Claims

[Scope of utility model registration request]

A coil frame of a dart pot type electromagnet is disposed on the lower side of the frame that pivotally supports the handle, the latch plate, and the armature, and one end of the trip plate linked to the lower part of the handle is latched to the latch plate.
A tension spring is interposed between the other end of the movable contact whose center part is pivoted to the other end of the trip plate and whose one end faces the fixed contact plate and the upper end of the frame, and one end is attached to the terminal plate. The other end of the connected electromagnetic coil is connected to a movable contact via a braided conductor, and the armature unlatches the latch plate and trips the trip plate due to electromagnetic operation, causing the contacts to open. In a current circuit breaker, an electromagnetic coil is connected to the lower end of a substantially L-shaped conductor plate fixed along the end and upper surfaces of the coil frame, and the lower end of the braided conductor is connected to the upper end of the conductor plate. An overcurrent breaker that is connected to a conductor.
