OT80F4N1 ABB 80 A 4-Pole Switch Disconnector Neutral Pole Left

Why Choose the ABB OT80F4N1 80 A 4-Pole Switch Disconnector?

The ABB OT80F4N1, order code 1SCA105419R1001, is an 80 A 4-pole switch disconnector designed for reliable switching and isolation in low-voltage electrical systems. As part of the established ABB OT switch-disconnector series, it provides compact, dependable switching for industrial machinery, control panels, distribution boards and OEM electrical assemblies.

The OT80F4N1 is a front-operated, base-mounted and DIN-rail mountable switch disconnector with protected clamp terminals. Its four-pole configuration incorporates the neutral pole on the left, making it suitable for applications where the neutral conductor must be switched together with the phase conductors. The switch is supplied without an external operating handle and shaft, allowing suitable ABB operating accessories to be selected for the installation.

With an open-air thermal current of 80 A and an AC-23A operational current of 75 A at 400–415 V AC, the OT80F4N1 provides dependable load-switching performance in a compact format. This model has been superseded by the ABB OT80G2-4BSN1, the corresponding 80 A 4-pole OT Plus switch disconnector with left-side neutral pole.

Key Advantages

• Compact 80 A 4-pole switch disconnector for industrial electrical systems.
• Neutral pole positioned on the left for four-pole switching applications.
• 75 A AC-23A operational current at 400–415 V AC.
• Front-operated design for straightforward integration into electrical panels.
• Supports both base mounting and DIN-rail mounting.
• Protected clamp terminals improve connection protection.

Reliable Four-Pole Switching and Isolation

Switch disconnectors such as the ABB OT80F4N1 provide a dependable means of manually switching and isolating low-voltage electrical circuits. The four-pole arrangement allows the neutral conductor to be switched alongside the phase conductors, making the device suitable for installations where complete four-pole isolation is required.

The OT80F4N1 combines an 80 A thermal current rating with strong AC-23A switching capability, compact dimensions and flexible base or DIN-rail mounting. For new installations or replacement requirements, ABB has superseded this model with the OT80G2-4BSN1 from the newer OT Plus range.

Typical Applications

• Industrial control panels and electrical cabinets.
• Four-pole three-phase and neutral circuit isolation.
• Low-voltage distribution boards and assemblies.
• Industrial machinery and production equipment.
• Motor and equipment isolation.
• DIN-rail mounted electrical systems.
• OEM machinery and control equipment.
• Replacement and maintenance of installations using ABB OT80F4N1 switches.
