General Information

Figure 16.3: Class 8502 Type VF

The Class 8502 Type V vacuum contactor is a 3-pole device rated 1500 V that meets UL508 (1.5 kV) and CSA standards. Vacuum technology offers long life and low maintenance in a compact, lightweight design. The contactor is suitable for contaminated atmospheres because the main contacts are sealed in vacuum bottles. In addition, since gravity is not used to assist contactor operation, the Class 8502 contactor can be mounted in any plane without special modifications. Type V vacuum contactors are designed for the control of inductive or non-inductive loads at voltages from 200–1500 Vac. For How to Order Information, see page 16-28. NOTE: In Table 16.113, replace the three bullets (●●●) in the catalog number with the coil voltage code. Refer to the standard coil voltage codes listed in Table 16.78 Coil Voltage Codes, page 16-28.
