The PASS SEYMOUR 7803MD is a manual controller switch rated for 30 amps and 600 volts across a 3-phase, 3-pole configuration. It provides direct manual control of three-phase electrical loads without relying on magnetic starters or automated switching components. Electricians use this switch in industrial and commercial panel builds where a simple, reliable hand-operated disconnect or motor control point is required. At 3.35 pounds, it is a solid, field-ready unit suited for permanent installation in control enclosures or distribution assemblies.
This manual controller switch is used in commercial and light industrial electrical applications where three-phase power distribution requires a dedicated manual switching point. Typical install scenarios include motor branch circuits, HVAC equipment disconnects, and machinery control panels. It is appropriate for new construction wiring as well as replacement work in existing three-phase systems where a manual switching device is called for at the equipment level.
Designed as an OEM-style replacement or new-install manual controller switch for commercial and industrial three-phase electrical systems rated up to 600 volts and 30 amps.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before mounting or wiring the switch. Verify that supply voltage and load current do not exceed the 600-volt, 30-amp ratings before energizing. Proper enclosure selection and conductor sizing per NEC Article 430 apply when used in motor control applications.
