FAQs

CB1233T120208GRAX is designed for top-feed installation in industrial panels and switchgear with compatible NEMA ratings (1, 3R, 4, 12). Its dimensions (16 in depth, 24 in width, 28 in height) and 180 lb weight inform mounting hardware and clearance. Ensure enclosure supports fusible protection and allows space for auxiliary contacts or optional ground fault devices.
The switch is rated for 1200 A with a 208 V system voltage and 120 V control voltage. This enables robust protection for high-load feeders while coordinating with plant control power. The device also supports maximum operating voltage of 208 V and 120 V control circuits, aligning with typical industrial power distribution schemes.
The SPVR capacitor trip device provides a capacitor-coordinated, rapid protection mechanism that reduces nuisance trips while ensuring fast isolation of faults. It is particularly valuable in single-phase protection for feeder circuits and motor starters, helping maintain uptime in distribution panels and motor control centers where precise trip timing is critical.
Yes, CB1233T120208GRAX is UL Listed, meeting recognized safety standards for electrical switching devices. This certification simplifies procurement by ensuring the unit complies with common regulatory requirements, reduces risk during audits, and supports safer installation in general purpose and harsh environment panels alongside existing NEMA compatibility.
Key maintenance considerations include periodic inspection of fuse configurations and ground fault options, verifying SPVR operation, and ensuring tight connections for the top-feed terminals. Regular checks help prevent nuisance trips and extend contact life. The unit’s 120 V control circuit and 208 V system voltage should be validated during commissioning to ensure proper coordination with control power supplies.
