Abstract: A generally rectangular, planar electrical overcurrent sensing device having a top major surface and a bottom major surface includes a patterned metal foil conductor defined along the top major surface. The metal foil conductor has a first electrode region at one end region, a second electrode region at an opposite end region, and a current-concentrating region extending between the first electrode portion and the second electrode portion. The device further includes a planar sheet of a composition which exhibits PTC behavior and which comprises an organic polymer having a particulate conductive filler dispersed therewithin. The planar sheet has a first major surface in thermal contact with the bridging portion and has an opposite second major surface. A third patterned metal foil electrode secured to the second major surface of the planar PTC sheet is sized and aligned with the current-concentrating region such that heat generated in the current-concentrating region from electrical overcurrent flowing through the metal foil conductor is transferred to the planar sheet exhibiting PTC behavior and reduces a control current flowing to said third patterned metal foil electrode. An insulation layer may be imposed between the patterned metal foil conductor and the PTC sheet layer, and in such case the third patterned metal foil electrode is divided into two conductive areas separated by a gap aligned with the current-concentrating region, thereby providing a four terminal device. Tin pellets may be included in the current-concentrating region to reduce a melting/fracture temperature thereof below a flaming temperature of the organic polymer sheet forming the PTC layer.

Abstract: An electrical protection device for protecting an operating circuit from overcurrent and having relay contacts in series between an electrical power supply and an electrical power load and having a relay coil in parallel across the electrical power supply in an on state. The protection device includes a single relay package having a frame, the relay coil, an armature mechanically actuated from a normally closed contact position to a normally open contact position when the coil is energized, a bimetallic wiper mounted to the armature, a wiper contact mounted to the bimetallic wiper and a normally open contact, a diode connected in series with the relay coil and the normally open contact to pass coil energizing current to the coil from the electrical power supply during the on state and to prevent backflow of coil energizing current to reach the electrical power load when power is first applied to the coil, a first coil lead connected to the relay coil and a second coil lead connected to an anode of the diode, a first contact lead connected to the wiper contact, and a second contact lead connected to the normally open contact. In the on state the relay coil is connected to the electrical power supply through the diode and causes the wiper contact to connect to the normally open contact to connect the supply to the load through the first contact lead and the second contact lead. In the off state the bimetallic wiper responds to an overcurrent in the power supply path by changing shape and moving the wiper contact out of connection with the normally open contact thereby disconnecting the load from the supply.
