Technical data MTL surge protection EPS 01-107 Rev V MTL ...

surge protection solution for process equipment, I/O systems and communications networks. The exceptionally high packing densities are the consequence of an ultra slim ‘footprint’ for individual modules which can thus ‘double-up’ as feedback terminals. Each module provides full hybrid surge protection for 2 and 3 wire loop protection.

Lightning and surge protection - basic principles

Surge protection devices should ideally operate instantaneously to divert a surge current to ground with no residual common-mode voltage presented at the equipment terminals. Once the surge current has subsided, the SPD should automatically restore normal operation and reset to a state ready to receive the next surge.

Guide to Surge Protection Devices - Hager

Surge protection needs to be selected such that their voltage protection level (Up) is lower than the impulse withstand capability of the equipment to be protected. 534.2.3.1.1 suggests that this value should be referred to category II of Table 44.3. This for a …

Transient Voltage Surge Suppressors

• Voltage protection level U p The voltage given by the surge protective device, while diverting the surge current to the ground U p, must not exceed the voltage withstand value of the equipment connected downstream. • Maximum operating voltage U c The value of voltage that the surge protective device can be permanently connected to has to ...

Surge protection devices - NHP

Surge Protection Devices (SPDs) are installed in parallel upstream from electrical equipment in a position such that, during any excessive voltage event, the SPD will act as a low-impedance path to earth. This channels the high volta-ge energy away from the downstream equipment before its
