BR-150 Flexible Rogowski Coil – designed for engineers who need 10 000 A capability without the weight, heat or hazard of traditional iron-core CTs. The 150 mm split-core loop opens with one hand, closes with an audible click and grips conductors from 8 mm busbar stacks to 100 mm cables without ever breaking the circuit. Class 0.5 accuracy (±0.5 % from 1 A to 10 kA) is maintained across a 10 Hz–100 kHz bandwidth, so you can trust the same sensor for 50 Hz energy-consumption sub-metering, 20 kHz SiC-inverter ripple capture, or transient diagnostics on a VFD line. Because the coil is air-cored it draws zero power from the system under test, eliminates saturation and removes the lethal open-circuit voltage risk associated with conventional CTs. The lightweight, IP65-rated cable stays flexible down to –20 °C and can be ordered in any length or diameter—wrap it once around a cramped panel, loop three turns for extra sensitivity inside a furnace cabinet, or retrofit an existing switchboard in minutes. A choice of 4-20 mA, 200 mV or digital output plugs straight into power analyzers, data loggers, oscilloscopes or portable recorders.
