I400E 400A AC Current Clamp LULER 4mm Banana Plug for Multimeter 101

Description

Product Overview

The LULER I400E 400A AC current clamp is engineered for precise alternating‑current measurement in a compact, user‑friendly form factor. Featuring a high‑quality 4mm banana plug, the clamp integrates seamlessly with popular multimeters such as the Fluke 101, 15B+, and 17B+ series, eliminating the need for additional adapters. The clamp’s robust housing is constructed from die‑cast aluminum alloy, providing excellent resistance to impact, corrosion, and the rigors of daily field work. Internally, a calibrated Hall‑effect sensor delivers accurate current readings up to 400 A RMS, while the built‑in safety fuse protects both the instrument and the operator from overload conditions. The device is calibrated to meet IEC 61010‑1 standards, ensuring reliable performance across a wide temperature range from –20 °C to +50 °C. With a clear, backlit LCD display on the host multimeter, users can quickly read current values without ambiguity, even in low‑light environments. The clamp’s ergonomic design includes a non‑slip rubber grip and a lightweight profile, making it easy to attach to conductors of various diameters without compromising measurement integrity.

Usage

Designed for electricians, HVAC technicians, industrial maintenance crews, and serious hobbyists, the I400E clamp excels in a variety of real‑world scenarios. Whether you are troubleshooting a residential circuit, performing preventive maintenance on a manufacturing line, or calibrating equipment in a laboratory, the clamp provides fast, non‑intrusive current measurement. Its 4mm banana plug connection allows direct coupling to the multimeter’s input jack, reducing setup time and minimizing potential connection errors. The device is ideal for measuring motor start currents, transformer loads, and inverter outputs, as well as for verifying compliance with energy‑efficiency standards in commercial buildings. Because the clamp does not require the circuit to be opened, it enhances safety on live systems and reduces downtime. The rugged construction also makes it suitable for outdoor use, withstanding dust, moisture, and occasional drops that are common on job sites. Users appreciate the intuitive “clip‑and‑read” workflow, which speeds up diagnostic procedures and improves overall productivity.

FAQ

What multimeter models are compatible with the 4mm banana plug?

The clamp works with any multimeter that accepts a standard 4mm banana plug, including the Fluke 101, 15B+, 17B+, and most other brands that follow the IEC 61010‑1 standard.

Can the I400E measure DC current as well as AC?

While the device is optimized for AC current measurement, the Hall‑effect sensor can also detect DC currents; however, accuracy specifications are guaranteed only for AC up to 400 A RMS.

Is the clamp suitable for outdoor or harsh environments?

Yes. The aluminum housing and sealed internal components protect the clamp from dust, moisture, and temperature extremes ranging from –20 °C to +50 °C, making it ideal for field work.

What is the warranty coverage for this product?

LULER offers a one‑year limited warranty that covers any manufacturing defects. If the clamp fails due to a defect, you can contact our support team for a replacement or repair.

How do I ensure the clamp remains calibrated over time?

Periodic verification against a known reference source is recommended. LULER provides calibration services and can guide you through the process to maintain measurement accuracy.
