CFD63B100 - 100A Circuit Breaker

CFD63B100 - 100A Circuit Breaker

When a facility depends on consistent power distribution, having the right circuit protection in place matters. The CFD63B100 100 Amp 3-Pole Molded Case Circuit Breaker is designed for commercial and industrial electrical systems that require a compatible Sentron CFD6 frame breaker with a 100-amp rating and high interrupting capacity.

This breaker combines a 3-pole configuration, fuseless current-limiting design, and a non-interchangeable trip unit in a compact package built for demanding electrical environments. With interrupting ratings of 200kA at 240VAC and 480VAC, along with 100kA at 600VAC, the CFD63B100 is suited for applications where substantial fault-current protection is required.

Whether you're maintaining an existing electrical distribution system, replacing a failed breaker, or supporting ongoing facility operations, finding a breaker that matches the original equipment specifications can help minimize complications during installation. The CFD63B100 is commonly used in switchboards, panelboards, motor control equipment, and HVAC systems where a compatible CFD6-frame breaker is required. Because it includes load-side terminals and is designed for 50/60Hz operation in environments up to 40°C (104°F), it fits the needs of many established commercial and industrial installations.
