Product Description
5SU1346-6FP32
The Siemens 5SU1346-6FP32 is a 4-pole Residual Current Operated Circuit Breaker with Overcurrent Protection (RCBO), designed for comprehensive protection in modern 4-wire three-phase electrical installations. It combines residual current (earth leakage) and overcurrent (overload and short-circuit) protection in one compact unit. With a B-characteristic tripping curve, it is especially suited for circuits with low inrush currents.
Key Features and Specification
- Rated Current (In): 32 A
- Rated Voltage (Un): 400 V AC
- Breaking Capacity: 6 kA
- Poles: 4
- Tripping Curve: B Characteristic (ideal for circuits with low inrush currents)
- Residual Current Type: Type A (detects AC and pulsating DC residual currents)
- Rated Residual Current: 30 mA
- Energy Limiting Class: 1 (check for normative use limitations)

Applications
- Ideal for residential, commercial, and industrial 4-wire three-phase installations
- Suitable for protection of high-load circuits such as HVAC systems, large appliances, or industrial machines
- Designed for use in applications with low inrush currents
- Offers integrated protection against earth leakage, overloads, and short circuits
Summary:
The 5SU1346-6FP32 RCBO from Siemens delivers dependable protection for both people and electrical infrastructure. With its 32A rated current and 30 mA sensitivity, it is an excellent choice for environments requiring full protection in a 4-pole configuration. Its energy limiting Class 1 performance ensures enhanced system safety and reliability across a wide range of applications.
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.
