GENERAL
SMC Metal Oxide Surge Arrestors provide surge protection for DC distribution systems in transit, industrial and mining applications. The arrestors are designed to be mounted with the metal cap pointed up on rectifiers, substations, DC feeders, catenary poles, at the power rail, or on a vehicle. The unit should be mounted as close as possible to the device it is protecting. The arrestor should be connected to an appropriate-sized conductor for anticipated surges. Arrestor selection is based on maximum continuous operating voltage (MCOV). When grounded, the connection should be less than 5 Ohms.

DESCRIPTION
The Surge Arrestors utilize metal oxide technology, which has been proven in the station and intermediate class arrestors. They are designed to operate in temperatures not exceeding 60∞C. The arrestor housing is manufactured of impact-resistant UV stabilized polyester glass compounds with the element encapsulated. The element’s encapsulated area also has a high dielectric sleeve for added protection. The unit is sealed with a stainless steel cap. The connecting studs and mounting hardware are manufactured from corrosion-resistant stainless steel. Energy discharge capacity is 2.6 kJ/kV for current < 500 A.

DC Surge Arrester

The Swartz Engineering DC surge arrester is a device that protects electrical equipment from damage caused by overvoltages. Overvoltages can be caused by lightning strikes, switching surges, or other transient events. The Swartz Engineering DC surge arrester uses a metal oxide varistor (MOV) to absorb the overvoltage and protect the equipment.

The Swartz Engineering DC surge arrester is available in a variety of voltage ratings and configurations. The voltage rating is the maximum voltage that the arrester can withstand without damage. The configuration refers to the number of arresters that are connected in parallel. The Swartz Engineering DC surge arrester can be connected in parallel to increase the surge protection capacity.

The Swartz Engineering DC surge arrester is a reliable and cost-effective way to protect electrical equipment from damage caused by overvoltages. The arrester is easy to install and maintain, and it is available in a variety of voltage ratings and configurations to meet the needs of a variety of applications.

Here are some of the features of the Swartz Engineering DC surge arrester:

  • Metal oxide varistor (MOV) technology
  • Wide range of voltage ratings
  • Variety of configurations
  • Easy to install and maintain
  • Cost-effective
