ABB 1SDA066572R1 A3N 630 TMF 500-5000 4p F F InN=100%In 500A 4-Pole Fixed Molded Case Circuit Breaker

The ABB 1SDA066572R1 (A3N 630 TMF 500-5000 4p F F InN=100%In) is a 500 A, 4-pole, fixed-mounted molded case circuit breaker (MCCB) from the Formula A3N range, ABB's compact and economical MCCB series for low-voltage distribution protection. It is fitted with a fixed thermal-magnetic (TMF) trip unit and is rated 36 kA Icu at 400 V AC. Weight is 6.5 kg.

Technical Specifications

Certifications & Standards

• CE: Compliant with European Union directives for low-voltage electrical equipment
• IEC: Designed and tested in accordance with IEC standards for circuit breakers
• RoHS: Restriction of Hazardous Substances compliant, free from restricted materials
• REACH: Compliant with EU REACH regulations on chemical substances
• WEEE: Compliant with EU Waste Electrical and Electronic Equipment directive for responsible disposal

Selection Notes

• Rated current is 500 A with a magnetic trip (Im) of 5000 A; check it against the continuous load current of the circuit being protected.
• Icu is 36 kA at 400 V AC; confirm it is equal to or higher than the prospective fault current at the installation point.
• This is a 4-pole version with the neutral pole rated InN = 100% In; use it where the neutral conductor must be switched, and confirm the pole count matches the system. Mounting is fixed (not plug-in or withdrawable).
• The TMF trip unit has fixed thermal and magnetic thresholds, so choose the rating that matches the load rather than relying on field adjustment.
