Series KTU7 UL489 Molded Case Circuit Breakers

Versatile, convenient and space saving - for a variety of applications

Sprecher + Schuh's KTU7 series of UL Molded case Circuit Breakers are UL489 and CE listed for global applications. The current limiting circuit breaker provides fixed short circuit and overcurrent protection and offers high interrupting ratings for 2- and 3-pole devices from 0.5 to 30A. These Circuit Breakers are 100% rated up to 15A.

Accessories are intelligently designed to be field installed. The compact busbars and supply blocks reduce wiring errors and installation labor cost. Connection modules for the CA7 Contactors simplify wiring and can reduce the number of DIN rails required, compacting panel space even further.

Advantages

Small foot print saves panel space, just 45 x 102 x 85 mm, up to 50% smaller than traditional MCCBs.
Interrupt rating of 65kA at 480Y/277V may allow higher overall panel short circuit rating.
Up to 6 times higher interrupting rating vs. traditional miniature circuit breakers.

Ideal Applications

Feeder Circuits for small cabinets, distribution panels, branch circuit protection, transformers and heaters
Control circuits for control circuit transformers and power supplies
Industrial Heating applications
Air conditioning and refrigeration applications
