SZD1132/400010 32A 4Pole 2Position Rotary Cam OnOff Load Circuit Breaker Transfer Switch A compact, reliable transfer switch designed for safe and clear manual switching of load circuits. The SZD1132/400010 provides a 2position rotary cam mechanism for positive on and off switching across four poles, suitable for industrial and commercial electrical panels. Key benefits Positive isolation and clear switching status through a rotary cam 2position design, reducing switching errors during maintenance and operation. Robust electrical performance for 32A circuits, with shortcircuit making capacity and shorttime withstand current to handle switching in demanding conditions. Simple integration into control panels and distribution boards thanks to a common form factor and plastic housing that reduces weight. Principal specifications Model: SZD1132/400010 Color: 32A 400010 Current rating: 32A Poles: 4pole Positions: 2position (OnOff) Mechanism: Rotary cam onoff power combination switch Material: Plastic housing Rated insulation voltage Ui: 660V Rated working voltage Ue: AC220V/380V Rated working current Ie: 32A Conventional heating current Ith: 32A Use category: AC21A Rated shortcircuit making capacity Icm: 1070A Rated shorttime withstand current Icw: 756A for 1 second What makes this switch stand out Fourpole switching provides simultaneous control of multiphase or multiline circuits for coordinated isolation. shortcircuit making capacity and specified shorttime withstand current improve resilience during load transfers. Straightforward manual operation with a rotary cam reduces complexity compared to multicomponent transfer arrangements. Typical applications Manual transfer between mains and backup power sources for small generators and standby supplies in workshops or small commercial sites. Load isolation and manual control in industrial control panels, motor circuits, and motor starter assemblies. Distribution board switching for singlephase and threephase circuits in light industrial and commercial installations. Installation and compatibility notes Designed for panel mounting in distribution and control equipment compatible with AC220V or AC380V systems. Confirm panel wiring and shortcircuit protection coordination to match the switch ratings and the overall system protection scheme. Use within the specified current and voltage ratings and observe the AC21A use category for appropriate switching duties. This transfer switch provides clear, reliable manual switching for 32A load circuits where fourpole isolation and robust shortcircuit performance are required.
