The TMD trip unit gives you a fixed thermal curve for overload protection and a fixed magnetic pickup for short-circuit protection — no adjustment dials, so what you spec is what you get. The XT2S frame is the standard compact MCCB for panel builders who need a UL489 / IEC 60947-2 device in a 160 A frame size. ## Where it lands in a panel Three-pole front-terminal version means the line and load lugs are accessible from the front, which simplifies busbar connections in a distribution board. The 160 A frame gives you headroom for the adjustable trip range — the breaker itself is physically sized for the frame, not the trip setting, so the enclosure cutout stays the same whether you set it at 6.3 A or 63 A. ## What the TMD trip means for coordination The TMD trip is a fixed thermal-magnetic design — the thermal element handles sustained overloads (time-inverse curve), and the magnetic element clears short-circuits instantaneously above a fixed threshold. No interchangeable trip units or electronic adjustments. For selectivity studies, you rely on the fixed curve published in ABB's coordination tables. The 6.3-63 A range covers a wide band of downstream loads; if you need a tighter adjustment window or electronic ground-fault protection, you would step up to the TMA or Ekip trip families in the same XT2S frame.","metaTitle":"ABB XT2SE3063BFF000XXX XT2S 160 TMD 6.3-63 3P F F, current l","metaDescription":"ABB XT2SE3063BFF000XXX XT2S 160 molded case circuit breaker, TMD 6.3-63 A, 3-pole.
