Four Elements for Four Channels
The Seeker+ records four current channels, and this set supplies a clamp for each — three phases plus neutral. Measuring neutral current directly, rather than calculating it, is what lets you see triplen harmonics returning on the neutral conductor and identify unbalanced loading that a three-element set has to infer.
On four-wire wye services, that fourth channel is often where the answer is. Overloaded neutrals, harmonic heating in shared returns, and unbalance that never shows up in phase readings all become visible when the neutral is measured rather than assumed.
Two Ranges in One Clamp
The TLAR-S measures 20 A and 200 A AC on an adjustable range, with a 200 A continuous operating limit. Accuracy is 1.5% of reading ±0.1 A on the 20 A scale and 1.5% of reading ±0.5 A on the 200 A scale, across a 40 Hz to 10 kHz frequency range. Phase shift stays at or below 3 degrees from 1–20 A, 2 degrees from 20–80 A, and 2.5 degrees from 80–200 A, which keeps power and power factor measurements dependable across the full load range rather than only at the top of the scale.
Because the 20 A scale holds the same percentage accuracy at low current, the clamp is well suited to lightly loaded circuits and residential feeders, where a 200 A-only probe would leave you reading noise. That also makes it a natural fit for neutral measurement, where currents are typically a fraction of phase current.
Built for Enclosures That Are Already Full
The clamp accepts conductors up to .59 in (15 mm), with an enclosure measuring 2.36 x 1.38 x 0.67 in. Four-foot probe leads and a 9-inch output cable, both rated to 600 V, give enough reach to route around existing equipment without crowding the recorder.
That footprint matters more with four clamps than three. In a panel where a full-size clamp will not close on a single conductor, fitting four of them is not a possibility at all — the TLAR-S makes four-channel measurement practical in spaces where it otherwise isn’t.
Safe Installation, No Downtime
As a clamp-style current transformer, the TLAR-S measures without direct electrical contact and without breaking the circuit, so there is no shutdown to schedule and no customer interruption to coordinate. It is rated to IEC 61010-1, 600V CAT III, with IP40 probes and an IP65 enclosure, and operates from 14°F to 131°F (-10°C to 55°C) — suitable for both a short study and a permanent installation.
