Applications & Use Cases

The TF42-0.13 is engineered for protecting small three-phase motors and loads in industrial automation systems, control panels, and motor control centers (MCCs). Its ultra-low current range of 0.10–0.13 A makes it particularly suitable for fractional horsepower motors, fan drives, pump controllers, and conveyor systems where precise overcurrent protection is critical. As part of ABB's TF42 Series, the TF42-0.13 is designed to pair directly with compatible ABB contactors, streamlining panel assembly and reducing wiring complexity in demanding electrical installations.
