Effective Protection and Isolation is at the very heart of good electrical engineering. IMO offers a comprehensive range of modular low-voltage devices to provide protection from Over-Current, Short-Circuit and Earth Leakage faults, alongside power Isolation. Our MCB range includes standard 10kA and 6kA devices, alongside miniaturised single module 1+N units rated at 4.5kA. The full range of standard trip-curves and current ratings is available, along with the possibility to create customised trip-curve and current options. Offering protection from both Over-Current and Short-Circuit they are ideal for protecting equipment and wiring from high current situations. The IMO range of miniature circuit breakers have beendesigned for protection of electrical installations againstoverload and short circuits and are manufactured inaccordance with IEC 60898-1 Technical Data • Handle central-tripping function for circuit fault indicating • New front design; cover and handle in arc shape • Contact position indicating window; transparent cover to carry label • High short circuit capacity • Suitable for terminal and Pin/Fork type busbar connection • Finger protected connection terminals • Handle padlock device Tripping characteristics in accordance with B, C and D type curves • Curve B: 3-5 In • Curve C: 5-10 In • Curve D: 10-20 In Certification: B4: Semko / CE B10: VDE / Semko / CE
