Equipment used to distribute power and protect other equipments and systems from current or voltage surges.

What are you looking for in Electrical Distribution and Protection?

Battery Isolators (16 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.

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.

Motor control center (MCC) buckets are motor control modules intended for a motor control center. They typically contain a circuit breaker and a motor starter/contactor, and may contain a transformer.
Learn more about Motor Control Center (MCC) Buckets

Motor Control Centers (MCC) are a modular assembly which motor control units called buckets are installed, each bucket is intended to control a motor. It acts as a central switchgear panel for the control of multiple motors in an industrial facility.

Resettable PTCs (14 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.
