FAQs
Plan for a three-pole, bottom-feed installation using the 2NO/2NC auxiliary contacts and the phase-failure relay. Verify panel clearances, wire routing, and bottom-fed fuse blocks to minimize wiring length. Ensure control voltage of 120 V and system voltage of 208 V match your MCC or distribution panel specifications, and confirm enclosure rating aligns with the operating environment.
This switch is rated for up to 3000A, with a system voltage of 208 V and a control voltage of 120 V. It features 2 normally open and 2 normally closed auxiliary contacts, a bottom feed configuration, and fusible protection. These ratings support high-current interlocks in demanding industrial applications while enabling straightforward interconnection to standard control circuits.
Yes. The three-pole design, bottom-feed configuration, and 3000A rating make it well-suited for motor control centers and power distribution panels. The unit’s UL Listing and NEMA compatibility (1, 3R, 4, 12) help ensure safe operation in a range of environments, while the phase-failure relay and SPVR provide additional protection for critical loads.
The CB3033B120208RACT7 is UL Listed, which supports compliance with widely adopted electrical safety standards. It also carries NEMA compatibility ratings (1, 3R, 4, 12), enabling safe operation in diverse enclosures. These certifications simplify audit processes, vendor qualification, and can streamline installation approvals in regulated facilities.
