ABB 1SDA066575R1 A3S 630 ELT-LI In=630 4p F F 630A 4-Pole Fixed Molded Case Circuit Breaker

The ABB 1SDA066575R1 (A3S 630 ELT-LI In=630 4p F F) is a 630 A, 4-pole, fixed-mounted molded case circuit breaker (MCCB) from the Formula A3S range, ABB's compact and economical MCCB series for low-voltage distribution protection. It is fitted with an ELT-LI electronic trip unit (long-time and instantaneous protection) and is rated 50 kA Icu at 400 V AC. Dimensions (W × H × D) are 186 mm × 205 mm × 103.5 mm and weight is 6.4 kg.

Technical Specifications

Certifications & Standards

• CE: Compliant with European Union low-voltage and electromagnetic compatibility directives
• IEC: Designed and tested in accordance with IEC standards for low-voltage switchgear and controlgear
• RoHS: Restriction of Hazardous Substances compliant, free from regulated hazardous materials
• REACH: Compliant with EU REACH regulation on chemical substances in electrical equipment
• WEEE: Registered under the Waste Electrical and Electronic Equipment directive for responsible end-of-life disposal

Selection Notes

• Rated current is 630 A; check it against the continuous load current of the circuit being protected.
• Icu is 50 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; 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 ELT-LI trip unit is electronic and, per its designation, covers long-time and instantaneous protection; check that this matches the coordination study.
