Circuit Protection Introduction Circuit Protection Introduction Any electrical or electronic equipment that is designed without including circuit protection is an accident waiting to happen. Under normal operating conditions, this may not appear to be a problem. However, normal operating conditions are not always guaranteed. Under strained or heavy use, a motor and/or another loadgenerating component within the equipment will draw additional current from the power source; when this happens, the equipment’s wires and/or components will overheat and may ultimately burn up. Also, power surges and...

Choices of Circuit Protection / Hydraulic/Magnetic Circuit Breakers Available Choices of Circuit Protection Carling Technologies offers three types of circuit protection devices: thermal circuit protectors, hydraulic-magnetic circuit protectors/breakers and equipment leakage circuit breakers. This catalog features hydraulic-magnetic circuit protection products. For details related to our thermal and ground fault circuit protection product lines, please visit our website. Thermal circuit protectors utilize a bimetallic strip electrically in series with the circuit. The heat generated by the current...

Typical Applications / What Makes A Magnetic Circuit Breaker Trip Typical Applications Magnetic circuit breakers protect wiring, motors, generators, transformers, solid state systems, computers, telecommunications systems, micro-processors, peripheral and printing devices, office machines, machine tools, medical and dental equipment, instrumentation, vending machines, industrial automation and packaging systems, process control systems, lamps, ballasts, storage batteries, linear and switching power supplies, as well as marine control panels and numerous other applications. Generally, wherever...

How Time Delays are Obtained / Available Circuit Options How Various Time Delays are Obtained Generally speaking, the trip time of a time delay magnetic circuit breaker is directly related to the length of time it takes for the moving metal core to move to the fully “in” position. If the delay tube is filled with air, the core will move rather quickly, and the breaker will trip quickly. This is characteristic of the Ultrashort Delay Curves #11 and #21. Solid state devices, which cannot tolerate even short periods of current overload, should use Instantaneous Curves #10, #20 and #30. These curves...

Available Circuit Options Continued Series Mid-Trip with Auxiliary / Alarm Switch Similar to “Series Trip with Auxiliary Switch” except the S.P.D.T. auxiliary switch is actuated only upon electrical trip of the breaker. Upon electrical trip, the “N.O” contact closes and the “N.C” contact opens. This can be used to remotely signal the “TRIPPED” status of the breaker. Also, upon electrical trip, the handle moves to the “MID” position as opposed to the “full OFF” position typical of other breakers. This gives a specific visual panel indication of a “TRIPPED” breaker as compared to one which is merely...

Shunt Trip Switch Only O— Line Terminal Same as a Series Trip, but without a sensing coil. Provides low cost, heavy-duty switch capability when overload protection is not needed. “Switch Only” is available with and without an auxiliary switch. Relay Trip A four terminal device in which the contact and coil circuits are electrically isolated but mechanically linked. An overload in the coil circuit will cause the contact circuit to open. These circuits may be of opposite polarity. Commonly used in dump circuit, panic circuit, and remote shutdown applications. (Note: World Approval Agencies may...

Regulatory Agencies / Warranty Most countries have regulatory agencies that determine the safety and performance standards required for products used in that country. Carling Technologies’ circuit breakers are tested and have been certified by the most widely recognized of the these agencies including Underwriters Laboratories (UL) in the United States; Canadian Standards Association (CSA) in Canada; TUV Rheinland/Berlin-Brandenburg (TUV) and Verband Deutscher Elektrotechniker (VDE) in Germany. UL Recognized / UL1077 Recognized UL Recognition covers components, which are incomplete or restricted...
