1SCA151062R1001 ABB OXB630E3X2QB Automatic Transfer Switch 630A 4P

The ABB OXB630E3X2QB (article 1SCA151062R1001) is a TruONE automatic transfer switch that integrates the switching mechanism and controller in a single self-contained unit. It provides automatic source changeover across a wide input voltage range of 200 to 480 VAC (±20%), combining an open style ATS with delayed transition I-O-II operation and a Level 2 DIP controller. This configuration suits critical power installations where installation simplicity and high availability are both required.

Technical specifications:

• Series: OXB630E3X2QB
• ABB article number: 1SCA151062R1001
• EAN: 6417019813196
