning and overvoltage protection in AC50/60Hz.
– Reliable control
– BR-110 series surge protector devices (SPD) are the best products to protect the low voltage power network from lightning or surge over voltage.
– Fault indication via red mark in the inspection window.
Application:
• For using in the lightning protection zones concept at boundary 1-2.
• The SPD surge protector can provide protection for three-phase power system from lightning strikes and voltage surge
