Technical Specifications Rated Insulation Voltage: 690 VAC Rated Operational Current: 32 A Contact Pole Number: multi‑pole synchronous contact groups Mounting Type: cabinet front‑panel mounting Front‑panel Protection Degree: IP65 Operating Mode: rotary manual handle Operating Temperature: ‑25 ℃ to +70 ℃
Functional Features Multi‑pole synchronous main circuit switching‑on and switching‑off. Disconnector function provides safe isolation gap for downstream circuit. Front‑panel rotary handle for local manual operation. High protection grade for cabinet front‑face installation. Mechanical position indication shows actual contact status.
Application Scenarios Manual main disconnector for control cabinet auxiliary power loop. Isolation switch for on‑site local operation box power supply. General‑purpose manual cut‑off switch for machine‑tool control panel. Maintenance isolation switch for industrial automation auxiliary circuit.
Performance Parameters Synchronous action for all pole contact groups. Adequate isolation gap satisfies safety disconnector requirement. Stable contact performance under rated long‑term load current.
Material Composition Flame‑retardant insulating switch housing. Metal rotary shaft and cam driving assembly. Silver alloy main contact sets. Front‑panel sealing rubber ring. Rear‑side screw terminal blocks.
Structural Features Front‑panel mounting fixing flange structure. Rotary operation handle with position mark. Multi‑pole stacked contact chambers inside housing. Rear‑facing terminals for incoming and outgoing circuit wiring.
Working Principle Rotary handle drives cam shaft rotation. Cam mechanism pushes all‑pole contact groups to close or open synchronously. Open position creates electrical isolation gap for downstream circuit.
Installation Requirements Mount switch through reserved cut‑out opening on cabinet front panel. Tighten mounting flange fixing parts. Complete incoming and outgoing circuit wiring at rear‑side terminals.
Usage Notes Do not operate under overload current condition. Confirm handle open‑position corresponds to real contact isolation status in commissioning. Protect front‑panel sealing rubber from mechanical damage.
