Material Composition
Contact: silver-nickel alloy. Coil: copper winding with insulation. Housing: phenolic resin with metal mounting bracket. Terminals: tin-plated copper.
Structural Characteristics
It features open-frame construction, mounting bracket, screw terminals, coil terminals, and dust cover option.
Working Principle
When coil voltage is applied, the magnetic armature pulls in, closing the normally open contact and opening the normally closed contact. When voltage is removed, the return spring resets the contacts to normal position.
Installation Requirements
Mount on panel or DIN rail with hardware. Wire power and load circuits per contact rating. Observe correct coil polarity. Connect protective circuit for inductive loads.
Usage Notes
Do not exceed contact current and voltage ratings. Install surge suppression for inductive loads. Inspect contacts periodically for wear. Follow lockout procedures when servicing.
