It takes about 15 minutes to install or replace the assembly.

General Description

For the retrofill, the following information is for either installing or replacing the mechanism for the position switch (not the position switch itself) on the retrofill circuit breaker; the position switch assembly is already mounted in the compartment; if not, it can be ordered as an option. The mechanical subassembly is a simple ancillary lever-and-tension device that pushes against the position switch arm when the retrofill breaker is racked in completely. This device, mounted on the cassette using simple hardware, is called the actuator or actuator bracket. Its purpose is to make a strong contact with the position switch when the racked-in breaker provides mechanical pressure against the arm. The mechanical force on the lever and tension mechanism then activates the position switch. The position switch, when activated, determines that the racked-in circuit breaker is connected.

Figure 1 is an example of an installed position switch. It is activated mechanically when the breaker is racked in.
