ABB 1SDA067431R1 XT1S 160 TMD 50-500 3p F F 50A 3-Pole Fixed Molded Case Circuit Breaker

The ABB 1SDA067431R1 (XT1S 160 TMD 50-500 3p F F) is a 50 A, 3-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 1.167 kg.

Technical Specifications

Certifications & Standards

• RoHS: Compliant with the Restriction of Hazardous Substances Directive, ensuring restricted substances are within permitted limits
• REACH: Compliant with EU REACH regulation (EC No 1907/2006) for safe use of chemical substances
• EU Directive 2011/65/EU: Compliant with the European RoHS Directive restricting use of hazardous materials in electrical and electronic equipment
• Amendment 2015/863: Compliant with EU Delegated Directive 2015/863 amending Annex II of Directive 2011/65/EU, covering four additional restricted substances

Selection Notes

• Rated current is 50 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 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 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.
