3-in-1 split-core current transformer | 5 A | 3-phase | 333 mV | RJ45 / RJ12 | 1 m cable | SCT-010 model | STP-5
Code: ESSTP-53-in-1 split-core current transformer designed for current measurement in three-phase electrical circuits. Three split-core current sensors are integrated into a single cable set, allowing fast and safe connection of all three phases without disconnecting the conductors. Thanks to the 333 mV output signal, RJ45 / RJ12 connectors, and compact design, the device is suitable for use with panel-mounted and DIN-rail power analyzers, especially where fast installation, neat panel layout, and measurement accuracy are essential.
