1-0 INTRODUCTION
General Information
The electrical operator (Figure 1-1) is a dual-solenoid
mechanism for local and remote circuit breaker ON and
OFF (reset) switching. The electrical operator is mount-
ed on the cover of the circuit breaker and provides high
speed switching with operating times of less than 5
cycles (80 ms), making it suitable for small generator
synchronizing operations. The electrical operator has a
terminal block for control connections. Catalog numbers
and electrical rating data are shown in Table 1.1. The
electrical operator is Underwriters Laboratories, Inc.
Iisted as a circuit breaker accessory suitable for field
installation under UL File E64983
➀
.
The electrical operator is suitable for application with 3
and 4-pole Series C circuit breaker types J
-Frame and
K
-Frame.
