Déscription

The CTR Series 5 A secondary current transformers offer a compact, cost-effective means of measuring primary current and providing a 0 to 5 A output pro-portional to the primary current being sensed. Models include solid-core, doughnut-style round current transformers that mount directly on a conductor and have 609 mm (24") leads standard. Square current transformers have mounting feet and terminals for panel mount applications. Split-core models offer the same means of providing a 0 to 5 A output in proportion to the primary current being sensed as their solid-core counterparts but with the additional ease of split-core installation, and come in a molded two-piece enclosure with a friction fit interlocking opening and terminals.
