Information About FXD63B250
The FXD63B250 is a Siemens Sentron molded case circuit breaker classified under the FXD family. It is built for three-phase electrical systems requiring dependable protection at higher current levels. The breaker incorporates a non-interchangeable thermal-magnetic trip unit that provides long-time overload protection and instantaneous short-circuit response. It is commonly installed in commercial and industrial distribution equipment where reverse-feed capability and standardized Sentron performance are required.
Key Features
- Sentron FXD Series Design: Built to Siemens Sentron standards for robust low-voltage power distribution.
- 250 Amp Continuous Rating: Suitable for feeder and main circuit protection in industrial and commercial systems.
- Three-Pole Configuration: Provides coordinated protection across all phases of three-phase circuits.
- Thermal-Magnetic Trip Unit: Combines long-time overload protection with instantaneous short-circuit response.
- 35 kA Interrupting Capacity: Designed to safely interrupt high fault currents at 480 VAC installations.
- Reverse-Feed UL Listing: Approved for applications requiring reverse-fed breaker configurations.
- Bolt-On Construction: Ensures secure mechanical installation and stable electrical performance.
The FXD63B250 delivers the reliability and precision required for high-capacity circuit protection in Siemens Sentron three-phase electrical distribution systems.
