ABB OT800U03CP is an 800 A three-pole UL manual open-transition change-over switch with I-O-II operation for industrial, commercial and optional standby power source selection.
£3,459.86
The ABB OT800U03CP is a heavy-duty 800 A UL manual change-over switch designed for reliable switching between two electrical power sources in industrial, commercial and optional standby power systems. As part of the ABB OT Change-over Switches product group, this three-pole switch combines high-current switching capability with straightforward manual source selection.
The OT800U03CP provides open-transition I-O-II operation, giving a defined OFF position between the two source positions. This arrangement disconnects one source before the alternative source is connected, making the switch suitable for applications requiring controlled manual transfer between mains, generator or other independent electrical supplies.
With a three-pole 800 A UL98 general-use rating at 600 V, the OT800U03CP is engineered for demanding high-current installations. The switch is supplied with a black IP65 operating handle, shaft, bolt set for cable connection and phase separators, providing a practical package for integration into suitable switchboards and electrical enclosures.
Manual change-over switches such as the ABB OT800U03CP provide a controlled method of selecting between two electrical power sources. Its open-transition I-O-II operating mechanism provides a defined OFF position during transfer so that one source is disconnected before the alternative source is selected.
The OT800U03CP combines an 800 A UL98 general-use rating with three-pole switching and robust construction for demanding power distribution duties. Its IP65 operating handle provides clear I-O-II position indication, while padlocking and door-interlock functionality support secure isolation, operation and maintenance when incorporated into a suitable electrical enclosure or switchboard.
