Product FAQs
5 answersWhat distribution equipment is compatible with the Siemens CFD63B200?
This unit-mount, bolt-on breaker is designed for installation in Siemens Sentron P1, P2, and P3 panelboards. It can also be integrated into compatible Siemens switchboards, motor control centers, and standalone enclosures.
What wire sizes do the terminal lugs on the CFD63B200 accept?
The standard lugs accommodate copper wire from 6 AWG up to 350 kcmil, and aluminum wire from 4 AWG up to 350 kcmil. Ensure all connections are torqued to the manufacturer specifications printed on the breaker label during installation.
Are the trip settings adjustable on this breaker?
The CFD63B200 features a thermal-magnetic trip unit with a fixed long-time thermal setting for standard overload protection. However, the instantaneous magnetic trip is adjustable, allowing electricians to customize the short-circuit response based on specific load and coordination requirements.
Is the Siemens CFD63B200 a current-limiting breaker?
Yes, it is classified as a current-limiting circuit breaker. During a severe short circuit, it acts rapidly to reduce the peak let-through current and limit let-through energy, which provides enhanced protection for downstream devices and reduces thermal and mechanical stress on the system.
Can the CFD63B200 be installed in direct current (DC) systems?
Yes, this breaker is rated for both AC and DC applications. For DC systems, it supports a maximum voltage of 500VDC and provides an interrupting capacity of 50 kA.
