Abstract

Examples described herein relate to circuit breaker reset for power distribution units (PDUs). In one example, an apparatus to reset a circuit breaker of a PDU includes a bracket to enclose a portion of a rack rail, where one end of the bracket is coupled to a surface of the PDU including the circuit breaker. The apparatus also includes an elongated member disposed within the bracket, the elongated member includes a distal end to make contact with the circuit breaker, when force is applied to a proximal end of the elongated member, to reset the circuit breaker.

First claim

What is claimed is:

1. A system, comprising:
a power distribution unit (PDU), the PDU comprising:
a plurality of power receptacles on a front surface of the PDU to distribute power to a plurality of electronic devices coupled to the PDU; and
a plurality of circuit breakers on an external back surface of the PDU, the plurality of circuit breakers corresponding to the plurality of power receptacles,
wherein the PDU is mounted on a respective one of rack rails; and

a circuit breaker reset member, comprising:
a bracket to enclose a portion of the rack rail, the bracket comprising a first end coupled to the back surface of the PDU and a second end coupled to the rack rail; and
a plurality of slide rails disposed within an inner portion of the bracket, each slide rail corresponding to the respective circuit breakers and each slide rail including a distal end and a proximal end, the distal end to make contact with the respective circuit breakers when force is applied to the proximal end, to reset the respective circuit breakers.

2. The system of claim 1 , the circuit breaker reset member comprising:
attachment pins for the slide rails to attach the slide rails to the circuit breaker reset member; and
cutout portions at the distal and proximal ends of the slide rails to receive the attachment pins and to limit motion of the slide rails in a horizontal direction when force is applied to the proximal ends of the slide rails.

3. The system of claim 2 , wherein the attachment pins limit a sliding motion of the slide rails when the cutout portions are stopped by the attachment pins within the cutout portions.

4. The system of claim 1 , the circuit breaker reset member comprising a plurality of spring members, a spring member disposed between the distal end of each slide rail and the back surface of the PDU, wherein each spring member maintains a minimum distance between the distal end and the back surface of the PDU to enable the circuit breakers to be tripped without interference by the slide rails.

5. The system of claim 1 , wherein the proximal end of each slide rail extends horizontally beyond the bracket to enable access to the proximal ends of the slide rails to apply necessary force to reset the circuit breakers.

6. The system of claim 1 , wherein the plurality of receptacles comprise a number of groups of receptacles, wherein each group of receptacles is associated with a circuit breaker of the plurality of circuit breakers.

7. The system of claim 6 , the circuit breaker reset member comprising visual indicators to align a group of power receptacles to one of the corresponding circuit breakers.

8. The system of claim 1 , wherein the plurality of receptacles comprise International Electrotechnical Commission (IEC) C13 or C19 receptacles.

9. The system of claim 1 , wherein the PDU is mounted between the respective rack rails of a rack enclosure.

10. The system of claim 9 , wherein the rack rails include Radio Electronics Television Manufacturers' Association (RETMA) standard rails.

11. The system of claim 1 , wherein the plurality of circuit breakers include a switch based circuit breaker or a push-rod circuit breaker.
