Siemens 5SU9304-1KK RCBO Series | 1-Pole + Neutral, 10kA, 30mA, 16A to 40A AC/A Type Compact Safety Switchgear

Siemens 1-Pole + Neutral 10kA 30mA RCBO Series (Model Code: 5SU9304-1KK) represents the ultimate evolution in combined lifecycle electrical protection. By integrating miniature circuit breaker (MCB) overcurrent engineering with highly sensitive residual current device (RCD) shock prevention into a single, compact modular frame, this range offers multi-tiered protection against short circuits, overloads, and fatal earth leakage currents. Spanning all industry-standard sub-circuit amperages including 16A, 20A, 25A, 32A, and 40A, this high-spec safety switchgear range features an advanced 30mA trip threshold, specifically engineered to interrupt supply within milliseconds to prevent lethal electrical shocks to human life.

Manufactured to rigid German engineering benchmarks, this Siemens 10kA RCBO range is explicitly optimized for environments close to main step-down supply transformers or where high prospective fault currents occur. Featuring a robust 10,000A (10kA) short-circuit breaking capacity conforming to IEC/EN 61009-1, it delivers the ultimate electrical grid resilience required by modern safety codes. Equipped with premium internal component thermal blocks and universal C-Curve characteristics, this series is widely specified across Egypt for high-end medical clinics, operational theater labs, advanced IT servers, luxury villa kitchen pods, and wet-area utility rings where complete single-phase isolation is mandatory.

Comprehensive Range Capacity Configurations:

• Siemens 16A & 20A RCBOs: The standard consulting specification for premium socket outlets, operational laboratory machinery, and high-end smart home automation nodes.

• Siemens 25A & 32A RCBOs: Optimized protection for commercial kitchen equipment arrays, single-phase continuous server loops, and data communications racks.

• Siemens 40A RCBOs: High-capacity single-phase sub-feeders built to isolate localized sub-distribution panels, water pumps, and high-use commercial HVAC air management systems.

Key Technical Advantages:

• All-in-One Compact Lifesaver: Replaces individual MCB and RCCB configurations, saving vital spatial territory inside premium distribution panel boards.

• 10kA Industrial Breaking Capacity: Delivers heavy-duty short-circuit fault interruption certified for high-integrity infrastructure and code compliance.

• 30mA Earth Leakage Protection: Precision instantaneous disconnection upon tracking minute ground leaks, ensuring full human-life protection.

• Simultaneous 1P+N Disconnection: Concurrently opens Phase and Neutral lines to eradicate floating neutral hazards and dangerous return leakage loops.

• Patented Dual-Terminal Tunnel: Facilitates safe, concurrent connection of standardized pin-type copper busbars and flexible cable conductors up to 35 $mm^2$.
