FAQs
CB2533T120208GRAX is designed for top-feed installations with three-pole, three-wire wiring and fusible protection. It fits standard switchgear footprints and supports optional auxiliary contacts and Kirk provisions. Ensure control voltage is 120 V and system voltage is 208 V; verify enclosure compatibility with the indicated NEMA ratings. Recommend verifying the grounding scheme and incorporating the ground fault transformer option where safety standards require it.
Key specifications include a 2500A amperage rating, 208V system voltage, 120V control voltage, and fusible protection with a single-phase SPVR capacitor trip device. It is a three-pole, three-wire configuration with top-feed. The device is UL Listed and compatible with NEMA 1, 3R, 4, and 12 enclosures, supporting reliable operation in varied industrial environments.
Yes. The 2500A rating, three-pole design, and SPVR capacitor trip device are specifically geared for high-current protection in motor control centers and switchgear. With 208V system voltage and a 120V control circuit, it integrates with standard motor starters and control systems while providing dependable fault protection and reliable tripping behavior.
The unit is UL Listed, ensuring compliance with essential safety standards. It supports NEMA-rated enclosures including NEMA 1, 3R, 4, and 12, which broadens its applicability across indoor and outdoor/potential exposure environments. Always confirm enclosure rating matches the operating environment and consider optional ground fault and blown fuse detection accessories for enhanced protection.
