Engineered for industrial power systems, the Siemens FD62B200 is a 2-pole, 200A molded case circuit breaker providing dependable thermal-magnetic protection. Its interchangeable trip unit allows facility managers to adapt to changing electrical demands. Designed for seamless integration, this unit-mount breaker fits into Siemens P1 through P5 panelboards and motor control centers. It comes equipped with standard lugs. With a 35kAIC rating at 480V, it safely clears high-level electrical faults.
What panels and equipment are compatible with the FD62B200?
This FD-frame breaker is designed for use in Siemens P1 subfeed applications, as well as P2, P3, P4, and P5 panelboards. It is also compatible with Siemens switchboards and motor control centers.
What lug kit is standard for the FD62B200?
The standard line and load lug kit for this breaker is the TA1FD350A, which accepts 6 AWG to 350 kcmil copper wire or 4 AWG to 350 kcmil aluminum wire.
What is the difference between the Siemens FD62B200 and FXD62B200?
The FD62B200 features a fixed thermal and adjustable magnetic trip unit, allowing you to fine-tune the instantaneous short-circuit response. The FXD62B200 has a fixed thermal and fixed magnetic trip unit with no adjustability.
What is the practical benefit of the adjustable magnetic trip on the FD62B200?
The adjustable magnetic trip allows you to tune the breaker's instantaneous response to short circuits. This is particularly useful for coordinating with downstream breakers or preventing nuisance tripping from high motor inrush currents in industrial applications.
Does the FD62B200 provide ground fault or arc fault protection?
No. This is a standard thermal-magnetic breaker with long-time and instantaneous trip functions. It does not include integrated ground fault or arc fault protection.
