ABB 1SCA105332R1001 Electrical Disconnect Switch

ABB 1SCA105332R1001 OT63F3 is a three-pole, front-operated disconnect switch (switch-disconnector) designed for base mounting or DIN-rail mounting in low-voltage distribution panels. This non-fusible device provides a clear isolation point for three‑phase circuits and uses protected clamp terminals for secure wire termination; note that the handle and shaft are not included and must be ordered separately. Referred to by the alternate catalog number OT63F3, the unit is rated for 63 A, making it suitable for compact, modular installations in control gear, motor control centers, and distribution boards where reliable isolation is required. The OT63F3 family emphasizes a front-operable interface paired with flexible mounting options to fit various enclosure layouts, while preserving a compact footprint. The combination of base mounting and DIN-rail compatibility enables integration into many ABB-supplied or third-party enclosure configurations, with the 3-pole design ensuring simultaneous isolation of all conductors in a three-phase circuit. This part is commonly used in industrial automation and building management applications that demand a visible, accessible disconnect point for maintenance and safety.
