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.
Thermal Overcurrent Circuit Breakers
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.
Thermal-Magnetic Overcurrent Circuit Breakers
Ideally suited to protect against overcurrent and short circuit of equipment in telecommunications, process control and other industrial applications where sophisticated equipment requires a high precision performance.
A latching type bimetal is combined with a magnetic coil to ensure protection and genuine physical contact isolation. This provides the joint benefits of delayed operation for low level overcurrent protection and fast magnetic action of higher value short circuits, disconnecting the faulty circuit within milliseconds.
Hydraulic-Magnetic and Magnetic Overcurrent Circuit Breakers
Circuit breakers with magnetic or hydraulic-magnetic trip mechanism respond extremely fast and provide genuine physical contact isolation. Magnetic trip ensures disconnection of the faulty circuit nearly without delay in the event of short circuit, but also in the event of low overloads. Our models also provide hydraulically delayed switching characteristic required for certain applications.
