#This invention relates to circuit breakers and, more particularly, to a novel and highly effective circuit breaker that is considerably less expensive than conventional circuit breakers of the same class.

#A better understanding of the objects, features and advantages of the invention can be gained from a consideration of the following detailed description of the preferred embodiments thereof, wherein:

#FIG. 1 is an exploded perspective view of a circuit breaker constructed in accordance with the invention;

#FIG. 2 is a top plan view of a portion of the structure of FIG. 1;

#Fig. 1 shows a circuit breaker 10 constructed in accordance with the invention. A solenoid 12 is mounted in position on a centerline 14 between two breaker poles 16, 18. It is held in position by walls 20, 22 projecting from a wall 24 of a housing 26. Leads 28, 30 of the solenoid 12 are aligned with terminals 32, 34, respectively on a circuit board 36.

#The solenoid plunger 38 extends through a hole 40 in the circuit board 36.

#Thermal calibration screws 42, 44 are employed for calibration before the circuit board 36 is installed.
