Product FAQs
8 answersWhat equipment is compatible with the CFD63B100 breaker?
This 3-pole breaker mounts in Siemens Sentron P1, P2, and P3 panelboards, as well as compatible switchboards, motor control centers, and standalone enclosures. It requires a bolt-on connection.
Is the Siemens CFD63B100 a current-limiting circuit breaker?
Yes, the CFD6 frame is a fuseless, current-limiting molded case circuit breaker. It is designed to quickly interrupt high fault currents, providing enhanced protection for downstream electrical equipment.
How does the trip unit operate on the CFD63B100?
It features a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. This allows electricians to fine-tune the instantaneous trip threshold based on the specific load.
How is the CFD63B100 installed in a panel?
This is a unit-mount, bolt-on circuit breaker. It fastens directly to the bus or mounting assembly using bolts, ensuring a secure and reliable connection in high-vibration or heavy-duty industrial environments.
Is the CFD63B100 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment. It also meets UL 489 standards for molded case circuit breakers.
Can I use aluminum wire with the CFD63B100?
Yes, the standard lugs are rated for both copper and aluminum conductors. When terminating aluminum wire, ensure you use the correct wire gauge (4 AWG to 350 kcmil) and apply an appropriate oxide inhibitor to prevent corrosion.
What frame family does the CFD63B100 belong to?
It is part of the Siemens Sentron FD Frame group, specifically utilizing the CFD frame type. This is useful to know when sourcing compatible accessories like shunt trips or auxiliary switches.
Can the CFD63B100 be used in DC applications?
Yes, in addition to its 600VAC rating, this breaker is rated for up to 500VDC with an interrupting capacity of 50kA. This makes it suitable for specific industrial DC power distribution systems.
