Product Description
The Mersen / Ferraz Shawmut 2CL20BF is a cable limiter for 2/0 AWG copper cable (or 2/0 AWG aluminum), bf - blade to offset bus termination, rated 250 V AC.
A cable limiter protects one cable in a parallel run on service entrances and feeders: if that cable faults it opens and isolates it, while the other cables keep the load in service. It has no ampere rating and gives no overload protection; it is chosen by the cable size it is crimped to.
Interrupting rating: 200 kA AC. Approvals: Self-certified.
