Surge protection

SPHT12 products are DIN rail-mounted products designed in a compact pluggable housing for use as a Class I+II/Type 1+2 Surge Protective Device (SPD). SPHT12 uses a multi-cell, encapsulated GDT technology, to achieve a residual voltage like that of a MOV-based SPD, but in a footprint half the size of the market competition and without restrictions governing where on a network it may be installed.

Core Features

Compact and Pluggable Housing

The compact design allows for efficient use of space, and the pluggable housing makes maintenance straightforward.

Class I+II/Type 1+2 Protection

They provide robust protection against both direct lightning strikes (Class I) and switching surges (Class II).

High Dissipation Capacity

Capable of handling surges up to 100 kA (10/350 μs).

Leakage Current Free Topology

Ensures no leakage current, which is crucial for sensitive electronic equipment.

Low Residual Voltage

The devices have a low residual voltage of 1.5 kV, minimizing the risk of damage to connected equipment.

VDE Certified

They meet the stringent requirements of the IEC 61643-11 standard and are VDE certified.

Available types for SPHT12

SPH „AX“

Base, insert and auxiliary contact in one device
Iimp of 25 kA per phase
Suitable for applications with external lightning protection system (LPS I/II/III/IV)

SPH „NPE“

Suitable for TT and TN-S systems due to the 3+1 connection
Galvanic separated SPD path between neutral and protective earth

SPHT12 with the New Phase- GDT (PGDT) Technology

New Phase-GDT (PGDT) technology has been developed to optimize both voltage switching and voltage limiting SPD technologies to create an ideal Class I SPD in a DIN Rail design – where a compact package is possible using voltage switching technology but without the drawbacks of a high residual voltage or poor follow current rating.

Designed for higher requirements

Eaton‘s comprehensive range of surge protection devices offer just for the fraction of the cost of your valuable equipment, the peace of mind that your household is protected against the destructive power of surges.

This overvoltage protection was designed for buildings, which have to meet higher requirements from the risk assessment.

Reduces effect of overvoltages

The installation of surge protection devices is intended to ensure voltage limitation in accordance with the insulation coordination. This avoids dangerous sparking and the resulting fires.

Overvoltage protection devices must be installed to reduce the effects of overvoltages. This applies to the electrical systems of all buildings from residential homes up to public and telecommunications facilities.

A revolutionary way to secure your PV investment

The SPPVR surge protection device family ensures secure and durable photovoltaic installations by providing robust defense against overvoltage on the DC side, thus preserving equipment longevity and securing PV system durability in residential and commercial structures.
