ABB 1SDA066547R1 A2N 250 TMF 250-2500 2p F F 250A 2-Pole Fixed Molded Case Circuit Breaker

The ABB 1SDA066547R1 (A2N 250 TMF 250-2500 2p F F) is a 250 A, 2-pole, fixed-mounted molded case circuit breaker (MCCB) from the Formula A2N 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. Dimensions (W × H × D) are 70 mm × 150 mm × 60 mm and weight is 0.9 kg.

Selection Notes

• Rated current is 250 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 2-pole version; confirm the pole count matches the circuit it will protect. 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.
