Type 1+2+3 unipolar surge protector
25 kA on 10/350µs impulse
Low voltage Up
Internal disconnection, status indicator and remote signaling
Optimized to TOV
IEC 61643-11 and UL1449 ed.5 compliance

The products of the range DS250VG is an extreme duty Type 1+2+3 AC surge protector device designed to protect at the entrance of the electrical installation. This SPD is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (eg: buildings equipped with lightning rods). The `Spark gap + Varistor` technology allows a very low level of protection and an absence of following current. The DS250VG is mounted on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.

INSTALLATION

DS250VG-300 Type 1+2+3 AC surge protector - 1 pole is connected in parallel on the AC network and must be equipped with external fuses for short-circuit current protection

The total length of parallel connection wires to AC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
Wiring is made by screw connections. On some models, a distribution bus can be used.
The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
The cross sectional wire must be 6 mm² minimum for Type 2 SPD and 16 mm² for Type 1.
Local earthing resistance must be in compliance with the electrical rules.
