Molded-case branch protection. Adjustable overloads set to nameplate current. Isolated control power. Phase monitoring. Listed and marked under UL 508A, file E547664.
208 / 230 / 460 V · 60 HZ · 1–30 HP · SIMPLEX TO MULTI-MOTOR · NEMA 4X
You open the door on a 9000 Series power section and the first thing you notice is the order. Two complete motor circuits sitting exactly the way the current is going to run. Nothing random. Nothing copied.
Current hits the branch first. One dedicated three-pole frame per motor. Rail-mounted so you can pull a single unit without touching its neighbors. Selected hard against the motor’s locked-rotor characteristics. A fault shows up and all three legs drop out together. Reset it and go — you don’t replace them.
Follow the path down and there sit the contactors, the overload strapped tight to each frame. Rated for the real duty the motor is actually going to see. Full voltage, across-the-line. Dial and trip flag both out in the open. Set it once to the nameplate and leave it alone.
Control power gets its own path. A listed transformer takes two legs through its own two-pole molded-case protection and steps them down to a clean, isolated 120 — bonded at the panel, independent of the motor branches, with Class CC time-delay fuses adding another layer before anything critical gets powered. The site brings three phase conductors and ground; no neutral required. And the alarm branch is fused separately again, so annunciation survives a fault in the controls.
The operator station stays clean and field-ready. HOA for each pump. Run lights. Optional overload indicators, phase protection, seal and leak alarms — stacked exactly the way the job demands.
Short conductor runs. Everything labeled to the print. Every landing front-accessible. The layout itself is almost a service manual.
This is the 9000 Series. 208, 230 and 460 volt, 60 hertz, 1 to 30 horsepower, simplex to multi-motor, NEMA 4X. Built for wye, delta or high-leg services when the site requires it. UL 508A Listed, file E547664.
DRESSED TO IMPRESS. BUILT FOR THE STRESS.
BRANCH BREAKERS · CONTACTORS · ADJUSTABLE OVERLOADS
Overload protection is in the panel, adjustable, and set to the nameplate full-load current of the connected motor. Fixed heater elements chosen from a chart have no place in this series.
One relay per motor, trip class matched to the starting duty. The trip contact is wired in series with its own contactor coil: a trip stops that motor in every selector position, including HAND, and stops nothing else.
Where the supply or the duty warrants it, a phase monitor relay supervises phase loss, phase reversal, voltage imbalance and under- and over-voltage, and opens the starter circuit before damage accumulates in the windings.
Simplex, duplex, triplex and multi-motor
Lead/lag alternation, per cycle or on demand
Both-on override for high inflow, independent of the alarm
Seal-in float logic — full drawdown, no cycling at the on level
HAND / OFF / AUTO per motor, with run indication
PLC sequencing where the process exceeds relay logic
208, 230 and 460 V three-phase, 60 Hz · 1–30 HP per motor
Generator inlet receptacle with manual transfer — standby power lands on a listed inlet, under interlock
Phase monitoring · elapsed-time indication · remote alarm contacts
NEMA 4X enclosures for wet, corrosive and outdoor service
Alarm circuits fused independently of the controls
Dry contacts for telemetry, SCADA or cellular notification
Provide the motor nameplate data, the service voltage and available fault current, the required control sequence, and the installation environment. A submittal drawing precedes fabrication. The as-built drawing ships with the panel, and the two match.
ONE CONDUCTOR PER TERMINAL · NUMBERED TO THE DRAWING
Every field device lands on its own numbered terminal. One conductor per termination — no doubled leads, no shared screws. Every terminal is torqued to the value published for its block family; a panel containing more than one family is torqued to more than one value.
Every control conductor carries a wire number, the number appears on the ladder, and the ladder ships with a landing schedule for both ends of every wire. The inside of the door carries that panel's terminal diagram, the hazards specific to it — including which circuit remains energized with the control fuse removed — and the fuse types and ratings by position.
This is the difference between a panel that works at commissioning and a panel that is still serviceable in its second decade.
Legacy Controls is a UL 508A Listed industrial control panel shop, file E547664. The Listing is what authorizes the mark on the panel; the obligations behind it govern how every panel is built.
Each panel ships with a nameplate stating its own ratings: supply voltage, frequency and phase, total full-load amperes, largest motor, short-circuit current rating, enclosure type, and the wiring diagram it was built to. The plate states it so that no one has to ask.
SCCR is the fault current the assembly is rated to withstand, established for the panel as a whole — not inherited from the highest-rated device inside it. It is marked because the installer must compare it against the available fault current at the point of installation. Feeder protection and the main disconnect are field supplied and sized to the NEC.
Duplex · 230 V three-phase · two 3 HP pumps. Individual three-pole branch breakers. Adjustable in-panel overloads per pump. Lead/lag alternation on every cycle, seal-in logic to full drawdown, a both-pump override for high inflow, and a separately fused high-water alarm that annunciates without calling a pump. Control power derived internally; no incoming neutral required.
QUICK START · MANUAL · SPEC · FIVE-SHEET SCHEMATIC SET
The balance of the series is built to specification: engineered to the motors it will start, fabricated to the submittal drawing, marked with its own ratings, and documented before it leaves Mims. A code inside the door opens the current documentation for that panel from the field, for the life of the panel.
