Compact 1-Module (18المليمتر) Electromagnetic RCBO - Product OverviewProduct IntroductionThis 1-module (18mm wide) electromagnetic RCBO combines residual current protection (RCCB) and overcurrent protection (MCB) in an ultra-slim design, making it ideal for space-constrained installations while ensuring:
• Personnel protection (electric shock prevention)
• Fire prevention (leakage current detection)
• Circuit protection (overload & short-circuit protection)
Key Features1. Ultra-Slim 18mm Design• Space-saving: Single-pole width of just 18المليمتر (1 DIN module), enabling high-density panel layouts.
• Electromagnetic tripping mechanism: Faster response and higher durability compared to thermal-magnetic RCBOs.
2. Residual Current Protection (RCCB Function)• Type AC/A:ο AC: Trips on sinusoidal AC residual currents (standard loads).
ο A: Also detects pulsating DC leakage currents (e.g., from VFDs, SMPS, LED drivers).
• 30mA sensitivity: Complies with direct contact protection requirements (IEC 60364).3. Overcurrent Protection (MCB Function)• Dual protection:
ο Thermal (bimetallic strip): Time-delayed tripping for overloads.
ο كهرومغناطيسي (solenoid): Instant tripping for short circuits.
• Tripping curves:
ο Type B (3–5× In): For residential/light commercial loads.
ο Type C (5–10× In): For circuits with inrush currents (motors, transformers).
4. Enhanced Reliability• Anti-welding contacts: Special alloy materials withstand high short-circuit currents.
• Nuisance trip prevention: Isolated circuit design avoids false tripping from cumulative leakage or switching transients.
Applications• Residential/Commercial: Sockets, lighting, HVAC branch circuits.
• Industrial: Control panels, compact switchboards, motor feeders.
• Retrofit Projects: Easy replacement of existing 1P MCBs in tight spaces.
