The series

The number tells you the voltage

Every 9000 Series panel is named the same way. Read the number and you know the service it is built for and how many motors it runs — before you open the door.

9100
230 / 240 V

The workhorse of the line. Commercial lift stations, pumping, irrigation.

9200
208 V

Built for 208 V building service — commercial and multi-family.

9300
460 / 480 V

Industrial and municipal service, larger motors and longer runs.

9400
600 V

600 V service, engineered to order.

9800
Phase conversion

Three-phase pumps on single-phase service. Single-phase in, drives out.

9···Nine thousand series — Legacy three-phase
·1··Second digit — the voltage class
··2·Third digit — motors: 1 simplex · 2 duplex · 3 triplex · 4 quadplex
···0Fourth digit — the drawing set

Horsepower never changes the number. A 230 V duplex for two 3 HP pumps and one for two 5 HP pumps are the same panel — same box, same layout, same drawing — with the starters and breakers sized to the motors.

Live logic

The drawing runs

This is the LC-9120’s documented float sequence, running. Raise the water and watch the panel do exactly what the operation manual says it does — seal in, draw down, alternate, force both, and alarm without ever calling a pump it should not.

ALARM
LEAD: PUMP 1 · SEAL-IN: OPEN · CYCLES: 0

Behaviour as documented: the ON float seals in through R1 until the OFF float opens — full drawdown, no cycling at the on level. The alternating relay swaps the lead every cycle. The high-water alarm is separately fused and calls no pump; silence mutes the audible only.

Motor protection

Protection is set, verified and documented

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.

Adjustable overloads

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.

Phase monitoring

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.

Configuration

Specified to the application

Control & sequence

Simplex, duplex, triplex and quadplex

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

Power & site

208, 230, 460 and 600 V three-phase, 60 Hz · 1–30 HP per motor

Phase conversion — single-phase service in, three-phase motors out

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

To specify a panel

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.

9800 · Phase conversion

No three-phase service? Run three-phase pumps anyway.

Farms, rural stations and remote sites often have single-phase power and a job that wants three-phase motors. The 9800 is built drive-ready: single-phase service in, drives out to three-phase pumps — built, marked and documented to the same standard as the rest of the series.

Every family, one standard

Built the Legacy way

Whatever the family, the same rules go into the box. That is what makes a panel built in Mims recognizable — to the inspector, to the service tech, and to us, years after it ships.

01UL 508A Listed shop

Every panel built and marked under the Listing, with a nameplate stating its own ratings.

02Serialized and traceable

Each unit carries its own serial and a build record. We know what is inside every panel we ship.

03Documented for life

A code inside the door opens that panel’s current documents on any phone. No login, no searching.

04X-Frame serviceable

The control assembly lifts out on quick-connects. Field terminations stay put while service happens on the bench.

05Coordinated protection

Overloads, branch breakers and control fuses plotted together, so each device clears in its own zone.

06Parts made in house

Breakers, floats, clamps and weights we manufacture ourselves — so our lead times hold.

Bring us the nameplates

Motor data, service voltage, sequence and site. A submittal drawing comes back before a panel is built.
