Abstract: This disclosure is directed to techniques for protecting a sensor from a short to a power supply. According to one example consistent with these techniques, a circuit or device may include a sensor unit and a short protection unit. The sensor unit may generate at least one signal indicative of at least one measured property. The sensor unit may be configured to communicate the at least one generated signal via an output node coupled to the sensor unit. The short protection unit may determine whether the output node is electrically coupled to a power supply input. The short protection unit may, if the output node is electrically coupled to the power supply input, provide at least one auxiliary load between the sensor unit and the output node, and thereby protect the sensor unit to prevent the sensor unit from operating undesirably and/or to prevent the sensor unit from damage.

Abstract: A housing for a single-pole circuit breaker is disclosed. The housing includes two current path regions, each region having a first section configured to receive an electromagnetic protection device, a second section configured to receive a thermal protection device, a third section configured to receive an arc extinguishing device, and a fourth section configured to receive an operating mechanism device. Each first section occupies a substantial part of the available internal width of the housing, and is disposed between the respective third and fourth sections. Each second section occupies about half the available internal width of the housing.
