The ZA Series of transient voltage surge suppressors are radial-lead varistors (MOVs) designed for use in the protection of low and medium-voltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity. These devices are available in five model sizes: 5, 7, 10, 14, and 20mm, and feature a wide V DC voltage range of 5.5V to 615V. See ZA Series Device Ratings and Specifications table for part number and brand information.

The LA Series of transient voltage surge suppressors are radial-lead varistors (MOVs) that are designed to be operated continuously across AC power lines. These UL recognized varistors require very little mounting space, and are offered in various standard lead form options. The LA Series varistors are available in four model sizes: 7mm, 10mm, 14mm, and 20mm; and have a V M(AC)RMS voltage range from 130V to 1000V, and an energy absorption capability up to 360J. Some LA series model numbers are available with clamping voltage selection, designated by a model number suffix of either A or B. The "A" selection is the standard model; the "B" selection provides a lower clamping voltage. See LA Series Device Ratings and Specifications table for part number and brand information.

The C-III Series of metal oxide varistors are specifically designed for high surge energy absorption ratings. This is achieved through a special dielectric material formulation which also results in higher repetitive surge ratings than other MOV types. The C-III series is primarily intended for use in AC line Transient Voltage Surge Suppressor (TVSS) product environment and other similar applications requiring high transient energy and peak current capability in a relatively small package size. The C-III series is supplied in 14 and 20mm disc versions with various lead options. These types are shipped in bulk or Tape and Reel packaging. Part number and brand information is provided in the Ratings Table.

The PA Series of transient surge suppressors are metal-oxide varistors (MOVs) featuring a rigid base mount package construction, and are useful in applications which are subject to vibration. The UL and CSA recognized varistors are available in a wide range of operating voltages, from 130V to 660 V V M(AC)RMS . The base-mount package has a quick-connect tab terminal that provides a fast, secure lead attach. The mounting base forms the second electrical connection, usually chassis ground. Meeting rigid NEMA standards, PA series varistors have a creep and strike distance capability that minimizes breakdown along the package surface.

The CA Series of transient surge suppressors are industrial high-energy disc varistors (MOVs) intended for special applications requiring unique electrical contact or packaging methods provided by the customer. The electrode finish of these devices is solderable and can also be used with pressure contacts. Discs of the same diameter may be stacked. This series of industrial disc varistors are available in three diameter sizes of 32, 40, and 60mm, with disc thicknesses ranging from 1.8mm minimum to 32mm maximum. They offer a wide voltage range of from 130 to 2800 V M(AC)RMS .
