400 Amps / 66 uH Current Limiting Reactor, P/N 6265CLR, Fault Current: 21000 Amps, inside an indoor enclosure

Product Overview

Current Limiting Reactors are used for line reactors, inrush current limiting, and surge current limiter applications. Current Limiting Reactors (CLR) develops a higher voltage drop across the CLRs when the current through the CLRs increases. Current limit reactors are gapped inductors intended to reduce the short circuit currents passing through the circuit breaker in the power system.

The photo of an open core and coil dry type inrush current limiter, part number 6265L is shown below. Three gapped inductors, P/N 6265L are required for one CLR application.
