ABB OTM125F3C21D400C 1SCA151420R1001 Motorized ATS 3P 125 A 400V I-0-II

The ABB OTM125F3C21D400C (article 1SCA151420R1001) is a motor-operated automatic transfer switch in open transition type 1-0-2 configuration, rated at 125 A and 3-pole. It transfers electrical load between two supply sources automatically, drawing its own operating power from the monitored supply at 400 V - no separate control supply is required.

Technical specifications:

• Series: OTM125F3C21D400C
• ABB article number: 1SCA151420R1001
• EAN: 6417019818252
• Type: Automatic transfer switch (ATS)
• Rated current: 125 A
• Number of poles: 3
• Switching type: Open transition, type 1-0-2
• Operation: Motor operated
• Self-supply voltage: 400 V
• Operating parameters: Adjustable

Features and benefits:

• Motor-operated drive enables fully automatic load transfer without manual intervention
• Open transition type 1-0-2 switching provides a distinct off position between source 1 and source 2
• Self-supplied unit draws control power directly from the monitored circuit, removing the need for an auxiliary supply
• Adjustable operating parameters allow the switch to be set to suit the specific requirements of the installation

Applications:

• Automatic changeover between main utility supply and standby generator in commercial or industrial premises
• Power continuity systems where two independent three-phase supply sources are available
• Three-phase distribution boards requiring automatic source selection at up to 125 A
• Installations where manual transfer switching is not practical or sufficiently fast
