FAQs
The CB2033B120208E7 is designed for three-pole, three-wire protection in switchgear and motor control centers. Its bottom-feed configuration and fusible protection support clean wiring runs and compatible integration with common MCC architectures, while the included Arc Energy Reduction Relay and matched CTs simplify protective relaying and fault detection in existing protection schemes.
Key specs include a 2000 A amperage rating, a 208 V line voltage, and a 120 V control voltage. The device is fusible and UL Listed, with a three-pole, three-wire configuration that suits three-phase power distribution and ensures coordinated protection across feeders in industrial power systems.
Arc Energy Reduction Relay lowers the incident arc energy during faults, reducing arc flash risk to personnel and equipment. This improves overall safety in maintenance and emergency scenarios and helps facilities meet arc-flash reduction goals while preserving equipment integrity.
Plan for a 16 x 28 x 24 inch footprint with a 175 lb weight to fit typical switchgear enclosures. The bottom-feed design simplifies wiring, and the included control transformer aids seamless integration with existing control circuits. Ensure proper mounting, secure CT connections, and confirm UL Listed compliance for ongoing reliability.
Expect improved uptime due to robust protection against overloads and faults, safer maintenance through arc-energy control, and easier commissioning with matched CTs and a control transformer. The UL Listed certification supports faster procurement and compliance audits, while the high current rating reduces the need for frequent protective device refresh in demanding facilities.
