International Classification:

H01H 9/00

US Classification:

200293, 200303, 200306

Abstract:

An apparatus including an electrical switching device to control current to a load and a second case arranged to substantially encapsulate the electrical switching device. The electrical switching device includes a first case; a plurality of contacts disposed in the first case; and an opening in the first case disposed to expose the contacts. The second case is arranged to duct a blast from the opening of the first case of the electrical switching device.

Filed:

Mar 1, 2012

Appl. No.:

13/410106

Inventors:

Randall B. Elliott - Tigard OR, US
Subramanian Muthu - Portland OR, US
David Bruno - Portland OR, US

Assignee:

LEVITON MANUFACTURING CO., INC. - Melville NY

International Classification:

G05F 5/00

US Classification:

700292

Abstract:

A networked lighting control device may include a switching device to control power to a load, a communication interface to couple the relay module to a control module at the relay panel, revenue-grade metering circuitry to monitor power flowing to the load, and a controller to control the switching device in response to inputs received at the communication interface and to transmit metrology data to the control module. A control module may include a mounting interface to mount the control module to a relay panel, a first communication port to receive first control inputs using a first protocol, a second communication port to receive second control inputs using a second protocol, a third communication port to control one or more relay modules mounted to the relay panel using the local communication format, and logic to translate the first and second control inputs to the local communication format.

Appl. No.:

13/534010

Inventors:

Randall B. Elliott - Tigard OR, US
David E. Burgess - Beaverton OR, US

Assignee:

LEVITON MANUFACTURING CO., INC. - Melville NY

International Classification:

G01R 31/327

US Classification:

324423, 324418

Abstract:

A method for determining an actuation delay time for an electromechanical relay includes capturing a current waveform of an energized coil, determining a time at which the actuation component begins to move by analyzing the captured current waveform, and calculating the actuation delay time for the relay based on the time at which the actuation component begins to move. A method for determining a state of a latching relay includes energizing the coil of the latching relay, capturing a current waveform of the energized coil, and determining the state of the relay by analyzing the captured current waveform.
