| A breaker failure detection device for a direct current (DC) circuit breaker (200) is provided. The circuit breaker comprises a circuit breaking element (204) and a non-linear resistor, e.g., a surge arrester (205), connected in parallel. The breaker failure detection device comprises a current sensor (212, 213, 214, 215), for measuring a current commutating from the circuit breaking element (204), and a breaker failure detection unit (211). The breaker failure detection unit (211) is arranged for comparing the measured current to desired values and deciding that an internal commutation process of the circuit breaker (200) does not proceed as desired if the measured current deviates from the desired values. The present invention makes use of an understanding that an improved detection of breaker failures may be achieved by monitoring the internal commutation process of the circuit breaker. Further, a method of breaker failure detection is provided. | ||||||

| 48 | Circuit breaker grip means | US885431 | 1978-03-10 | US4151386A | 1979-04-24 | Roland Nicol, deceased; by Helen C. Nicol Robinson, executrix |
| A circuit breaker having a handle stop for restraining the handle in a "tripped" or central position after the circuit breaker is electrically tripped to mechanically and visually indicate the tripped position.Also, an actuator is supported within the case of the circuit breaker and pivoted by the linkage mechanism (only when the latter is electrically tripped). During manual opening and closing of the circuit breaker contacts, the linkage mechanism does not pivot the actuator.Pivoting of the actuator (upon electrical tripping of the linkage mechanism) causes the actuator to engage and activate an auxiliary switch.When the circuit breaker handle is moved to the "off" position from the "tripped" or central position, the linkage mechanism simultaneously releases the actuator and the auxiliary switch is deactivated. | ||||||

| An electric receptacle with ground fault protection characterized by an insulating rectangular housing adapted for mounting in a wall outlet box. The housing comprises opposite end and edge walls with front and rear sides open and with a transverse partition dividing a chamber formed by the ends and side walls into a pair of side-by-side compartments. Partition aperture means between the compartments and the first compartment communicating with the open front side and the second compartment communicating with the open rear side. Receptacle components are disposed in the first compartment and electronic components are disposed in the second compartment, and the components in each compartment are so disposed as to minimize the space requirements for the receptacle. The receptacle components include a contact arm which carries one contact for each of two pairs of contacts and the arm is movable between open and closed positions of the contacts and is operatively connected to a latch member releasably holding the arm in the contact closed position. Ground fault sensing means for monitoring the flow of current through the receptacle is provided for releasing the latch member, whereby the contacts on the arm are opened and closed sequentially. | ||||||
