Product FAQs
5 answersIs the Eaton K3100T fully compatible with legacy Cutler-Hammer panels?
Yes. Because Eaton acquired Cutler-Hammer, the Eaton K3100T is structurally and electrically identical to the original Cutler-Hammer K3100T. It will mount seamlessly into existing Cutler-Hammer K-frame panelboards and switchboards.
How does the thermal-magnetic LI trip function operate on this breaker?
The LI (Long-Time and Instantaneous) trip unit uses a bimetallic strip for thermal protection against sustained overloads and an electromagnetic assembly for instantaneous tripping during severe short circuits.
What are the installation benefits of the bolt-on connection on the K3100T?
The bolt-on design fastens the breaker directly to the panel busbars. This creates a highly secure mechanical and electrical connection that resists loosening in high-vibration industrial environments, reducing the risk of arcing.
Can this 3-pole breaker be used in a single-phase application?
The K3100T is designed for three-phase systems. While 3-pole breakers can sometimes be adapted for single-phase loads by leaving one pole unused, you must consult a licensed electrician and local electrical codes to verify compliance for your specific panel.
What safety checks are required after installing the K3100T?
A licensed electrician should verify that all bolt-on connections to the busbars are torqued to the manufacturer specifications. Proper torque prevents overheating and ensures the thermal-magnetic trip unit operates safely under load.
