Equipment used to distribute power and protect other equipments and systems from current or voltage surges.
Battery Isolators (15 suppliers)
Battery Isolators divide DC current so that it only allows the current to flow in one direction for each battery. This enables charging of more than one battery from a one power source without connecting the batteries together.

Bus Plugs (24 suppliers)
Busbars and Busways (250 suppliers)
Circuit Breakers (993 suppliers)
Condition Monitors and Fault Detectors (65 suppliers)
Condition monitors and fault detectors find faults in mechanical, electrical, optical or other systems before a system failure condition occurs. An example of a fault in an electrical system is an arching circuit breaker. An example of a fault in a mechanical system is a failed roller bearing. Both mechanical and electrical faults produce characteristic sounds, which can be detected using air or structure borne acoustic detection techniques.

Resettable PTCs (10 suppliers)
Resettable (polymeric or positive temperature coefficient - PTC) fuses are unlike traditional fuses that have to be replaced after a fault condition, this may not be necessary when using resettable fuses. The internal resistance of the component increases in response to an overcurrent or a short-circuit condition, limiting subsequent disturbances. After the fault condition is removed, the device cools and the internal resistance drops to nearly its initial value, permitting normal equipment operation to resume.
