Current transformer or DIN rail meter PCE-LCTB 50/21 (30) Series for measuring AC currents up to 400 A
The DIN rail meter PCE-LCT 50/21 (30) is used when alternating currents in circuits are too high to be directly detected by measuring devices. The DIN-rail meter converts the primary current into a proportional reduced secondary current which can be processed by a measuring device. In addition, the rail-mounted meter protects connected measuring devices against high voltages. The DIN rail Meters PCE-LCT 50/21 (30) series can detect primary currents from 50 A to 400 A depending on the version and convert it to a 1 A or 5 A secondary current. In addition, you can choose between the accuracy classes 1 and 0.5.
