AC Surge Protection Device SPD T2+T3 SLP20 series


Transient and power frequency overvoltage protection

Surge protection devices (SPD) Electrical power supply networks to IEC/EN (DIN rail)

Type 2+Type 3 / Class C+Class D / Class II+Class III for use in AC power supply systems

Surge protection portfolio includes solutions for protecting systems up to 1,000 V a.c. against surges caused by atmospheric discharge and switching operations.

The AC Surge Protection Device SPD T2+T3 SLP20 line is a group of Class III Surge Protective Devices. They are intended as fine protection against transient overvoltage, installed downstream to Class II SPDs. The application field of SLP20 is the protection of sensitive electronics used in or close to distribution board, typically home automation, IT systems etc. The Y connection of functional elements provides balanced protection of L and N conductor towards PE thanks to identical MOVs for both working conductors and full isolation due to connection to PE via Spark Gap.

Class III SPDs should be installed maximum 5 meters from the protected device. Coordination with Class II SPDs SLP20 is defined also for near installation. To reach best parameters, it is recommended to install both classes with a mutual distance of 5 meters of connecting cables.

The design of AC Surge Protection Device SPD T2+T3 SLP20 is based on Metal Oxide Varistors. Such a design provides a very low response time. The modular design with plug-in inserts allows simple and quick replacement of function modules in case of MOV is beyond if its lifespan due to often occurrence of overvoltage peaks.

FAQ

Q1: Selection of surge protector

Al: The grading of the surge protector (commonly known as lightning protection) Is assessed according to the IEC61024 subdivision lightning protection theory, which is installed at the junction of the partition. Technical requirements and functions differ. The first-stage lightning protection device is installed between the 0-1 zone, high for the flow requirement, the minimum requirement of EN 61643-11 / IEC 61643-11 is 12.5 ka (10/350), and the second and third levels are installed between the 1-2 and 2-3 zones, mainly to suppress the overvoltage.
