Type 1 + 2 protectors against transient overvoltages should be tested with 10/350 µs lightning impulse wave and 8/20 µs wave, combining the capacity to absorb lightning current with low residual voltage.

Surge protective devices prevent excessive quantities of energy from entering the system. A lightning strike or utility power surge can cause equipment failure, resulting in hundreds of thousands of volts. However, external voltage anomalies generated by lightning or utility power only account for 20% of transient surges. These surges occur frequently and last longer, and they can damage sensitive equipment inside the facility, even if they are less powerful. A tight protection scheme is suggested in the Spanish Low Voltage Regulations (REBT ITC23).

Type 1 + 2 protectors against transient overvoltages should be tested with 10/350 µs lightning impulse wave and 8/20 µs wave, combining the capacity to absorb lightning current with low residual voltage.
Type 2 protectors against transient overvoltages should be tested with 8/20 µs current impulse wave, simulating lightning secondary effects.
This SPD is plugged directly in the same socket as the load to be protected. It contains effective protection against transient overvoltages for single-phase power supply lines. Tight protection according to the cascade protection recommended in the Spanish Low Voltage Regulations (REBT ITC23).
This protector is designed for its connection inside the cable channels that feed the sockets. Especially designed for outdoor and street lighting. It contains effective protection against transient overvoltages for single-phase power supply lines. Tight protection according to the cascade protection recommended in the Spanish Low Voltage Regulations (REBT ITC23).
