Small three-phase motors on pumps, fans and conveyors need overload protection matched to a low full-load current. The Techspan TR2D09307 is a 3-pole bimetallic thermal overload relay with a 1.6 to 2.5 A setting range, trip class 10 and 1NO+1NC auxiliary contacts. It mounts directly under Techspan T-line TC1-D contactors to build a compact starter.
Why panel builders pick it
- Adjustable 1.6-2.5 A range covers small fractional and low-HP three-phase motors.
- Class 10 tripping with phase failure sensitivity for motor protection.
- 1NO+1NC auxiliary contacts to drop the contactor coil and signal a trip.
- Direct mounting under TC1-D09, D12 and D18 contactors.
- Temperature compensated from -20 to +60°C.

Pro tip from the counter
This relay's terminals line up only with Techspan T-line TC1-D09, D12 and D18 contactors. If you're replacing an overload on a starter built with another brand's contactor, check the pole spacing and mounting first, because a close-looking IEC relay from a different maker may not bolt under it.
Best for: small pump and fan motor starters, conveyor and packaging machine panels, OEM control panels, replacing tripped or failed overloads
