ABB 1SDA062658R1 T7H 800 PR231/P LS/I In=800A 3p F F M 800A 3-Pole Fixed Molded Case Circuit Breaker

The ABB 1SDA062658R1 (T7H 800 PR231/P LS/I In=800A 3p F F M) is a 800 A, 3-pole, fixed-mounted molded case circuit breaker (MCCB) from the Tmax T7 range of ABB molded case circuit breaker frames. It is fitted with a PR231/P LS/I electronic trip unit and is rated 70 kA Icu at 400 V AC. Dimensions (W × H × D) are 210 × 268 × 178 mm and weight is 11 kg.

Technical Specifications

Certifications & Standards

• CE: Conforms to European Union safety, health, and environmental protection requirements
• IEC: Designed and tested in accordance with IEC low-voltage switchgear and controlgear standards
• RoHS: Compliant with the Restriction of Hazardous Substances Directive, limiting use of restricted materials
• REACH: Meets EU REACH regulation requirements for chemical substance safety
• WEEE: Compliant with the Waste Electrical and Electronic Equipment Directive for responsible end-of-life disposal

Selection Notes

• Rated current is 800 A; check it against the continuous load current of the circuit being protected.
• Icu is 70 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 PR231/P LS/I is an electronic trip unit with long-time (L), short-time (S) and instantaneous (I) protection, so thresholds can be coordinated with upstream and downstream devices.
