Photo from CIGRE NO 319 Brochure 1: Circuit breaker Main Contacts (not part of the control circuit). 2: Mechanical operating mechanism that releases the energy to move the main contacts ( (open and close) (not part of the control circuit). pneumatic energy storage systems, this is an electric motor or a motor operated pump or compressor.
Energization releases the mechanism thereby closing the main contacts of the circuit breaker. Once the circuit breaker reaches the closed position, auxiliary switch contacts in the closing circuit open and de-energize the closing coils. Typically, there is only one closing coil in the control circuit.
Once the circuit breaker reaches the closed position, auxiliary switch contacts in the closing circuit open and de-energize the closing coils. Typically, there is only one closing coil in the control circuit. 6&7: Open coils: These are solenoid devices which are energized in the event of a valid opening signal being received by the circuit-breaker.
Circuit breakers, devices carrying out the protection func-tion against overcurrents, are divided into three families including miniature circuit breakers, molded case circuit breakers and air circuit breakers. Miniature circuit breakers available for use in direct current are series S280UC, S800S UC and S800 PV.
The switches or contacts monitoring the stored energy, therefore, perform the following functions: • Lock out the close operation if the circuit breaker does not have enough energy to close and re-open safely. • Lock out the open operation if the circuit breaker does not have enough energy to open safely.
