The HFA relays are electric - reset,
relays that are suitable for application where the operating characteristics and
ratings as described in this book are required.
The TYPE HFA relays are available with coil ratings for standard voltages up to
575 volts at 25, 50 or 60 cycles, and up to 250 volts DC.
The operating coil is continuously rated but the reset coil has a five ( 5 )
second intermittent rating.
The current-closing rating of each contact is 30 amperes.
rating is 12 amperes continuous or 30 amperes for one minute.
