Abstract
An arc fault circuit breaker comprising an electronics portion that is interconnected with a mechanical portion is presented. A plunger arm affixed to the end of a plunger shaft of a solenoid connects the electronics portion with the mechanical portion. A protrusion is provided to assist in assembly of the circuit breaker. The protrusion depends from the plunger arm. An assembler applies a light downward force with one finger on the protrusion and the plunger arm tends to assume a position at right angles to the surface of the printed circuit board. When the electronics portion is connected with the mechanical portion, the plunger arm is properly aligned and it enters into the slot. If the electronics portion is slightly offset, the assembler's finger on the protrusion can move the plunger arm slightly to align the plunger arm. Thus, the invention enables an assembler to hold and guide the plunger arm into the correct position with one hand while assembling the circuit breaker.
