A1A 100 TMF 40-400 — Thermal Magnetic protection profile
The ABB A1A040TW-2 is a Thermal Magnetic contactor from the A1A 100 TMF 40-400 series, carrying the full order code A1A040TW-2 A1A 100 TMF 40-400 2/ABB. The Thermal Magnetic designation means the unit combines a thermal overload element for sustained overcurrent protection with a magnetic trip element for short-circuit fault clearing — a dual-action protection scheme common in motor branch circuits.
