Description

Expand the capabilities of your electrical testing equipment with the Fluke I400S AC Current Clamp. Designed to work as a companion to your oscilloscope or power quality meter, this tool allows you to measure up to 400 A AC without the need to break the circuit. This makes your testing process faster and more efficient in various industrial environments. Safety is a primary focus for this device. The I400S is the only current clamp available that carries a CAT IV 600 V / CAT III 1000 V safety rating, providing peace of mind during high-energy measurements. Its compact shape is engineered for maximum utility, allowing you to reach into tight spaces where larger tools might fail. For added user protection, the clamp features a soft, non-slippery overmold handle. This design helps prevent accidental contact with live wiring, ensuring a more secure grip during operation. Whether you are working with digital multimeters or portable oscilloscopes, the Fluke I400S provides the reliable AC current range extension required for professional electrical testing.
