2. Utilization categories - Wikipedia

   en.wikipedia.org/wiki/Utilization_categories

   The utilization categories category for low-voltage switchgear defines the characteristic operating conditions for switchgear such as contactors, circuit-breakers, circuit-breaker-fuse units, contactor relays, etc. These devices are dimensioned for different electrical loads and for different operating conditions.

3. Contactor - Wikipedia

   en.wikipedia.org/wiki/Contactor

   The current rating of the contactor depends on utilization category. Example IEC categories in standard 60947 are described as: AC-1 - Non-inductive or slightly inductive loads, resistance furnaces; AC-2 - Starting of slip-ring motors: starting, switching-off; AC-3 - Starting of squirrel-cage motors and switching-off only after the motor is up ...

4. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire.

   In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .

7. Selectivity (circuit breakers) - Wikipedia

   en.wikipedia.org/wiki/Selectivity_(circuit_breakers)

   Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault. The purpose of selectivity is to minimize the impact of a failure on the network.
