Littelfuse/Commercial Vehicle Products

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 .

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 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 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 HB34 Series of transient surge suppressors are industrial high-energy Metal-Oxide Varistors (MOVs). They are designed to proide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. HB34 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 HB34 Series provides rigid terminals for through-hole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting.
