All INDELEC Surge Protection Devices have been successfully tested in Blitzcshutz & EMV Technologiezentrum (BET) laboratory inMenden, Germany. Test Reports are available on request.

Tests are carried out with standardized wave forms defined inIEC 61643-1 standard which aim to represent transient overvoltage effects on the surge protection devices.

Surge Protection Cabinets InstallationSurge Protection Cabinets InstallationInstallation of Type 1 (Class B) Surge Cabinet at the Main Switchboard, directly on the busbars

Type 1 Surge Protection Cabinet

Main/Primary Switch of the network

Common mode protection (C1): the SPD are wired between Phases and Earth in addition to Neutral and Earth.

In order to gain maximum protection efficiency, it may be necessary to create a "coordination diagram" requiring a primary SPD level at the main switchboard with C-DGV400 or C-DGM400, and a secondary SPD level close to the sensitive equipment with C-DGT400or C-DGX400.

Plug & Play SolutionsINDELEC Surge Protection Cabinets provide a suitable, efficient and reliable protection for any low voltage network & equipment. Their installation is very easy and requires a minimum time!

State-Of-The-Art Pre-Wiring & AssemblyWiring and assembly of Surge Protection Devices (SPDs) is very important. One of the major rule to follow is called the "50cm rule".As per this rule, detailed in the IEC 61643-12 standard, the total length of cable between 1 phase and the earth, through the SPD, should not be more than 50cm in order to keep the Up (residual voltage) value as low as possible. if its not respected, equipments may get damaged. INDELEC Surge Protection Cabinets are wired and assembled by professional as per IEC61643-12 standards and strictly follow all rules given.

Easy Control & MaintenanceINDELEC Surge Protection cabinets include Miniature Circuit Breakers (MCBs), thermal disconnectionmechanisms with corresponding indicators, as well as remote contact signalizations. It enables users to ascertain the operating conditions at all time and eventually replace SPD modules easily maintaining the continuity of service. Control and maintenance activities are therefore highly simplified.

Limit Induction effectsIf SPDs are directly installed in electrical panels, an occurring surge can generate instabilities in the network and damage equipments. This is due to the induction effect created by the surge in the other lines located in the panels. Hence, it is HIGHLY recommended to install SPDs in a separate cabinet. INDELEC Surge Protection Cabinets offer this additional protection since they isolate surges and prevent from induction effects.

Prevent from Short CircuitsINDELEC Surge Protection include MCBs as back-up protection preventing the network from any short circuit.

Coordination by inductor unit

Coordination by wiringSecondary SPDPrimary SPD

Coordination is required in both of following cases:1) Highly sensitive equipment to be protected 2) Extended distance greater than 30m of wire between primary and secondary SPD level

All Mode - Common + Differential protection (C2): each SPD is wired between Phase and Neutral and a special module is wired between Neutral and Earth. This type of wiring gives an enhanced protection.
