SYMAP®ARC

SYMAP®ARC

SYMAP®ARC is a protection system that detects an electric arc caused by a short circuit through an optical sensor and the load current input on the system to ensure the fast clearance of arc faults on an electrical system with short tripping time (< 2ms).

Arc protection system for low and medium voltage applications

  • modular, expandable system with easy DIN rail installation
  • stainless steel housing for high EMC safety
  • simple system: tripping only with light criteria
  • complex system: arc detection and tripping, current rate of change detection (di/dt), zone and cable compartment selectivity
  • protects human life
  • reduces damage impact
  • improves availability of vessels or plants

Master module
ARC-MS Master Simple module providing trip contacts and interlink to connect light detection modules
ARC-ME Master Extended module providing trip contact, current measurement and interlink to connect light detection modules. Optional HMI and quenching device
Light detection module
ARC-LS3T Up-to 3 Light Sensors and one fast Tripping output
Optional module
ARC-HMI Human Machine Interface to operate the extended arc protection system
ARC-IGN-A IGNition module including system cable to operate external quenching device
Light sensors
ARC-LLS Light Line Sensor length: 10/15/20/25m active sensor part is 5 m less
ARC-LPS Light Point Sensor length: 3/5/10m intermediate sizes available
