voltage release is operated. A “make”
contact closes and a “break” contact
opens when the alarm/lockout switch
operates. The switch automatically
resets when the circuit breaker is reset.

F-Frame circuit breakers are factory sealed. Underwriters Laboratories, requires that internal
accessories be installed at the factory. Internal accessories are UL listed for factory installation
under E7819. Where local codes and standards permit and UL listing is not required, internal
accessories can be field installed. Accessory installation should be done before the circuit
breaker is mounted and connected.
Includes 24-inch (609.6 mm) external pigtail leads,18 AWG (16-.010).
Suitable for mounting in right pole only of 2- or 3-pole breaker.
