ABB OTM63F3C21D400C 1SCA151424R1001 Motorized ATS 3P 63 A 400V I-0-II

The ABB OTM63F3C21D400C (article 1SCA151424R1001) is a 63 A, 3-pole automatic transfer switch with motor-operated actuation for automated changeover between two power sources. Rated for 400 V supply, this self-supplied unit operates in a 1-0-2 transfer sequence - source 1, off, source 2 - and offers adjustable parameters to match site-specific switching requirements.

Technical specifications:

• Series: OTM63F3C21D400C
• ABB article number: 1SCA151424R1001
• EAN: 6417019818290
• Rated current: 63 A
• Number of poles: 3
• Supply voltage: 400 V
• Operating mechanism: Motor operated
• Transition type: Open transition
• Transfer positions: Type 1-0-2 (source 1 - off - source 2)
• Unit supply: Self-supplied
• Operating parameters: Adjustable

Features and benefits:

• Motor-operated actuation enables fully automatic source changeover without manual intervention
• Open transition (break-before-make) switching ensures the two supply sources are never bridged simultaneously
• Three-position 1-0-2 configuration provides a safe neutral-off position between source 1 and source 2
• Self-supplied design removes the need for a separate auxiliary power circuit
• Adjustable operating parameters allow site-specific tuning of transfer conditions and timing

Applications:

• Automatic changeover between mains supply and standby generator in commercial or industrial facilities
• Dual-source distribution boards requiring automated supply switching
• Critical infrastructure panels where continuous power availability across two feeds is required
• Backup power installations in manufacturing plants, commercial buildings, and essential services
