ABB OT80FT4N2 Switch-Disconnector Assembly Unit

ABB OT80FT4N2 is a 4-pole, front-operated, door-mounted switch-disconnector designed to isolate a circuit in low-voltage switchgear. With a nominal current rating of 80 A and a rated insulation voltage Ui of 750 V, it supports up to 750 V operation and withstands impulse voltages up to 8 kV (Uimp). The unit uses screw-type terminals and accepts conductors from 1.5 to 35 mm², and it weighs about 0.35 kg with approximate enclosure dimensions of 70 mm wide, 72 mm high, and 69 mm deep. It is a non-fusible disconnect suitable for application in ABB’s SwitchLine family, with front-door mounting and no handle or shaft included; the handle and shaft are intentionally not supplied. The product is cataloged as 1SCA105499R1001 and is associated with IEC standards, with regional listings also referencing UL 508 and CSA C22.2 No. 14. Typical applications include isolating a downstream circuit within electrical panels and enclosures, service points, or control cabinets where a compact, front-access disconnect is required, and the 4P arrangement provides four separate poles for efficient isolation of multi-conductor circuits.
