Coil
Housed within the magnet frame, the solenoid (coil) is energised to generate the electro magnetic force for moving the armature and thus operating the main contacts.
Our coil winding wire is Class H, rated for 180 Degree Celsius insulation.
Coil Connection
Coil connection is typically via 6.3mm faston spade terminals. Coil terminals are not polarity sensitive unless suppression is fitted, and the coil is marked accordingly. Flying leads, M5 studs, 4.8mm faston, JPT and other connection methods are available dependant on contactor type.
Coil Finish
Vacuum impregnated coils are available to safeguard against shock and vibration and / or high humidity.
