Surge Protective Devices

ASCO provides a range of surge protective devices that mount alongside panel boards and electrical equipment.

Protect traffic control equipment from transient overvoltages with ASCO's surge protective devices for power, data, video, and loop applications.

Monitor power fluctuations to reduce the resulting effects of voltage surges.

ASCO Surge Protective Devices mitigate power events that can damage components in critical equipment.

ASCO control panel-mounted surge devices will prevent missed or false zero crossover readings that require PLC reboot.

Built for the specific demands of medium voltage, UPS, rackmount, water treatment, lighting and rackmount applications.

Repetitive life-cycle capability, high-energy capacity, and years of proven service make the Model 560 a leading choice for high-risk locations and critical process equipment.

The Model 440 is non-modular and high-energy capable. It offers thermally protected, large block MOVs.

The Model 420 uses thermally protected MOVs, is tested as a UL 1449 Type 1 device and is in a NEMA 4X enclosure, making this an ideal choice for both panel and equipment locations.

The Model 277 is a series-connected , DIN or flange mountable, high frequency noise filter and surge suppressor. Its ideal applications include critical industrial loads drawing up to 20 Amps of continuous current.

Surge protective devices feature a wide range of indicators that identify operating status. This paper describes indicator options.

After lightning damaged costly groundwater pumping equipment, a museum turned to ASCO to develop a down-well surge protection solution.

500 SERIES Surge Protective Devices are designed with strict industry requirements in mind. This diverse family of products uses patented surge technology to provide survivability and exceptional performance.
