ABB 1SDA066564R1 A3N 630 TMF 500-5000 3p F F 500A 3-Pole Fixed Molded Case Circuit Breaker

The ABB 1SDA066564R1 (A3N 630 TMF 500-5000 3p F F) is a 500 A, 3-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 4.85 kg.

Technical Specifications

Certifications & Standards

• IEC: Designed and tested in accordance with IEC standards for low-voltage circuit breakers, ensuring global interoperability and safety compliance.
• CE: Carries the CE mark, confirming conformity with applicable European Union directives for electrical equipment.
• RoHS: Compliant with EU Restriction of Hazardous Substances Directive, free from restricted heavy metals and halogenated flame retardants.
• REACH: Compliant with EU REACH regulation on chemical substances, supporting safe handling and disposal requirements.
• WEEE: Registered under the Waste Electrical and Electronic Equipment directive, supporting responsible end-of-life recycling.

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 3-pole version for three-phase circuits; select a 4-pole variant if the neutral must be switched. 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.
