General Electric QMR36I Fusible Interrupter Switch

The General Electric QMR36I operates as a precision-engineered 3-pole fusible interrupter switch specifically designed to manage demanding electrical loads reaching 30A within industrial-grade circuits that remain consistently rated for safe operation at 600VAC. This robust electrical component integrates standard fuse provisions directly into its internal switching mechanism to enable simultaneous safe circuit de-energization and precise overcurrent protection for sensitive downstream equipment contained within a standard commercial panel assembly. Service technicians frequently utilize this heavy-duty power switch for permanently isolating individual branch power sources across broad commercial or manufacturing facilities to fully comply with mandatory lockout/tagout procedures during scheduled maintenance on powered branch circuits serving various industrial machinery. By engineering a clearly visible air break contact, the unit confirms a verified zero-energy state to ensure that qualified repair personnel can safely commence mechanical work on connected machinery without the inherent risk of accidental re-energization during troubleshooting repairs.
