High-current protection with 2000A amperage rating and 120/208V operation enables direct integration into heavy-duty switchgear, reducing the number of devices needed and lowering installation cost. The result is tighter fault coordination and more compact switchgear footprints, ideal for large distribution panels and motor control centers. Bottom feed fuse configuration simplifies wiring in retrofit scenarios, cutting installation time and minimizing field errors while maintaining robust protection in tight panel spaces. Arc Energy Reduction Relay and matched CTs included support enhanced arc management and accurate current sensing, improving worker safety and enabling faster protection tripping in demanding production environments. Three-pole, three-wire design delivers predictable trip coordination across three-phase systems, reducing miscoordination risks and easing panel wiring. UL Listed certification confirms safety compliance for industrial facilities, supporting code adherence and supplier reliability. A built-in control power transformer further simplifies control circuitry, helping reduce cabinet space requirements and installer effort while delivering consistent protection for low-voltage control systems.

FAQs
SCB2033B120208E is designed for three-pole, three-wire configurations with bottom feed. It supports 120 V control voltage and 208 V system voltage, making it suitable for many low- to medium-voltage switchgear applications. When retrofitting, verify panel dimensions and clearance for the 16 in length, 24 in width, and 28 in height, and plan for wiring routes to accommodate the bottom-feed design and installed CTs.
Key specs include a 2000A amperage rating, 120 V control voltage, 208 V operating voltage, bottom feed fuse configuration, and three-pole / three-wire construction. The unit also includes an Arc Energy Reduction Relay and matched current transformers, which improve safety margins and measurement accuracy, essential for reliable protection in demanding industrial environments.
Yes. The product is designed for 208 V applications with a three-pole, three-wire configuration. It pairs well with 208 V distribution panels and MCCs, providing robust protection for three-phase circuits and simplifying coordination with other protective devices in the same control scheme.
The SCB2033B120208E is UL Listed, which validates safety and compliance with common electrical codes for industrial equipment. This certification supports easier procurement by compliance-minded buyers and reduces risk during audits and inspections in manufacturing, data centers, and process facilities.
Maintenance focuses on ensuring the arc protection components remain intact and CTs retain accurate sensing. The included Arc Energy Reduction Relay and CTs simplify ongoing protection performance, potentially reducing downtime during faults and enabling longer service intervals. While initial cost may be higher, the protection reliability, streamlined installation, and UL-listed safety can lead to lower lifecycle costs and better total cost of ownership.
