- Protection coordination: This unit provides magnetic only (short‑circuit) protection and must be used with an overload relay (على سبيل المثال. 3RU series) for complete motor protection.
- Breaking capacity matching: Selected based on system short‑circuit calculation; 200kA suits most industrial grids.
- الأسلاك: Screw terminals for copper/aluminum cables; observe cross‑section and torque specifications.
- Mounting space: Large frame size requires sufficient cabinet space.
- Upgrade recommendation: Some 3RV1 models are discontinued; 3VA2 series is recommended for new projects for advanced protection and communication.
- مُكَمِّلات: اتصالات مساعدة, alarm contacts available for motor status monitoring and control.
