摘要： An interlock assembly for a circuit breaker prevents inadvertent installation or removal of the circuit breaker from a circuit breaker panel while current is flowing. The interlock assembly cooperates with the circuit breaker panel to physically prevent the circuit breaker from being inserted into the circuit breaker panel until the circuit breaker is put into a tripped state. Likewise, the interlock assembly cooperates with the circuit breaker panel to physically prevent the circuit breaker from being taken out of the circuit breaker panel until the circuit breaker is put into a tripped state. This ensures that the circuit breaker will not be inadvertently installed or removed from the circuit breaker panel while current can immediately flow or is flowing through the circuit breaker.

摘要： The circuit breaker is intended for installation in a low-voltage distribution board having a socket and having at least two busbars which are guided parallel, are held on the socket and are each associated with one pole conductor of a multiphase power supply system. This circuit breaker has an enclosure as well as a plug contact for making contact with one of the busbars. The plug contact can be positioned as a function of the position of the busbar with which contact is to be made, and is held on a contact mount, which can be moved transversely with respect to the busbars and can be locked to the circuit breaker enclosure. In a circuit breaker such as this, a pole conductor change from one busbar to another busbar can be carried out quickly and without the use of any tools.

摘要： A switch, having a mechanical user interface including a lever handle and an electrical socket interface including a set of contacts separable upon application of tension. The switch includes a handle guard and an extraction tool, adapted to apply sufficient tension to the switch to separate the contacts from the electrical socket, wherein the extraction tool has a first position and a second position, said extraction tool being adapted, upon application of tension when in said first position, to move the lever handle of the switch from an active to an inactive position before assuming said second position, and upon application of tension when in said second position to separate the set of contacts from the electrical socket.

摘要： A combined handle-guard and grip protects the actuator-handle of a circuit breaker from being inadvertently displaced during normal circuit breaker operation while also positioning a user's fingers to automatically trip the circuit breaker into a non-conducting state whenever the user grasps the grip surfaces of the handle-guard to remove or install the circuit breaker. In a preferred embodiment, the shield surfaces form a slot dimensioned to permit the unrestricted movement of the circuit breaker handle. A first grip surface is disposed at one of the slot. A second grip surface is disposed at the other end of the slot. A passageway in the second grip surface is shaped and positioned so that a distal portion of the circuit breaker actuator-handle extends through the passageway when the circuit breaker is in an on-position. When the user grasps the second grip surface, pressure is applied to the actuator-handle, tripping the circuit breaker into a non-conducting state whenever the circuit breaker is inserted or removed.

摘要： A circuit breaker mounting arrangement for use in a device such as a transfer switch includes a mounting member adapted for securement to the transfer switch. The circuit breaker includes a head portion having a reset member, and a rearwardly extending body portion which terminates in a rear end wall from which a pair of contact prongs extend. A mounting member is provided for each circuit breaker, and includes an internal recess or cavity adapted to receive the circuit breaker body portion. The mounting member further includes an end wall which in part defines the recess, and a pair of engagement members are mounted to the end wall. The engagement members are configured to receive the circuit breaker prongs when the circuit breaker is inserted into the passage of the mounting member, for establishing an electrical connection between the circuit breaker prongs and the engagement members. Each engagement member includes an external connection area adapted to be wired into the circuitry of the transfer switch, and the circuit breakers can be removed from the mounting members and selectively replaced as required without the need to disassemble the transfer switch to remove the circuit breaker from the electrical circuitry.

摘要： A safety arrangement for the protection of life and matter against damage from electrical current applied to nonstationary electrical appliances connected to grounded supply networks. A core-balance protective switch with a nominal tripping current below 50 milliamperes precedes the appliances. The protective conductor of the safety arrangement leads, over at least one switch contact of the protective switch, to one or several primary windings of the balance transformer of the core-balance protective switch. The total number of turns of one of the primary windings for the connection of one of the phase conductors or of the neutral conductor of the supply network. In the core-balance protective switch a voltage dependent resistor arrangement is connected in series to the protective conductor with such characteristic that its resistivity is high at low voltages but very small at higher voltages. This voltage dependent resistor arrangement consists of two identical single voltage dependent resistors with oppositely directed characteristics, connected in series to each other and to a limiting resistor.
