Product Description
5SU1326-6FP25
The Siemens 5SU1326-6FP25 is a compact and reliable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed for protection against overcurrents (overload and short-circuit) and earth leakage currents. It combines two essential safety functions in a single device, making it ideal for residential, commercial, and light industrial installations.

Key Features and Specification
- Rated Current (In): 25 A
- Rated Voltage (Un): 230 V AC
- Breaking Capacity: 6 kA
- Poles: 2 (1P + N)
- Tripping Characteristic: B Curve (for resistive and low-inductive loads)
- Residual Current Type: Type A (detects AC and pulsating DC faults)
- Residual Current Sensitivity: 30 mA (provides personal protection)

Applications
- Ideal for final circuit protection in buildings
- Suitable for use in homes, offices, and light commercial settings
- Protects against electric shock and fire hazards caused by earth faults or wiring failures
- Especially useful where both overcurrent and residual current protection is needed in limited space
Summary:
The Siemens 5SU1326-6FP25 RCBO offers dependable and efficient protection with a 25 A rating and a 30 mA leakage sensitivity. Designed for ease of installation and reliable performance, it helps enhance the overall electrical safety of modern distribution systems.
Frequently Asked Questions
What is MCB protection?
✅ MCB (Miniature Circuit Breaker) protects against overloads and short circuits. Overload protection works via a bimetallic strip (thermal operation), while short-circuit protection uses a tripping coil (electromagnetic operation). This ensures electrical safety in homes, businesses, and industries.
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.
