Quantities are confirmed at RFQ; there is no factory lead time to rely on. ## Trip unit and rating — what the TMF 50-500 tells you The TMF trip unit is a thermal-magnetic fixed type: the thermal element provides overload protection with a 50 A continuous current rating (In=50 A), and the magnetic element provides short-circuit protection adjustable between 50 A and 500 A (10× In). This is a 2-pole breaker, so it switches and protects both poles in a single-phase or DC circuit. The 2-pole form factor suits single-phase branch circuits or DC loads where both lines need overcurrent protection. Verify the terminal wire range and torque spec from the ABB A1A installation sheet before terminating.","metaTitle":"ABB A1A050TW-2 MCCB, 50 A, TMF Trip, 2-Pole, EOL Hot","metaDescription":"ABB A1A050TW-2 molded case circuit breaker, 50 A TMF trip unit, 2-pole, UL listed.

It is a different frame size (XT4 vs A1A) and has three poles instead of two, so it will not drop into the same panel footprint without rewiring and a larger DIN space."},{"question":"What compliance documentation is available for A1A050TW-2?","answer":"The listing confirms UL listing.
