FAQs
CB2533B120208RARCT uses a bottom-feed fuse configuration and three-wire, three-pole design, simplifying wiring and reducing panel depth. Its footprint (17 in deep, 32 in high, 28 in wide) and weight (approx. 235 lb) require sturdy mounting; Kirk provisions and auxiliary contact options can ease integration into existing switchgear and interlock schemes.
The switch is rated for 2500 A with a 120 V control voltage and a 208 V system voltage, supporting three poles and three wires. It operates as fusible protection and is designed for single-phase protection with SPVR. Ground fault is not included by default, while enclosure compatibility includes NEMA 1, 3R, 4, and 12 ratings.
Yes. The CB2533B120208RARCT is UL Listed, ensuring compliance with safety standards. It is compatible with NEMA-rated enclosures including 1, 3R, 4, and 12, providing rugged protection for industrial environments such as manufacturing floors, outdoor fixtures, and dusty plant areas.
The SPVR, a single-phase voltage relay with capacitor trip device, coordinates rapid fault detection and timed tripping, reducing the risk of nuisance trips and minimizing arc flash exposure. This leads to shorter outage durations, improved equipment life, and enhanced safety in motor control centers and power distribution panels.
Eaton offers a warranty policy of 25-000 with one year from installation or 18 months from shipment, whichever occurs first. Support includes access to Eaton specification sheets and catalog resources, along with optional features like ground fault relays and auxiliary contacts to fit evolving protection schemes in service centers and OEM integrations.
