H02B 1/20

US Classification:

361652, 361 42, 361648, 361603, 361623, 361634

Abstract:

A current-sensing assembly comprising a housing and first and second current transformers contained in and fixed in position by the housing. The assembly includes at least one conducting pin corresponding to each of the first and second current transformers and inserted through the housing to expose a top end and a bottom end. The top end of the pin is electrically coupled to an end of the conducting wire of the corresponding current transformer through a window in the housing coinciding with the current transformer. The top end of a common pin is electrically coupled through the window to the opposite end of the coil conductor. The bottom end of each pin is configured to be coupled to a printed circuit board. The housing includes first and second elongated rings passing substantially through the centers of the current transformers and configured to accept first and second current lines.

International Classification:

H05K 7/00

US Classification:

361781

Abstract:

A circuit breaker includes a housing, a rigid circuit board, and a flexible circuit board. The rigid circuit board is enclosed within the housing and has a main surface for supporting an electronic component. The flexible circuit board has a first end that is directly attached to an edge of the rigid circuit board.

International Classification:

H01H 7312

US Classification:

200 17R

Abstract:

An accessory module monitoring and controlling the status of a circuit breaker. The accessory module attaches to the side of a circuit breaker and has a mechanism similar to the mechanism in a circuit breaker. The mechanism has multiple positions that correspond to the multiple states of a circuit breaker. Suitably shaped actuators transform the relatively large-scale motions of the mechanism into small-scale motions and transfers these to buttons on switches. Depressing these switches, depending on the position of the mechanical assembly makes and breaks circuits that are in communication with a remote site thereby indicating the status of the circuit breaker.

International Classification:

H01H 7500

US Classification:

335 16

Abstract:

A circuit breaker includes a first section and a second section with independently operating pairs of contact assemblies in each respective section. In the first section, at least one of the contact assemblies is constructed and arranged to interrupt the current by moving from a normally closed position to a blown-open position and latching with the contact assemblies separated. The second section has a biasing extension spring for biasing the contact assemblies of the second section so as to permit interruption of the current in response to a blow-open force, which causes the contacts to separate only momentarily and then return to a normally closed position. The first and second pairs of contact assemblies separate substantially simultaneously in response to the blow-open force, and only the first section reacts to lower-level over-current conditions. In addition to the contact assemblies, the second section of the circuit breaker is designed to operate using only a spring which is "Z-axis" mountable. Other aspects of the invention include one-piece tripping actuator, a screw retainer assembly for securing the line or load terminal, a bimetal arrangement involving an improved calibration process and an associated stress-reducing line terminal.

International Classification:

H01H 7500

US Classification:

335 16

Abstract:

A high current capacity blade for a circuit breaker, comprises a conductive blade body having front and rear sections connected to one another, where the rear section includes a surface attachment area for fastening a flexible connector of the circuit breaker thereto. A strain relief tang extending from the rear section of the blade body is used to engage the flexible connector so as to stabilize the fastening of the flexible connector to the surface attachment area. A broad conductive lateral section is connected to and extends laterally from the front section, and includes a blade tab for engaging a toggle spring of the circuit breaker. A broad moveable contact is mounted on the broad lateral section and is adapted to interface with a stationary contact of the circuit breaker. A pair of substantially parallel L-shaped blade legs are spaced from one another to permit the toggle spring to pass therebetween. Each of the blade legs has first and second ends with the first ends connected to the rear portion of the blade body and the second ends including respective blade pivots for engaging notches in a handle of the circuit breaker.

Assignee:

Square D Company - Palatine IL

International Classification:

H02B 101

US Classification:

361627

Abstract:

The present invention provides a mounting system for circuit breakers in an electrical panelboard assembly. The base and cover forming the circuit breaker casing has an integral foot extending from a bottom side. The foot is angled and has a notch on a side forming an acute angle with the bottom. The panelboard assembly has a bus cover adapted with a opening or opening to receive the foot. This secures the circuit breaker on one end, and a screw into a bus secures the circuit breaker on an opposing end. The bus cover has a rail which engages the notch in the foot. On an opposing side of the foot, a spring engages the foot and forces the foot into the rail. The spring is an integral part of the bus cover and is cantilevered at an angle to the main body of the bus cover. Ledges are formed integrally into the bus cover on opposing sides of the spring. The ledges prevent overstressing the spring while inserting the foot during installation of the circuit breaker.

Abstract:

An accessory module for monitoring and controlling the status of a circuit breaker. The accessory module attaches to the side of a circuit breaker and has a mechanism similar to the mechanism in a circuit breaker. The mechanism has multiple positions that correspond to multiple states of a circuit breaker Actuators transform relatively large-scale motions of the mechanism into small-scale motions and transfers these to buttons on switches. Depressing these switches depending on the position of the mechanical assembly makes and breaks circuits that are in communication with a remote site. A circuit board designed specifically to hold and locate the switches and actuators and provide tracings that can withstand high currents. The invention further provides a terminal plug having a pull tab which can be grasped to remove an otherwise inaccessible terminal plug. A dual-function base, which serves both as an enclosure and as a spacer.
