Technical Specifications Rated Insulation Voltage: 690 VAC Rated Operational Current: 32 A Pole Configuration: multi‑pole synchronous contact groups Mounting: cabinet front‑panel cut‑out mounting Front‑panel Protection Class: IP65 Operation: rotary manual handle Operating Temperature: ‑25 ℃ to +70 ℃
Functional Features Multi‑pole synchronous make‑and‑break for power or control circuit. Disconnector isolation function for safe maintenance work. Mechanical position marking indicates actual contact status. Front‑panel rotary handle for local on‑site operation. High‑protection front‑panel structure adapts industrial workshop environment.
Application Scenarios Maintenance isolation switch for industrial cabinet auxiliary power circuit. Manual cut‑off switch for pump and fan local operation box. Disconnecting switch for machine‑tool control panel power supply. Isolation device for small‑scale on‑site distribution auxiliary loop.
Performance Parameters All‑pole contacts complete switching action synchronously. Isolation gap meets low‑voltage disconnector safety standard. Contact conductivity remains stable under continuous rated load.
Material Composition Flame‑retardant insulating main housing. Metal rotary shaft and cam driving mechanical assembly. Silver alloy multi‑pole contact components. Front‑panel sealing rubber ring. Rear‑side screw wiring terminal blocks.
Structural Features Front‑panel mounting flange for cabinet installation. Rotary operating handle with position symbol mark. Stack‑type multi‑pole contact chambers inside housing. Rear‑side terminals for upstream incoming and downstream outgoing wiring.
Working Principle Manual rotation of front‑panel handle drives internal cam shaft. Cam mechanism pushes multi‑pole contact groups to close or open synchronously. Open‑position creates safe electrical isolation gap between upstream and downstream circuit.
Installation Requirements Install switch body through cabinet front‑panel reserved opening. Secure mounting flange firmly to cabinet panel. Carry out upstream and downstream circuit wiring at rear‑side terminals.
Usage Notes Switch shall not be used for breaking short‑circuit fault current. Check handle position indication matches actual contact status in commissioning. Avoid mechanical damage to front‑panel sealing rubber ring.
