Figure 1.2 Comparison of impact timing for systems with and without ARC protection
The ARCON 3G protection system is designed as modular system, so that flexible use in
different switchgears is ensured.
The ARCON 3G system provides following modules which can be used to establish
different protection levels and topologies:
ARC-LITE-3G
Master LITE unit providing trip and watchdog contacts and
communication link to connected modules.
ARC-MAIN-3G
Master MAIN unit providing current measurement for additional
tripping criteria, voltage measurement, trip and watchdog contact and
communication link to connected modules, HMI and Masterlink.
ARC-TMOD-1QD Tripping module to operate separate quenching device (ARC-AT).
ARC-DMOD-3SL Module for electrical arc detection via line sensor (ARC-SL).
ARC-MAIN-HMI
Human Machine Interface to display and control the Master MAIN.
ARCON 3G offers three different systems (levels) of arc fault protection:
1. ARCON 3G simple arc protection system (only light criteria for arc fault monitoring)
2. ARCON 3G extended arc protection system (light & current criteria for full personnel
and assembly protection)
3. ARCON 3G complex arc protection system (up to 5 extended systems communicating
over Masterlink)
