It's designed to bolt directly onto A-Line series contactors in the A/AE/AL9 through A/AE/AL40 frame sizes — that's the common small-to-mid motor starter range for panel builders. ## Trip Class 20 and what that means on site Trip Class 20 means the relay will let the motor draw locked-rotor current for up to 20 seconds before tripping. That's the standard for general-purpose induction motors starting under load — conveyors, pumps, compressors. It's not the fast-acting Class 10 you'd spec for a submersible or a high-inertia fan that needs a longer ramp; Class 20 is the middle ground that covers most line-started three-phase motors. ## Adjustment and reset — field-friendly The 13–19 A range covers a 6 A span, which gives you some headroom to dial in the actual motor FLA on site without swapping the heater pack. The reset is selectable between manual and automatic — flip it to auto for remote restart on an unattended line, stick with manual for a guarded machine where you want someone to walk over and look before hitting reset.","metaTitle":"TA25DU19-20 Overload Relay, 13-19 A, Trip Class 20","metaDescription":"TA25DU19-20 IEC thermal overload relay, 13-19 A adjustable range, Trip Class 20.
