The control stations with exterior PVC coating and interior yellow urethane are used for manual starting of AC or DC motors, status indicators presented by the motors through pilot lights and selection of starting mode of field engines.
80-84 (Shore A Durometer).
400 Volts/Mil at 60 cycles.
1000 hours (Atlas wet UV chamber).
200% min.
Polyvinyl chloride has a crystallization temperature of 5° F (-15° C).
PVC coating will burn if exposed to continuous flame or heat above 400°F (204°C).
Prolonged exposure to temperatures greater than 200°F (93°C) or fire may cause the PVC coating to release emissions potentially hazardous to the health of those exposed to them.
EFD/EFDB Control station with exterior PVC coating and interior with yellow urethane.
