Our online Sector catalog is updated regularly and designed to accommodate a diverse range of configurations, including:
- Sector MCBs: High-quality miniature circuit breakers available across standard single-pole lines—including the reliable Series E (SE6B to SE40B), SVMCB, and color-coded toggle collections (including red, blue, and brown indicator variations) scaling from 6A to 50A thresholds.
- Sector RCBOs: Comprehensive residual current breakers with overcurrent protection tracking popular single-module and double-pole lines—featuring the premium SVRCBO and high-capacity SSTA ranges built for targeted earth-leakage defense under modern Type A and legacy Type AC guidelines.
- Sector RCDs & Main Switch Incomers: Robust isolation gear, featuring double-pole residual current switchboards scaling from 25 Amp up to 80 Amp (including SVRCCB and legacy 606 series lines) paired with heavy-duty 63A and 100A double-pole main switch disconnectors fitted with distinct red or blue handles.
- Advanced Circuit Safety: Reliable fault tracking across varied breaking capacity benchmarks (standard 6kA and high-performance 10kA ratings), responsive 30mA and 100mA trip fields, and distinct tripping profiles (Curves B and C) engineered for robust electrical safety.
