Product catalog summary

Overview: The document outlines the technical specifications for the SLP20 series of AC Surge Protective Devices (SPDs), intended for use in sub-distribution boards. These devices comply with IEC 61643-11:2011 and EN 61643-11:2012 standards and are compatible with TN-S, TN-C, and TT network systems.

Specifications: The SPDs are available in various models with nominal AC voltages of 230 V and 400 V. They feature a maximum continuous operating voltage (Uc) between 320 V and 440 V, a nominal discharge current (In) of 10 kA, and a maximum discharge current (Imax) of 20 kA. The devices use high energy Metal Oxide Varistors (MOV) and have a pluggable housing design.

Protection and Compliance: The SPDs provide protection modes such as L-PE, N-PE, L-PEN, and L-N, with surge ratings classified as Class II+III / Type 2+3. They include thermal protection and offer operating state/fault indication through green (ok) and red (defect) signals. Optional remote contacts are available for enhanced monitoring.

Mechanical and Environmental: The devices operate within a temperature range of -40 ºC to +70 ºC and a humidity range of 5% to 95%. They are designed to withstand atmospheric pressures from 80 kPa to 106 kPa and altitudes from -500 m to 2000 m. The housing is made of thermoplastic with an extinguishing degree of UL 94V-0, and the degree of protection is IP 20.

Installation and Ordering: The SPDs are mounted on a 35 mm DIN Rail (EN 60715) and have a terminal screw torque of 39.9 Ibf·in [4.5 Nm]. They support a conductor cross-section of up to 2 AWG (solid, stranded) or 4 AWG (flexible). Detailed ordering codes are provided for different models and configurations, including options with remote contacts.

Electrical Characteristics: The response time is less than 25 ns for L-N and less than 100 ns for N-PE. The maximum back-up fuse is 63 A gL / gG, and the short-circuit current rating is 10 kA. There is no residual current, and voltage ratings vary with Uc ranging from 150 V to 440 V.

Features: The devices include thermal protection and provide operating state/fault indication with green for OK and red for defect. Optional remote contacts are available with specific switching capacities.

Order Information: Various ordering codes are available for different configurations and spare modules.

Installation and Configuration: Connection diagrams are provided for TN-S, TT (Three-phase, 3+1) systems, and the internal configuration includes pluggable single and multi-pole SPDs.

Packaging: The standard order quantity is 24 units for complete units and 120 units for spare plugs, with packaging dimensions of 260 × 220 × 330 mm.
