1SDA068092R1 ABB XT4N 250 MCCB 3P TMD 250-2500A 36kA Tmax XT

The ABB XT4N 250 TMA 250-2500 3p F F (article 1SDA068092R1) is a fixed three-pole circuit breaker from the TMAX XT4N 250 series, equipped with a thermomagnetic TMA release rated at 250 A. It provides both thermal overload and magnetic short-circuit protection, with a magnetic trip current range of 1250 to 2500 A. The fixed mounting and front terminal design make it suitable for permanent panel installations requiring direct wiring access.

Technical specifications:

• Series: XT4N 250 TMA 250-2500 3p F F
• ABB article number: 1SDA068092R1
• EAN: 8015644695835
• Number of poles: 3
• Rated current (In): 250 A
• Release type: Thermomagnetic (TMA)
• Magnetic trip current (I3): 1250 to 2500 A
• Mounting: Fixed (F)
• Terminal type: Front terminals (F)

Features and benefits:

• Three-pole design protects all phases simultaneously within a single device
• Thermomagnetic TMA release integrates thermal overload and magnetic short-circuit tripping in one unit, eliminating the need for separate protective devices
• Adjustable magnetic trip range from 1250 to 2500 A supports selective coordination with upstream and downstream protection
• Fixed chassis construction gives a secure, permanent installation without a withdrawable cradle
• Front terminal entry simplifies cable routing and reduces wiring time in compact panel enclosures

Applications:

• Feeder and sub-distribution protection in industrial switchboards and motor control centres
• Overcurrent and short-circuit protection for large motor feeders up to 250 A
• Incoming circuit protection for industrial machinery, processing lines, and heavy equipment
• Distribution panels where a fixed, front-terminal three-pole breaker is specified by the designer
