Selection Guide
Use the following criteria to confirm the ABB IIRMR02 is the right choice — or to identify the correct replacement:
- Step 1 – Rated Current (In): Match the ampere rating to your circuit load calculation
- Step 2 – Residual Current Sensitivity (IΔn): Confirm 30 mA (personnel protection) or 300 mA (equipment protection)
- Step 3 – Poles: Verify 1P+N, 2P, 3P, or 4P configuration matches your panel design
- Step 4 – Breaking Capacity (Icn): Ensure rated short-circuit breaking capacity meets prospective fault current at installation point
- Step 5 – Trip Characteristic: Select Type B, C, or D curve based on load type (resistive, inductive, motor)
- Step 6 – Voltage Rating: Confirm 230 V / 400 V AC compatibility with your supply
- Step 7 – Certifications: Verify CE, CCC, or other regional marks required for your project

Replacement & Compatibility FAQ
Q: Can I replace the ABB IIRMR02 with an ABB DS201?
A: The DS201 is a functional RCBO equivalent. Verify the rated current, sensitivity, and pole configuration match your installation before substituting.
Q: Is the IIRMR02 compatible with third-party auxiliary contacts?
A: ABB recommends using IIRMR series accessories. Third-party accessories may fit physically but are not guaranteed to meet safety certification requirements.
Q: What is the difference between RCBO and RCCB?
A: An RCBO (Residual Current Circuit Breaker with Overcurrent protection) combines residual current protection with overcurrent/short-circuit protection in a single device. An RCCB provides only residual current protection and requires a separate MCB for overcurrent protection.
Q: How do I verify the authenticity of an ABB IIRMR02?
A: Check the ABB hologram label, verify the serial number via ABB’s official product verification portal, and request a certificate of conformity from your supplier.
Q: Does Konmask.com offer cross-reference support?
A: Yes. Contact our technical team with your existing part number and application requirements, and we will identify the best equivalent or replacement option.
