ABB OT125FL3 3-pole 125 A front operated switch disconnector, Product ID 1SCA112372R1001, with extended busbar terminals for industrial circuit isolation, control panels and low voltage power distribution applications.
£199.14
The ABB OT125FL3 is a robust and compact 3-pole switch disconnector designed for safe manual isolation of electrical circuits in industrial control panels, machinery and low voltage power distribution systems. As part of the proven ABB OT Series, it provides dependable switching performance for panel builders, OEMs and electrical engineers requiring reliable circuit isolation.
This front operated, non-fusible switch disconnector is suitable for both base mounting and DIN rail mounting, offering flexible installation in control cabinets and distribution assemblies. Its extended busbar terminals on both sides make it particularly useful where busbar connection, grouped wiring or compact panel layouts are required.
With a 125 A current rating, 3-pole configuration and Product ID 1SCA112372R1001, the OT125FL3 is ideal for three-phase circuit isolation and industrial load break applications. The operating handle and shaft are supplied separately, allowing the installation to be configured around the enclosure depth and panel layout.
Switch disconnectors such as the ABB OT125FL3 provide a safe and dependable way to isolate electrical circuits during servicing, inspection and maintenance. By allowing the supply to be manually disconnected, they help protect personnel and equipment while supporting safe working procedures in industrial installations.
The OT125FL3 is especially useful in panel layouts where extended busbar terminals simplify connection and improve wiring flexibility. Its compact 3-pole format, front operation and DIN rail compatibility make it suitable for control panels, distribution boards and machinery where reliable isolation is essential.
