- Description
A 200/5 A, class 1 rear-side current transformer kit, the ABB 1SEP408149R0002 CT-ZLBM123-200/5-1-BB is built for the ZLBM123 Inline fuse switch disconnector frame and carries a 3.75 VA burden. Installed behind the switch, it scales the primary current down to 5 A so a standard ammeter or meter can read it directly. Net weight is 1.3 kg.

Selection Notes
Choosing the 200/5 ratio means sizing the CT to the switch's actual load current, not its maximum frame rating, so an oversized ratio loses meter resolution at normal operating currents. This kit is built for the larger ZLBM123 frame, which distinguishes it from the ZLBM00 CT kits in the same family and means the two are not physically interchangeable.
