Type 1 + 2 multipolar AC surge protector
Iimp total : 100 kA (10/350µs impulse)
Imax : 140 kA (8/20µs impulse)
Internal disconnections, status indicator and remote signaling
Conforme NF EN 61643-11, IEC 61643-11, UL1449 ed.5

The DS500E range of surge protectors are Type 1 + 2, very high power, they are intended to be installed at the entry of the Low Voltage installation. They are used to protect single-phase, three-phase or three-phase + Neutral networks in common mode or in common and differential mode. The 'Multi-Varistor' technology used allows the best possible behavior for the LV network (no follow-on current). The DS500E range is installed on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.

INSTALLATION

DS504E-320/G Type 1+2 AC surge protector - 3-phase+N are 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.

Further information can be found in IEC 61643-12 standard (selection and application principles for low voltage SPD).
