Thermal Magnetic overload — what the type means for the trip curve
The A1A015TW-1: The Thermal Magnetic designation means the overload protection uses a bimetal thermal element for low-level overcurrents and a magnetic coil for short-circuit trip. This sets the trip curve shape — the thermal side follows an inverse-time characteristic, the magnetic side snaps at a fixed multiple of the rating.
Lifecycle stage eol_hot — sourcing reality for this ABB contactor
For a BOM that requires this exact order code, the realistic path is to source new-old-stock or verified surplus through distribution.
Panel fit and contactor class
The Thermal Magnetic type integrates overload protection into the contactor body, saving panel space compared to a separate overload relay.
