£190.51
The ABB OT160G3-4BSN2 (SKU: 1SCA162528R1001) is a premium 4-pole switch disconnector engineered to provide safe, dependable electrical isolation for industrial machinery, OEM equipment and low-voltage power distribution systems. Part of the trusted ABB OT Plus switch disconnector range, it combines robust switching performance, compact dimensions and flexible installation for demanding industrial applications.
Designed for base plate or DIN rail mounting, the OT160G3-4BSN2 features integrated screw terminals with front IP20 terminal protection for safe, efficient installation. It is supplied with a direct-mounted, padlockable knob handle and supports optional external shaft operation where remote switching is required. The fourth pole is positioned on the right-hand side (N2) and supports both simultaneous switching and late-break/early-make operation.
With a rated operational current of 160 A, a 4-pole configuration and a rated operational voltage of up to 800 V AC, the OT160G3-4BSN2 is ideal for isolating three-phase systems with neutral in industrial automation, motor control centres, switchboards and commercial power distribution applications.
Switch disconnectors provide a visible and dependable means of isolating electrical circuits before maintenance, servicing and equipment replacement. The ABB OT160G3-4BSN2 safely isolates all three phases together with the neutral conductor, helping improve personnel safety while reducing operational downtime.
Its compact G3 frame, robust switching mechanism and flexible fourth-pole configuration make it particularly suitable for industrial control panels, OEM equipment and modern power distribution systems where reliability and safety are critical.
