Product Description
5SU1636-7FP20
The Siemens 5SU1636-7FP20 is a 3-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO), designed to ensure comprehensive protection by combining residual current (earth leakage) and overcurrent (overload and short circuit) safeguards in one unit. With a C-characteristic tripping curve and 300mA residual current sensitivity, this RCBO is optimized for use in industrial and commercial installations with moderate inrush current loads.
Key Features and Specification
- Rated Current (In): 20 A
- Rated Voltage (Un): 400 V AC
- Breaking Capacity: 6 kA
- Poles: 3
- Tripping Curve: C Characteristic (ideal for circuits with moderate inrush, such as motors and mixed loads)
- Residual Current Type: Type A (detects AC and pulsating DC leakage currents)
- Rated Residual Current: 300 mA
- Energy Limiting Class: 1 (check for normative use limitations)
Technical Information
- Number: 5SU1636-7FP20
- EAN: 4001869578057
- Commodity Code: 85362010
- Catalog Reference: LV10
- Product Group: 5516
- Group Code: P310
- Lifecycle Status: PM300 – Active Product
Applications
- Designed for commercial and industrial installations requiring enhanced fire protection
- Suitable for three-phase distribution circuits with moderate inrush currents
- Prevents electrical fires by limiting earth leakage currents to 300mA
- Offers space-saving integration of earth leakage and overcurrent protection
Summary:
The Siemens 5SU1636-7FP20 RCBO is a robust and compact device tailored for applications that demand reliable dual protection. Featuring a 20A current rating and 300mA leakage sensitivity, it is particularly well-suited for installations where higher leakage current thresholds are acceptable. The C-curve tripping behavior makes it ideal for circuits containing inductive components, while energy limiting class 1 performance supports high safety standards in accordance with regulatory norms.
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.
