Abstract

A low-voltage circuit breaker has a fixed contact and a movable contact which is attached to a pivoted contact carrier. Between the contact carrier and the movable contact, a contact pressure spring is arranged, which is designed as a coil compression spring. The contact carrier has an arm which extends to the vicinity of the contact-making end of the movable contact. The arm carries a setscrew which is positioned to act centrally with respect to a contact overlay of the movable contact. The setscrew limits the lifting of the movable contact or the contact overlay to the desired small extent, when a large current flows through the circuit breaker and exerts electrodynamic force on the movable contact.
