Varistor Products High Energy Industrial HA Varistor Series HA Series transient surge suppressors are industrial high energy metal-oxide varistors (MOVs). They are designed to provide secondary surge protection in the outdoor and service 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”. See Ratings and Specifications table for part number and brand information. ® ® Features • Wide Operating Voltage Range VM(AC)RMS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .110V to 750V • Two Disc Sizes Available . . . . . . . . . . . . . . . . . . . . . 32mm and 40mm • High Energy Absorption Capability. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .WTM = 170J to 1050J • High Peak Pulse Current Capability,. . . . . . . . . . . . . . . . . . . . . . . . . . .ITM = 25,000A to 40,000A • Rigid Terminals for Secure Mounting • Available in Trimmed Version for Through Hole Board Mounting Designation “HC” • No Derating Up to 85oC Ambient AGENCY APPROVALS: Recognized under the components program of Underwriters Laboratories.

The power so developed must be within the specifications shown on the Device Ratings and Specifications table for the specific device. Furthermore, the operating values need to be derated at high temperatures as shown in Figure 1. Because varistors can only dissipate a relatively small amount of average power they are, therefore, not suitable for repetitive applications that involve substantial amounts for average power dissipation. 100 90 80 70 60 50 2 Varistor Products High Energy Industrial HA Varistor Series Pulse Rating Curves 50,000 20,000 10,000 SURGE CURRENT (A) 1 2 DISC SIZE 32mm V111HA32 - V751HA32 50,000 1 20,000 10,000 SURGE CURRENT (A) 5,000 2,000 1,000 500 200 100 50 INDEFINITE 20 100 1,000 IMPULSE DURA TION ( µs) 10,000 20 10 20 INDEFINITE 100 1,000 IMPULSE DURA TION ( µs) 10,000 102 10 3 10 4 105 10 6 2 10 DISC SIZE 40mm V111HA40 - V751HA40 5,000 10 2 2,000 10 1,000 103 500 104 5 200 10 100 50 20 10 106 FIGURE 5.
