Why Choose the ABB MT-350B Potentiometer?
The ABB MT-350B is a complete 50 kΩ control potentiometer designed for adjustable analogue control and set-point functions in industrial machinery, control panels and automation systems. Part of the ABB modular pilot device range, it combines a black rotary knob with a durable chrome-metal bezel and is designed for standard 22 mm control-panel mounting.
The MT-350B provides maintained rotary adjustment across a 280° mechanical operating angle, allowing operators to make smooth manual adjustments to compatible control circuits. Its integrated 50 kΩ resistor makes it suitable for applications such as speed reference, timing adjustment, process set-point selection and other variable control functions.
Engineered for industrial control environments, the MT-350B has a 2 W power rating, 900 V insulation voltage and IP66 front-side protection. Screw connections support secure control wiring, while the modular 22 mm format simplifies integration into operator stations and electrical control panels.
