The HB34, HF34, and HG34 Series of transient surge suppressors are industrial high-energy Metal-Oxide Varistors (MOVs). They are designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. Applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator

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 DHB34 Series of transient surge suppressors are industrial highenergy Metal Oxide Varistors (MOVs). They are designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. DHB34 applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications. The DHB34 Series provides rigid terminals for through-hole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting. See Ratings and Specifications table for part numbers.Note: Ratings are for each individual element in dual assembly. Average power dissipation of transients not to exceed 2.0W per varistor element (2 varistors per device).

HA Series transient surge suppressors are industrial hgh energy metal-oxide varistors (MOVs). They are designed to provide secondary surge protection in the outdoor and servie entrance environment (distribution panels) of buildings, and also in industrial applications for motor controls and power supplies used in the oil-drilling, mining, and transportation fields. The design of the HA Series of metal oxide varistors provide rigid terminals for screw mounting. Also available in a clipped lead version for through hole board placement or to accommodate soldered leads-designation "HC".

The BA and BB Series transient surge suppressors are heavy-duty industrial metal-oxide varistors (MOV) designed to provide surge protection for motor controls and power supplies used in oil-drilling, mining, transportation equipment and other heavy industrial AC line applications. These UL-recognized varistors have similar package construction but differ in size and ratings. The BA modelsa are rated from 130 to 880V M(AC) . Both the BA and BB Series feature improved creep and strike capability to minimize breakdown along the package surface. This package design provides both complete electrical isolation of the disk subassembly, and rigid terminals to insure secure wire contacts. Remove 'a package surface' second occurance. See BA/BB Series Device Ratings and Specifications table for part number and brand information.

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 .
