FAQs
Yes. The CB1233B120480RA9 is designed for bottom-feed, three-pole configurations and three-wire setups, making it a straightforward retrofit for many low-voltage switchgear installations. Its fusible protection and SPVR option integrate with standard MCC and panel schedules, reducing conversion time and minimizing rewiring errors during upgrades.
The device delivers up to 1200A amperage with a 120 V control voltage and 480 V system voltage, supporting NEMA 1, 3R, 4, and 12 enclosures. Protection is fusible by design, with optional Ground Fault Relay. A capacitor trip device (SPVR) and BFD indicator lights enhance protection accuracy and trip visibility for reliable motor and line protection.
Ideal for industrial power distribution, motor control centers, and heavy machinery protection, including conveyors, pumps, and fans. Its three-pole, bottom-feed design suits harsh environments, while UL Listed and NEMA-rated enclosures ensure industry-standard compliance in manufacturing, water treatment, and process industries requiring robust single- and three-phase protection.
UL Listed certification confirms conformity with safety standards for electrical devices, while NEMA ratings indicate enclosure suitability for varied environmental conditions. These certifications help ensure compliance with national and regional electrical codes, facilitate safer installations, and support warranty and service agreements when upgrading or expanding critical power systems.
Customers benefit from durable construction, straightforward installation, and configurable protection options, which reduce downtime and maintenance costs. The SPVR and optional ground fault features help minimize nuisance trips, shorten diagnostic times, and improve system reliability, delivering measurable ROI through extended equipment life and safer, more predictable operation.
