DACN10-20-275

DACN10 AC surge protector is used for the 'secondary' protection of the single-phase networks against the surge voltages creating by lightning. DACN10 is equipped with an internal thermal safety which will disconnect the unit from the AC network in case of end of life. This disconnection is signaled by the extinction of the green LED on the front panel. Very compact, the DACN10 surge protector must be installed close by the equipment to protect, downstream a 'primary' surge protector. DACN10 provides both a common and differential mode protection.

INSTALLATION

DACN10-20-275 Type 2/3 AC surge protector - single-phase are connected in serial or parallel on the AC network and must be equipped with external fuses for short-circuit current protection

The total length of 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).
