Electrical motors might be called the “quarterback” of industrial activity. Intelligent motor protection relays can be considered the protective defensive line for monitoring, calculating and communicating potential overcurrent or overload conditions. Motor protection is used in residential (e.g., HVAC), commercial, and industrial facilities. Electrical professionals need to thoroughly understand the basic principles of motor protection…
Getting control of inventory, coordination, code compliance and workplace safety. The complexity of short circuit protection has grown due to increased safety requirements. The major industry regulations and standards that that must be observed are OSHA, NFPA 70E®, CSA-Z462, IEEE Standard 1584, and NFPA 70®: National Electric Code®. Technology has also improved, providing for better…
Traditional fuses are designed to limit threats to people and property by protecting your electrical system from overheating, fire and arc flash. But increasing safety requirements have created an immediate need to reduce the potential for arc flash even further. OSHA, for example, uses the new requirements of NFPA 70E to judge whether an employer…
Its a question we hear often – “Is it a contactor or motor starter”? This question is understandable since contactors and starters both control electric motors and many people use the two terms interchangeably, which can lead to a little confusion. The mechanical elements of starters and contactors are identical. Coil, contacts, arc chutes…and both devices…
