摘要： A low voltage circuit breaker having a housing of insulating material separated into an upper part and a lower part. A slot is provided one side wall of the lower part beginning at the parting line and extending to the lower edge of the lower part in which wires leading to an auxiliary device can be installed. An outlet is provided at the separation for these wires. The slot makes it possible to arrange several identical low voltage circuit breakers with connected auxiliary wires directly next to each other.

摘要： A multi-pole vacuum switch has an insulation assembly for each pole, which is composed of shell-like insulating elements. In addition to a space provided for receiving the vacuum interrupter, chambers are formed by wall sections, which are provided for receiving mechanical and electrical components of a pole unit. In particular, these electrical components are a loop-shaped, flexible strip conductor, a lever arrangement, contact springs and current transformers. Tensioning bolts which penetrate all the pole units connect the pole units to a pole block. The invention is suitable for use in vacuum power switches, in particular for low operating voltages.

摘要： A low-voltage circuit breaker of compact design has a housing of insulating material with several parallel disposed chambers. A switching mechanism designed as a structural unit is provided in one of the chambers. The other chambers comprise compartments for switching path contacts. The switching mechanism comprises a U-shaped carrier for all moving parts. In particular, a drive shaft with a coupling part, such as a key, as well as a tripping shaft, likewise having a coupling part such as a slot, are provided. A pole control shaft is provided for actuating the switch contacts and is provided at its end with a coupling part such as a slot which comes into engagement with the coupling part of the drive shaft of the switching mechanism if the latter is built into the switch gear.

摘要： 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.
