— EntelliGuard ™ G low voltage power circuit breaker Functions

Optional Functions EntelliGuard ™ G Circuit Breakers offer many optional functions in order to enhance and facilitate the use of the circuit breaker. Those functions include: - Auxiliary Switches - (Optional) Four available designs: - Power rated (3NO+3NC) - Power rated (3NO+3NC) + low signal (Hi-Fi) (2NO+2NC) - Power rated (8NO+8NC) - Power rated (4NO+4NC) + low signal (Hi-Fi) (4NO+4NC) - Key Interlock - Up to four optional key interlocks are available (Kirk, Ronis, Profalux, Castell). Switchgear applications utilize a Kirk key interlock mounted in the cassette. A maximum of two key interlocks may fit in the cassette. - Mounting Straps/Accessories Kits - are available to mount and connect fixed/stationary breakers. - Optional Lockable Shutters - are available (factory installed). - Carriage Position Switch - This optional cassette/ substructure device permits local or remote indication of the circuit breaker status (CONNECTED, TEST, DISCONNECTED), 2NO/2NC single pole, double throw contacts are available for each position. - Lifting Truck - Optional lifting tool with separate slings is available for all breaker sizes. - Optional IP Covers - IP54 covers (protected against harmful amounts of dust and splashing water) are available for all breaker sizes. - Mechanical Counter - Provides local record of the cumulative number of complete breaker closing operations. - Cable Interlocks - (OEM Applications Only) Available for fixed and draw-out breakers, these units enable direct interlocking of EntelliGuard ™ G circuit breakers. - Bell Alarm Contact - Available with or without a mechanical lockout feature, the bell alarm operates when the trip unit issues a trip command.

EntelliGuard ™ G circuit breakers with EntelliGuard trip units can be part of an ArcWatch ™ solution. ABB’s ArcWatch ™ system solution involves a combination of intelligent trip units and current limiting molded case circuit breakers to create a no compromise solution; safety and reliability together. Advances in zone selective interlocking (ZSI) and waveform recognition algorithms allow entire systems to be designed so that full selectivity and 100% instantaneous protection at calculated arcing current is possible. For most industrial systems, the ABB ArcWatch ™ solution will result in incident energy under 8 cal/cm 2 at 18”. Enabling ArcWatch ™ means the proper coordination analysis techniques have been used to determine the necessary circuit breaker protection features and settings that allow full coordination in the given system. The circuit breaker must be set to match the results of the completed study.
