AC Surge Protective Device T2 SLP40 series


Transient and power frequency overvoltage protection

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

Type 2 / Class C / Class II 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.

Type 2 / Class II
Ability to discharge induced voltage surges (8/20 μs). Suitable for the second level of protection in supply distribution panels in which Type 1 protectors are installed, or for the first level of protection for applications not exposed to direct strikes and with no external lightning protection system. EN 61643-11 / IEC 61643-11.

LSP is the line of AC power surge protectors is designed to cover all possible configurations in low voltage installations. They are available in many versions, which differ in:
  • – Type 2
  • – AC network configuration (Single/3-Phase)
  • – Discharge currents (Iimp, Imax, In)
  • – Protection technology (varistors, GDT)
  • – Features (plug-in, remote signaling, compact)

The AC Surge Protective Devices T2 SLP40 line is a group of Class II Surge Protective Devices. They are intended as a protection against transient overvoltage caused by fast switching operations or indirect hits of lightning strokes (residuum effects).

It is recommended to install Class II SPDs every 10 – 20 meters of cable length repetitively, typically to main and sub-distribution boards. The SLP40-440 are designed for direct coordination with Class I SPDs of line FLP25. In case of SLP40-275, the coordination with the line FLP25 is done by means of 10 m cable length.

The design of SLP40 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.
