Abstract
A miniature switchgear device 10, of the type used, for example, in power supply installation boards and consumer units, has a trip function for isolating an installation 52 from an electrical supply 50 depending on an electrical condition of the installation 52. The device 10 has a front face 14 configured to be accessible to a consumer during use. Means 62 are provided for generating a signal indicative of an electrical parameter of the installation 52 during supply of electrical current thereto. Means 16, 68, 70 are further provided for presenting an indication corresponding to the signal to the front face 14 for display to the consumer.
Claims24
A miniature switchgear device having a trip function for isolating an installation from an electrical supply depending on an electrical condition of the installation, the device comprising:
- a front face configured to be accessible to a consumer during use;
- means for generating a signal indicative of an electrical parameter of the installation during supply of electrical current thereto;
- and
- means for presenting an indication corresponding to said signal to said front face for display to the consumer.
A device according to any preceding claim, wherein a transducer is provided within the device for sensing the electrical parameter and generating said indication signal in dependence thereon.
A device according to any preceding claim, wherein the indication signal is such as to represent an absolute magnitude of the electrical parameter or a level thereof relative to a predetermined threshold.
A device according to any preceding claim, wherein the means for generating a signal is operative for generating signals indicative of more than one electrical parameter or more than one characteristic thereof.
A device according to any preceding claim, wherein the information provided to the front face is formatted so as to be detectable by a consumer operable receiving apparatus.
A device according to any preceding claim wherein the information is presented to the front face in the form of a plurality of point sources.
A device according to any preceding claim, wherein the device is provided with a detection function and/or a protection function for any or all of:
- residual current, line current, over-current, line voltage, over-voltage, under-voltage, temperature, earth leakage current, power measurement and power factor.
A device according to any preceding claim wherein the device is a miniature circuit breaker (MCB).
