IEC 61643-11, EN 61643-11 and UL1449 ed.4 compliance

The DS250E is an extreme duty Type 1+2 designed to protect the entrance of the electrical installation. They are used to protect biphase, 3-phase or 3-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 DS250E is mounted on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.

INSTALLATION

DS250E-400 Type 1+2 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.

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