Ideally suited to protect against overcurrent and short circuit of a broad range of equipment and systems – from motors and transformer windings, through printed circuit boards, to the low voltage power distribution circuits of road vehicles, boats and battery powered machines.
The trip time of thermal circuit breakers depends on the overload current. The heating effect of current heats up the bimetal or hot wire until the tripping point is reached and the breaker provides genuine physical contact isolation.
Typical Applications of High Performance Circuit Breakers and Battery Isolation Switches.
High performance circuit breakers are ideally suited to protect against overcurrent and short circuit for use in aircraft and vehicles and other specialised equipment where safety is paramount. Battery isolation switches are ideally suited for installation in the main battery systems of heavy duty vehicles including tankers, boats, off-road plant and other battery-powered equipment.
High performance circuit breakers feature thermal or thermal-magnetic trip and an extremely high rupture capacity. Battery isolation switches are also based on a thermal-magnetic trip mechanism. The thermal part of the circuit breaker provides delayed protection in the event of overload, the magnetic part disconnects the faulty circuit in the event of overload or short circuit within milliseconds. All products of this group provide genuine physical contact isolation.
DC Disconnects or isolating switches are used for opening or closing a circuit, e.g. for plant maintenance and repair. In photovoltaic applications, the DC Disconnect helps to isolate the PV generator from the remaining electrical system. Arc fault detectors monitor systems and plants with regard to hazardous arcs. They detect arcs early in the formation phase and help to prevent fire hazard.
DC Disconnects are designed for switching under load conditions. Besides the manual actuation, additional functions are available such as motor actuation and undervoltage release which allow remote control of the DC Disconnect.
By means of a frequency analysis, arc fault detectors identify the characteristic frequency spectrum of arcs. After detecting an arc, they provide a tripping signal e.g. to a disconnect switch which quenches the arc by opening the circuit.
