Siemens A01FD62 U 240V 1P FXD HFXDB Circuit Breaker

Siemens Sentron A01FD62 is a 240 VAC Form C auxiliary switch (1NO/1NC) designed to mount with Siemens FD, FXD, and HFXD frame molded‑case circuit breakers to provide a dedicated status output for the main device. The catalog number A01FD62 represents a single auxiliary switch with two contacts—the normally open and normally closed paths—so you can signal both open and closed states to downstream control or indication circuits without altering the primary protection offered by the breaker. Rated for 240 VAC operation and intended for use with 250 A FD, FFC and FFF frame breakers, this accessory integrates into the Sentron FD-series assemblies to deliver reliable signaling across FXD and HFXD family installations. The A01FD62 is used in applications such as remote indicator panels, machine automation signaling, interlocking schemes, and control logic where breaker status must be monitored or annunciated. With Siemens’ engineering backing, the unit is a purpose-built companion to FD-series breakers, enabling straightforward integration into panel and automation designs while preserving the integrity of the protection system.
