Strom St265 Subminiature Thermal Overload Relay High Power Motor Protection Electronics Earth Fault Indicatorsealed Relays

Strom St265 Subminiature Thermal Overload Relay High Power Motor Protection Electronics Earth Fault Indicatorsealed Relays. Self-Powered Design: Harnesses power from CT sensors, eliminating the need for DC panels or UPS systems. Multi-Stage Protection: Features three-stage phase-to-phase overcurrent and two-stage earth grounding protection. Sealed & Maintenance-Free: Robust sealed case with anti-interference capabilities for harsh environments. Wide Voltage Range: Rated power supports AC/DC 24V~230V, suitable for diverse power sources. Fast Tripping Algorithm: Adopts short-data-window fast algorithm for real rapid tripping of short-circuit faults. Compact Installation: Small size (214*100*156mm) ideal for ring-power-grid cubicles with tight conditions. Inrush Current Blocking: Prevents error tripping when operating transformers under no-load conditions. Patented Technology: System protected by multiple patents with high-integrated processor and digital logic.
