Product Description
5SU1646-6FP06
The Siemens 5SU1646-6FP06 is a 4-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO), offering comprehensive protection by combining earth leakage protection and overcurrent protection in one compact unit. With a B-characteristic tripping curve, it is designed for circuits with low inrush currents. The 300mA residual current sensitivity provides enhanced fire protection, making it suitable for specialized applications in residential, commercial, and industrial settings.
Key Features and Specification
- Rated Current (In): 6 A
- Rated Voltage (Un): 400 V AC
- Breaking Capacity: 6 kA
- Poles: 4
- Tripping Curve: B Characteristic (for resistive loads with low inrush current)
- Residual Current Type: Type A (detects AC and pulsating DC leakage currents)
- Rated Residual Current: 300 mA
- Energy Limiting Class: Not explicitly specified (refer to datasheet if required)
Technical Information
- Number: 5SU1646-6FP06
- EAN: 4001869578224
- Commodity Code: 85362010
- Catalog Reference: LV10
- Product Group: 5532
- Group Code: P310
- Lifecycle Status: PM300 – Active Product
Applications
- Suitable for use in 4-wire three-phase systems (e.g., TN-S or TT networks)
- Ideal for circuits with low inrush current, such as lighting, heating elements, or control circuits
- Provides protection against fire risks from earth faults with higher leakage threshold (300mA)
- Meets safety standards in installations requiring simultaneous overcurrent and earth leakage protection
Summary:
The Siemens 5SU1646-6FP06 RCBO is a specialized protection device designed for low-current, low-inrush circuits requiring enhanced fire protection. With 6A rated current, 300mA leakage sensitivity, and a B-curve tripping profile, it is well-suited for protecting sensitive equipment and ensuring compliance with electrical safety regulations in both residential and commercial environments.
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.
