£338.31
The ABB OT100F8 is a durable and reliable 8-pole switch disconnector designed for safe manual isolation of electrical circuits in industrial control panels, machinery and low voltage distribution systems. As part of the proven ABB OT Series, it provides dependable switching performance for panel builders, OEMs and maintenance engineers requiring secure circuit isolation.
This non-fusible switch disconnector is front operated and suitable for both base mounting and DIN rail installation, giving engineers flexibility when designing control cabinets and distribution assemblies. Its compact construction, protected clamp terminals and robust mechanical design make it ideal for demanding industrial environments where safety, reliability and serviceability are essential.
With a rated current of 100 A, an 8-pole configuration and a rated operational voltage of up to 750 V AC, the OT100F8 is suitable for multi-pole isolation requirements in machinery, switchgear and automation systems. The operating handle and shaft are supplied separately, allowing the installation to be configured to suit the panel layout.
Switch disconnectors such as the ABB OT100F8 provide a safe and visible means of isolating circuits during servicing, maintenance and installation work. By separating electrical loads from the supply, they help protect personnel and equipment while supporting safe working practices across industrial installations.
The OT100F8 is particularly useful where multiple circuits or conductors need to be switched together. Its 8-pole format, compact body and flexible mounting options make it well suited to control panels, distribution boards and machinery where space efficiency and dependable isolation are important.
