The SZD1140/300010 is a 2position ON OFF panel mounted isolator with load break capability for threephase electrical circuits. It is rated for 660V and 40A in a 3P configuration, providing a reliable means to isolate and disconnect load circuits in industrial power systems. Key benefits Safe circuit isolation: enables reliable disconnection of threephase circuits to allow maintenance or servicing without energizing the load. Simple operation: twoposition ON OFF action provides clear, quick control over the circuit status. Compact panel integration: panelmounted design fits standard electrical control panels, helping to keep equipment layouts clean and organized. Load break capability: designed to interrupt current as part of an isolator/Load Break Switch function, enabling practical isolation in normal operating conditions. Clear status indication: straightforward ON and OFF positioning aids in quick verification of circuit state. Key attributes Model: SZD1140/300010 Type: 2 Position ON OFF panel mounted isolator with load break switch Poles: 3P (threephase) Voltage rating: 660V Current rating: 40 Amp Functionality: current cut off isolator with load breaking capability Mounting: panelmounted design suitable for installation in electrical control panels Compliance: aligned with standard 3P 660V threephase isolation requirements for panel installations Technical specifications Circuit configuration: threephase (3P) Operating positions: ON and OFF Maximum system voltage: 660V Continuous current rating: 40 A Mounting method: panel mount Function type: isolator with load break switch Applications and use cases Maintenance isolation in industrial control panels: use the SZD1140/300010 to safely disconnect a threephase circuit before servicing motors, drives, or feeders. Control panel energy isolation: provide a dedicated, clearly identifiable disconnect point in distribution or motor control panels to enable safe deenergization during routine checks. Factory and plant wiring: integrate in electrical rooms or equipment enclosures where a reliable ON/OFF disconnection is required for 3P circuits at 660V and up to 40A. Installation considerations Suitable for panelmounted installation in threephase electrical systems. Ensure compatibility with the surrounding panel design and meet local electrical codes and guidelines for disconnect devices. Verify that the circuit to be isolated does not exceed the 40A rating and that 660V is within the system operating parameters.
