The ABB TA25DU14-20 is a thermal overload relay from the A-Line family, set for a 10-14 A motor full-load current range with a Class 20 trip characteristic. Class 20 means it allows up to 20 seconds of locked-rotor current before tripping — standard for general-purpose induction motors driving pumps, fans, and conveyors where the start-up transient is moderate.
This relay mounts directly to ABB A-Line contactors, snapping onto the contactor body without extra hardware. The DIN-rail footprint keeps the panel layout tight — one less SKU to bracket.
