Features:
20kA Class C for 3 Phase Supply.
It is compact devices designed to protect 3-phase+neutral networks at the main switchboard.
The product is complying with the standards: EN 61643-11, CEI 61643-11, UL1449 ed. 4 compliance.
The protection circuitry is based on high energy varistor with thermal disconnection devices.
Easy to operate.
There is an indicator on the cartridges to signal failure mode.
Long service life.
The BR-20 is DIN rail mounted and features replaceable modules for the safest and easiest installation and maintenance.
Excellent functionality
Consistent plug ability(even for N/PE spark gap)
BR-20 series are designed to protect against lighting surge voltages. These units must be installed in parallel on the AC networks to be protected and provide common and differential modes protection.
Thermal disconnect device for each individual connector
Surge Protection Device / Arrester are for protection against switching surges.
With or without floating remote indication contact
Time of response<25ns.
The color of the visible window shows operating status, green means normal, red means abnormal.
