ABB OT16F3 Switch Disconnector

ABB Switch Disconnector (Model: OT16F3)

The ABB Switch Disconnector (Model: OT16F3) is designed to ensure reliable switching and disconnection of electrical circuits. It features a rated operational voltage of 750 V and a thermal current of 25 A. This switch disconnector is UL/CSA rated for 20 A at 600 VAC and offers different operational current ratings depending on the application, including 16 A at 500 V and 10 A at 690 V. The device provides strong protection with a rated impulse withstand voltage of 8 kV and a rated short-circuit making capacity of 0.71 kA at 690 V. It is also equipped with a rated conditional short-circuit current of 50 kA, making it suitable for demanding environments. The switch operates at a service frequency of 50 to 60 Hz and conforms to IEC 60947-3 standards. With a 3-pole design and an IP20 protection degree, the OT16F3 offers a compact solution with dimensions of 35 x 68 x 56 mm.
