KOA7 ThreePhase Electromagnetic Switch Key benefits Reliable threephase switching: Integrated threephase design delivers consistent connections under load and fast, dependable disconnection when needed, reducing downtime and improving operational safety. Clear, fast visual status: Distinct red and green mechanical switches make the switch state immediately visible for operators and first responders, lowering risk of error during emergencies or routine checks. Weather and dust resistance: IP54 rating protects the unit from dust ingress and water splashes, so it maintains stable performance in workshops, outdoor enclosures, and exposed equipment areas. Safetyfirst construction: Fireresistant PVC housing, a transparent protective cap, and a U release feature combine to reduce accidental operation and support safer manual access and maintenance. Function and compatibility Purpose: Electromagnetic switch designed for controlling and protecting threephase electrical circuits where reliable switching and quick disconnection are required. Compatibility: Suited for standard threephase systems and common industrial and commercial electrical panels. The integrated design reduces wiring complexity and saves panel space. Material and durability: Fireresistant PVC housing and robust internal construction deliver longterm service and added protection against heat and flame propagation. Performance: Designed to maintain contact integrity under normal operating conditions and to perform reliably in environments with dust or intermittent water exposure (IP54). Userfriendly features Colorcoded mechanical switches: Red and green switches provide unambiguous visual cues for stop/emergency and safe/operational states, enabling faster decisionmaking and safer response actions. Transparent protective cap: Allows visual inspection without exposing internal components, helping prevent accidental contact while checking status. U release feature: Provides a controlled manual release mechanism to help avoid unintended switch operation during maintenance or emergency procedures. Typical applications Industrial control panels and motor control centers where threephase motors and equipment require reliable switching and visible status indicators. Outdoor or semiexposed installations such as pump stations, HVAC units, and agricultural equipment where IP54 protection helps maintain performance in dusty or wet conditions. Construction, manufacturing, and maintenance environments where clear emergency indication and safe manual access are important for operator safety and regulatory compliance. What this delivers Safer, clearer operation with fast, reliable switching for threephase systems. Reduced wiring complexity and a compact integrated approach for easier installation. Durable, weatherresistant performance and safety features that support routine inspection and emergency response. Model: KOA7 electromagnetic switch — threephase integrated design with colorcoded mechanical switches, IP54 protection, fireresistant PVC body, transparent protective cap, and U release feature.
