ABB 1SDA067440R1 XT1S 160 TMD 63-630 4p F F 4-Pole 63A Fixed Molded Case Circuit Breaker

The ABB 1SDA067440R1 (XT1S 160 TMD 63-630 4p F F) is a 63 A, 4-pole, fixed-mounted molded case circuit breaker (MCCB) from the Tmax XT1 range, ABB's current-generation MCCB series (160 A frame). It is fitted with a thermal-magnetic (TMD) trip unit and is rated 50 kA Icu at 400 V AC. Weight is 1.4 kg.

Technical Specifications

Certifications & Standards

• RoHS: Compliant with the Restriction of Hazardous Substances Directive, ensuring reduced environmental impact
• REACH: Compliant with EU REACH regulation on chemical safety and substances of concern
• EU Directive 2011/65/EU & Amendment 2015/863: Fully compliant as of July 22, 2019, confirming restriction of hazardous substances in electrical and electronic equipment

Selection Notes

• Rated current is 63 A with a magnetic trip (Im) of 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 TMD trip unit is thermal-magnetic; check the thermal setting and magnetic trip values in the ABB catalog against the load and the protection coordination plan.
