Footnotes:
1.
Circuit breaker is in closed position.
2.
User must supply external time delay (typically using setting in reclosing relay) to assure the minimum reclose time interval of 0.3 s in accordance with ANSI/IEEE.
3.
For ac tripping supply, capacitor trip is used. If ac trip is used, the ac supply must be from a highly reliable power source (for example, from an uninterruptible power
supply).
4.
Consult factory for -50 °C.
