Lighting protection is essential in any environment where electrical equipment and machinery are present. For high voltage applications, SPD-277S-20KA-EILR is an enclosed protection device specifically designed to protect electrical equipment from lighting.

The SPD-277S-20KA-EILR is essentially a complete lightning protection system in one box. It is built with a self-contained device containing a resistor, a spark gap, an impedance transformer, and an arc guard, all designed to suppress voltage spikes due to lighting strikes. In addition, it is fitted with metal oxide varistors (MOVs) for additional protection from induced surges. The SPD-277S-20KA-EILR has a power handling capacity of up to 277S and 20KA, offering reliable protection for electrical equipment and installations.

The working principle of the SPD-277S-20KA-EILR is straightforward and effective. When a lighting strike hits the electrical system, it induces a large electrical current. This current is diverted to the SPD-277S-20KA-EILR where it is spread over multiple protective components such as impedance transformer and MOVs. This reduces the peak current induced by the lighting strike. At the same time, the spark gap and arc guard of the SPD-277S-20KA-EILR work together to stop an arc from forming. As a result, the voltage level of the incoming strike is significantly reduced at the source.

The SPD-277S-20KA-EILR is suitable for a wide range of applications, from industrial and manufacturing facilities to residential homes. It is also ideal for outdoor applications since it is housed in a weatherproof case. The SPD-277S-20KA-EILR can also be combined with other surge protection devices, such as surge suppressors and line fault indicators, to provide additional protection from damaging surges and other electrical problems.

In summary, SPD-277S-20KA-EILR is an enclosed protection device specifically designed for high voltage applications. It is built with a self-contained device containing a resistor, spark gap, impedance transformer, and arc guard, all designed to suppress voltage spikes due to lighting strikes. The SPD-277S-20KA-EILR is suitable for a wide range of applications and can be combined with other surge protection equipment for added protection. This makes it an ideal choice for protecting electrical equipment from damaging electrical surges.
