The ABB REA101-AAA is an arc protection relay designed primarily for protecting medium and low voltage switchgear.It can quickly detect and respond to arc faults to protect personnel and equipment.Product details are as follows:
Operating voltage:110-240V AC.
Main functions:
Arc detection:Arc detection can be performed using either spooled or probe-type optical fibers,supporting both ring-type and radial sensor fibers.
Overcurrent protection:Provides three-phase overcurrent protection,which can be combined with arc protection criteria for accurate and rapid protection.
Output tripping:Equipped with two high-speed solid-state output relays for rapid tripping,and also features a relay output for tripping.
Circuit breaker failure protection:Provides circuit breaker failure protection,capable of direct tripping or signaling.
Self-monitoring:Features a self-monitoring unit that monitors the sensor fibers,operating voltage,and wiring between the central unit and expansion units.
Communication interface:
Two RJ45 ports for connecting expansion units.Two optical connectors are used for fast on/off signal transmission between central units.
Expandability:The REA101 can be used as a standalone main unit or in conjunction with REA103,REA105,or REA107 expansion units.The REA101 has two output ports,each capable of connecting up to five expansion units.Multiple REA101 units can be linked together via optical fiber or through REA105 expansion units.
