LR3 48-3/710

The LR3 48-3/710 from Block is a LR3 480V series three phase line reactor. It reduces harmonics and thereby protects systems against costly downtimes. The well thought-out, completely redesigned structure of this line reactor allows fast and easy installation in even the tightest of spaces. The reactor range meets high safety and quality requirements for tough industrial use. It is designed for extended and improved reliability of variable speed drives and may other type of power conversion equipment. In addition of harmonic mitigation, the LR3 series provides limited protection of connected loads. It minimizes mains pollution, to reduce the reactive power components and charging currents in the DC link capacitor and to improve cos(phi). This can be used as line reactor, commutating reactor or PFC reactor. It approved by DIN EN 61558-2-20, IEC 61558-2-20, UL 506, CSA 22.2, cURus, cULus and EAC standards.
