Description
The Fluke i40s-EL3X/3PK is a pack of three clamp-on current transformers designed for low current work up to 40 A. Its compact jaws close around conductors up to 15 mm in diameter and are accurate enough for measuring on the secondary side of 1 A and 5 A metering current transformers. Supplied as a matched set of three, the clamps suit three-phase connections to power loggers and analyzers, letting technicians capture all phase currents in metering cabinets without interrupting the circuit.
Key features
- Measurement range up to 40 A
- Accurate on 1 A and 5 A CT secondary circuits
- Jaw opening for conductors up to 15 mm diameter
- Supplied as a pack of three clamps for three-phase use
- Non-intrusive clamp-on measurement
Typical applications
- Measuring CT secondary currents in metering and protection panels
- Three-phase low current logging with power loggers
- Checking small loads and control circuits
- Energy monitoring where primary conductors are not accessible
