Protective Apparatus & Devices
|
These are safety device for smooth and risk-free operation of electrical appliance. They range from circuit breakers to high voltage relay. Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions. Fuse protect electrical devices and components from over-currents and short circuits that occur in improperly operating circuits. The light curtain controller contains the user controls, supporting logic, status and diagnostic indicators, power supply, and output relays. Safety relay and control modules have wide applications in high current and high ac and dc voltage ratings. Protective relays and monitoring relays detect or monitor for abnormal power system conditions. They detect defective lines and apparatus, or other power system conditions of an abnormal or dangerous nature and initiate appropriate control circuit actions. Over-voltage relays trip when a voltage rises above the required point. Level transmitter are used to proportionate the electrical output to level input.
