SCT-013-000 Non-Invasive AC Current Clamp Sensor, 100A, Split-Core

Stepping up from the 30A version in the same SCT-013 family, this 100A split-core current sensor clamps around an existing conductor the same non-invasive way, letting current monitoring be retrofitted onto a higher-current circuit - a sub-panel feed, a larger appliance circuit, or a small commercial installation - without needing to cut and splice into the live wire.

The split-core ferrite design and basic sensing principle match the smaller 30A version: the core senses the magnetic field generated by current flowing through the clamped conductor and outputs a proportional signal, with output available in both current and voltage form (voltage output built in via an onboard sampling resistor), giving some flexibility in how the signal gets read by a downstream monitoring device. Frequency range is rated from 50Hz up to 150kHz, considerably wider than the basic 50/60Hz mains frequency, giving headroom for measuring current with some harmonic content rather than just a clean sine wave.

Construction again pairs a ferrite core with an ABS external housing, rated for 6000VAC dielectric strength for one minute and meeting UL94-V0 flame retardancy, both meaningful safety specs given the clamp sits around a live, potentially higher-current conductor than the 30A version. Non-linearity is rated within 3 percent across the 10-120 percent rated-current range, and the sensor includes a 1 meter output cable terminated at a 3.5mm plug.

Builders and electricians working on energy monitoring for a higher-current circuit - a sub-panel feed, a larger piece of equipment, or a small commercial energy-logging install - will find the SCT-013-000's 100A rating a well-matched step up from the smaller current-clamp versions in the same product family.
