-
Continuous-duty design: Optimized for drive functions with slow, stable switching under sustained loads
Usage Notes
-
Polarity Matters: Magnetic blowouts make contactors polarity-sensitive; follow ‘+’ markings
-
Interrupted Load Switching: Can increase resistance due to frequent arcing
-
Uninterrupted Load: Maintains low resistance and prolongs contact integrity
Ideal Applications
-
Electric drive systems
-
Forklifts and material handling equipment
-
Winches and traction systems
