ABB OT25F3C 1SCA104863R1001 I-0-II changeover switch disconnector 3P 25 A 690V

The ABB OT25F3C (article 1SCA104863R1001) is a 25 A manual change-over switch for transferring a load between two independent power sources. Operating on an open transition principle, the load is de-energised momentarily during the switching sequence before being connected to the new source. The operating handle and shaft are not supplied with the unit and must be ordered as separate accessories.

Technical specifications:

• Series: OT25F3C
• ABB article number: 1SCA104863R1001
• EAN: 6417019390062
• Rated current: 25 A
• Operation: Manual
• Transition type: Open transition
• Handle and shaft: Not included, must be ordered separately

Features and benefits:

• Manual operation gives the operator direct, hands-on control of source selection without the need for auxiliary power or control wiring.
• Open transition switching ensures both supply sources are never simultaneously connected to the load, preventing back-feed between circuits during transfer.
• 25 A current rating accommodates a range of load-transfer applications at light commercial or control-panel level.
• Handle and shaft supplied as separate items allow the installer to choose the actuator that best suits the panel depth and cutout requirements.

Applications:

• Manual changeover between mains supply and a standby generator in residential or small commercial premises.
• Dual-supply source selection in electrical control panels and distribution boards.
• Transfer switching in small industrial systems where a brief supply interruption during changeover is acceptable.
• Emergency backup switching in installations requiring manual source transfer at up to 25 A.
