Abstract
This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is accomplished by operation of a ratchet and pawl assembly. A reset system interfaces with the charging system to reset the charging system after the operating springs have been discharged.
Claims19
An industrial-rated circuit breaker for high level overcurrent protection comprising:
- an insulative base;
- an insulative cover above said base, said cover enclosing a closing shaft and a handle drive gear arranged for charging a circuit breaker closing spring;
- a handle connecting with said closing shaft said handle drive gear and a locking pawl allowing an operator to provide closing forces for charging said closing spring;
- an intermediate latch arrangement operatively connecting said locking pawl with said drive gear when said closing spring is receiving said forces and releasing said locking pawl from said handle drive gear when said closing spring becomes fully charged;
- a reset assembly within said cover interacting between said handle drive gear and said locking pawl to operatively connect said locking pawl with said handle drive gear when applying said closing forces and disconnect said locking pawl from said handle drive gear when said closing spring is fully charged;
- and
- a closing cradle interacting with said intermediate latch and said reset assembly for initiating charging of said closing spring.
