Product Description
5SU1653-1KK32
The Siemens 5SU1653-1KK32 is a 1P+N Residual Current Operated Circuit Breaker with Overcurrent Protection (RCBO) designed for high-performance protection in single-phase electrical systems. This compact device offers dual functionality—earth leakage protection and overcurrent protection—in one unit. With a C-curve tripping characteristic and Type AC residual current sensitivity, it is optimized for circuits with moderate inrush currents and general AC loads.
Key Features and Specification
- Rated Current (In): 32 A
- Rated Voltage (Un): 230 V AC
- Breaking Capacity: 4.5 kA
- Poles: 1P+N (Single-phase with neutral)
- Tripping Curve: C Characteristic (for circuits with moderate inrush currents)
- Residual Current Type: Type AC (detects sinusoidal AC leakage currents)
- Rated Residual Current: 300 mA
- Energy Limiting Class: Not specified
Technical Information
- Number: 5SU1653-1KK32

Applications
- Suitable for residential, commercial, and light industrial installations
- Ideal for protecting 32A-rated circuits feeding high-power appliances, HVAC units, or industrial sockets
- Prevents hazards caused by leakage currents, overloads, and short circuits
- Supports compliance with electrical safety regulations and improves operational reliability
Summary:
The 5SU1653-1KK32 RCBO by Siemens offers robust and efficient protection for 32A single-phase AC circuits, with a 300mA residual current threshold. Its C-curve tripping is suitable for installations where moderate inrush currents occur, such as in inductive loads. Compact and reliable, it’s a preferred choice for applications demanding safety, efficiency, and code compliance in modern electrical systems.
Frequently Asked Questions
What is the rule for installing an SPD?
✅ SPD (Surge Protection Device) connections should be as short as possible to minimize the voltage protection level (Up). The total length of connections to the network and earth should not exceed 50 cm to ensure effective surge protection.
How to Set Up a Surge Protector?
1.Turn off power at the circuit breaker.
2. Remove the old outlet.
3. Connect wires to the new surge-protected outlet per the manufacturer’s instructions.
4. Secure the outlet in the box and replace the cover plate.
5. Restore power and test the outlet.
What is the use of RCCB in Siemens?
✅ Siemens Residual Current Circuit Breakers (RCCBs) protect against electric shock by detecting leakage currents. If the leakage exceeds a set limit, the RCCB immediately disconnects the circuit, ensuring safety from direct or indirect contact with live components.
Where is an RCBO used?
✅ RCBOs (Residual Current Circuit Breakers with Overcurrent protection) are commonly used in various residential, commercial, and industrial applications. Typical use cases include power distribution boards, emergency lighting circuits, HVAC (Heating, Ventilation, and Air Conditioning) systems, socket outlets, and swimming pool equipment. RCBOs are ideal for protecting individual circuits where both earth fault and overcurrent protection are required.
Where to Install RCCB?
✅ RCCBs should be installed in the distribution board (DB box) or circuit breaker panel to protect against current leakages caused by faulty wiring, ageing insulation, or defective appliances.
