Why RTS03?

Russelectric® RTS03 bypass/isolation automatic transfer switches deliver dependable source transfer and safe serviceability for mission‑critical facilities. Built to UL‑1008 standards with 3‑cycle closing and withstand ratings, RTS03 ensures robust performance under high fault currents and works with any manufacturer’s instantaneous‑trip circuit breaker. Its bypass/isolation design and positive mechanical interlocks allow maintenance without disrupting power, while intelligent controls provide precise timing and logic.

Available configurations

  • Open‑transition RTS03 – quick break‑make operation for standard applications
  • Closed‑transition RTS03 – momentary paralleling to avoid load interruption during retransfer or testing
  • Bypass/isolation models – enable safe isolation and continuous load support during service

Key benefits

Maximize uptime with seamless transfers

Choose closed transition to avoid interruption during tests or retransfer so sensitive loads stay online in healthcare, data center and industrial environments.

Simplify maintenance with safe bypass isolation

Bypass/isolation construction and positive mechanical interlocks let teams isolate and de‑energize the switch while keeping loads on a live source for safer, faster service.

Strengthen resilience with proven UL‑1008 ratings

3‑cycle closing and withstand performance supports high fault‑current applications; coordinate with current‑limiting fuses for ratings up to 200 kA at 480 VAC.
