STATIONARY CONTACT ASSEMBLY INCLUDING FIRST AND SECOND STATIONARY CONTACTS, AND CIRCUIT INTERRUPTER AND TRANSFER SWITCH EMPLOYING THE SAME
First Claim
1. A stationary contact assembly comprising:
- a conductor;
a first stationary contact disposed on said conductor; and
a second stationary contact disposed on the same said conductor proximate said first stationary contact,wherein said first stationary contact has a first contact surface disposed a first distance from said conductor,wherein said second stationary contact has a second contact surface disposed a second distance from said conductor, andwherein said second distance is smaller than said first distance.

Abstract
A circuit interrupter includes a movable contact assembly having a movable contact, a stationary contact assembly, and an operating mechanism. The stationary contact assembly includes a conductor, a first stationary contact disposed on the conductor, and a second stationary contact disposed on the same such conductor proximate the first stationary contact. The first stationary contact has a first contact surface disposed a first distance from the conductor. The second stationary contact has a second contact surface disposed a second distance from the conductor. The second distance is smaller than the first distance. The operating mechanism is structured to move the movable contact assembly and cause the movable contact to engage or disengage from at least the first contact surface of the first stationary contact.
