Siemens FXD62B070 Molded Case Circuit Breaker

This FD frame breaker is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards, as well as SB switchboards and Siemens motor control centers.

It features a unit mount, bolt-on connection type. It secures directly to the chassis or mounting pan using bolts rather than snapping onto a busbar.

While the thermal overload protection is fixed, the magnetic instantaneous trip can be adjusted. This allows electricians to tune the breaker to handle specific short-circuit inrush currents without nuisance tripping, which is especially useful for motor loads.

Yes, Siemens acquired ITE and continued the Sentron product line. An older ITE FXD62B070 is the exact same form factor and specification as the current Siemens branded version.

When applying this breaker in DC systems, electricians must ensure the load is properly distributed across the poles to safely extinguish DC arcs, as DC faults do not have a zero-crossing point like AC power.

Yes, this model includes standard mechanical lugs for wire termination. Always torque the lug screws to the manufacturer specifications printed on the breaker faceplate to prevent overheating.
