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. ## End-of-life phase — sourcing reality Availability is confirmed through independent surplus and broker channels; quantities are lot-specific and quoted against an RFQ. ## Panel integration and compliance documentation As a DIN-rail-mount contactor in the A1A family, it integrates into standard control panels alongside motor starters and overload relays. The Thermal Magnetic trip block is factory-set and non-interchangeable in the field. ABB provides standard compliance documentation including RoHS and REACH declarations for the A1A series; UL and IEC certification data is available in the product drawing package.","metaTitle":"ABB A1A040TW-2 A1A 100 TMF 40-400 Contactor","metaDescription":"ABB A1A040TW-2 A1A 100 TMF 40-400 contactor, Thermal Magnetic type.
