The REH3100 is a rugged industrial circuit breaker designed for 480V three-phase systems. With a 100A rating and a 3-pole configuration, this bolt-on unit is built for maintenance, retrofit, and replacement projects where reliable protection and fast, secure installation are essential.
Why this matters: the three-pole design provides coordinated protection across all phases in a 480V system, helping to prevent phase imbalance and maintain stable power distribution. The bolt-on mounting enables secure, field-friendly installation with minimal panel modification, reducing downtime during maintenance or upgrades.
Ideal for: manufacturing floors, industrial control panels, data centers, and power distribution cabinets where dependable, easy-to-replace protection is required. Use cases include routine maintenance of legacy equipment, retrofitting panels to modern 480V three-phase standards, and straightforward replacements that keep critical systems online.
Compatibility and installation tips: always confirm fit and ratings using the part number REH3100 as your primary reference before ordering. Verify that the target panel supports bolt-on breakers of 3-pole, 480V, and 100A, and follow proper lockout/tagout procedures in accordance with local code. Check bus bar geometry and mounting clearance to ensure a seamless swap with existing gear.
Practical guidance: keep a small inventory of mounting hardware and spare breakers to minimize downtime. When upgrading, pair the REH3100 with the appropriate protective accessories and consult your switchgear manufacturer’s installation instructions for best results.
