- Selection Advice
- New projects first choice: LC1N630M7N – perfect drop‑in replacement, better performance, affordable
- General industrial use: LC1D620M7C – higher reliability for automation and HVAC
- Severe duty: LC1F630M7 – frequent starts (>600/час), heavy load, высокая температура
- Critical/extreme environment: LC1G630M7 – offshore, high altitude, low temperature, maximum reliability
- Important Warnings
- Although LC1E is not fully discontinued, Schneider officially recommends LC1N for better supply continuity
- 630A contactors typically control ~315kW (440В) three‑phase motors; match load, duty cycle, and environment
- Use matched thermal relays: LRE630N (LC1E/LC1N) or LRD630 (LC1D/LC1F)
