Product Description
5SU1636-6FP20
The Siemens 5SU1636-6FP20 is a 3-pole Residual Current Operated Circuit Breaker with Overcurrent Protection (RCBO) designed to provide dual protection—against residual current (earth leakage) and overcurrent (overload and short circuit)—in a single compact device. Featuring a B-characteristic tripping curve, this model is well-suited for circuits with low inrush currents such as lighting, resistive loads, or general-purpose outlets. With a rated current of 20A and residual current sensitivity of 300 mA, it also supports fire protection and specialized industrial safety applications.
Key Features and Specification
- Rated Current (In): 20 A
- Rated Voltage (Un): 400 V AC
- Breaking Capacity: 6 kA
- Poles: 3
- Tripping Curve: B Characteristic (optimized for resistive or low inrush current loads)
- Residual Current Type: Type A (sensitive to AC and pulsating DC leakage currents)
- Rated Residual Current: 300 mA
- Energy Limiting Class: 1 (check for normative use limitations)
Technical Information
- Number: 5SU1636-6FP20
- EAN: 4001869577999
- Commodity Code: 85362010
- Catalog Reference: LV10

Applications
- Ideal for use in residential, commercial, and light industrial three-phase systems
- Suitable for fire prevention measures where 300 mA sensitivity is required
- Designed for circuits with resistive or low inrush loads (e.g., lighting, heating)
- Protects equipment and personnel by detecting leakage current, overloads, and short circuits
Summary:
The 5SU1636-6FP20 RCBO by Siemens delivers dependable and space-efficient protection for three-phase electrical installations. Its 20A rated current, combined with 300 mA leakage sensitivity and B-curve tripping, makes it suitable for protecting both equipment and wiring in applications requiring moderate capacity. As part of energy limiting class 1, it offers a fast response to fault conditions, although users should verify normative usage limitations to ensure compliance with local electrical regulations.
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.
