Metal Oxide DC Surge Arrestor

Our Swartz Engineering metal Oxide Surge Arrestor provides a level of AC and DC protection systems for transit and high electrical systems. Arrestors are mounted and designed with the cap up feature to protect against electrical arcs. They can provide protection at maximum continuous operating voltage.

Swartz Engineering has been providing surge protection for years across the globe.  Swartz’s arrestor units are designed to protect personnel and equipment against voltage transients in transit applications, on rail cars or trucks, power stations, substations, and any location where electrical surges can occur.

The metal oxide arrestor unit consists of aluminum electrodes in a ceramic tube encapsulated by epoxy. These are not designed to be used as surge diverters, but rather to protect connected equipment against power surges. They should be installed so that the operating voltage is applied across the components either by direct or indirect connection usually through other protection. The device can offer protection in difficult environments and they are guaranteed to withstand extreme temperatures not exceeding 60∞C.

The capacity for energy discharge is astounding and Swartz has been fine-tuning these products to offer support in emergencies. The device is rated to a discharge capacity at 2.6 kJ/kV for current < 500 A.  Another important aspect is that they are made from environmentally-friendly materials and Swartz ensures that the components have been tested to ensure compliance with RoHS directive 2002/95/EC.

Components are created under strict manufacturing standards and with the utmost quality control in mind. The creators of the arrestor wanted a product that could offer easy mounting alongside proven protection.

The Swartz Engineering metal oxide surge arrestor provides protection for high voltage, transit and electrical systems across the globe. The unit can provide protection at the maximum continuous operating voltage and can be customized to the needs of each client.  If you would like to learn more about these products from Swartz, contact us today.
