ABB XT3N 1SDA068058R1 250 MCCB 200A 3P 415VAC 36kA

The ABB XT3N 250 TMD 200-2000 3p F F (article 1SDA068058R1) is a three-pole fixed-mount molded case circuit breaker from ABB's TMAX XT3N 250 series. It is fitted with a thermomagnetic release (TMD) covering an adjustable current range of 200 to 2000 A, making it suited to demanding low-voltage distribution and protection duties. Connection is made via front terminals, and the fixed-mounting design locks the unit permanently into the switchgear assembly.

Technical specifications:

• Series: XT3N 250 TMD 200-2000 3p F F
• ABB article number: 1SDA068058R1
• EAN: 8015644019297
• Product type: Molded case circuit breaker (MCCB)
• Poles: 3 (three-pole)
• Release type: Thermomagnetic (TMD), adjustable
• Current range: 200-2000 A
• Mounting: Fixed
• Terminal type: Front terminals

Features and benefits:

• Thermomagnetic TMD release delivers both overload (thermal) and short-circuit (magnetic) protection within a single unit, removing the need for separate devices.
• Adjustable current range of 200 to 2000 A allows the trip setting to be matched to the specific circuit requirements.
• Fixed mounting provides a secure, permanent installation that does not allow the breaker to be withdrawn under load, supporting safe panel operation.
• Front terminal connection gives direct, accessible wiring points, simplifying installation and maintenance in panel enclosures.
• Three-pole design covers all three live conductors simultaneously for coordinated disconnection of three-phase circuits.

Applications:

• Protection of outgoing feeders in three-phase main and sub-distribution boards.
• Overload and short-circuit protection in industrial power distribution panels.
• Incomer or feeder protection in low-voltage switchgear assemblies.
• Fixed-installation circuit protection where a withdrawable breaker is not required.
