Franklin Electric E-tech SubTronic3P® range covers all 4" 3-phase motors from 0.37 kW to 7.5 kW. Ergonomic design, attention to detail and unique features make the SubTronic3P® range your first choice when considering submersible motor protection and management. Together with Franklin Electric submersible motors you have an undisputable advantage, resulting in ease of installation, sophisticated system management and peace of mind.
Specifications
- The SubTronic3P® range of control boxes has been designed as drop-in replacements for conventional 3-phase motor control boxes. As such, it will work with standard pressure/flow switches adding intelligence & protection to the borehole water system
- You get a complete package - the control box is 100 % compatible with Franklin Electric submersible motors, especially when you need protection and management of your borehole installation
- It‘s all in a name – now you have complete reliability and intelligence in your borehole, backed by the leader in submersible motors
Ergonomically Designed:
- Mounting: easy wall mounting offering various options without destroying the protection rating of the enclosure
- Wiring: reliable connectors are provided for ease of wiring
Motor Compatible Design:
- Matching range: the SubTronic3P® Protector range was designed to match the Franklin Electric range of 3 phase motors
- Wide range of operation: compatibility with motor design allows for a wide range of operation resulting in minimized nuisance tripping
Intelligent Protection and Management Features:
- Dry-run detection (without probes): prevents motor and pump damage due to running the pump without water based on a proprietary reliable detection method
- Dry-run auto- reset: automatic dry-run reset time is based on a proprietary search algorithm to find the best operating point for weak wells. Reset time in max. 60 minutes
- Over & under voltage: prevents motor damage that may be caused by abnormal voltage conditions without limiting the range of operation, made possible by matching the design of the SubTronic3P® Protector with the motor. Reset time approximately 3 minutes
- Over current protection: prevents operation under conditions where motor current may exceed safe levels due to bound pump or other fault condition. Detection is based on current heating capacity measurement to prevent unnecessary nuisance tripping. Auto-reset in 15 minutes. Manual reset possible in approximately 5 minutes by reapplying power
- Rapid cycle protection: prevents system damage due to factors such as continuous rapid cycling and excessive motor thermal cycling caused by waterlogged tank, faulty contacts or faulty pressure switch. Auto-reset in 5 minutes if condition clears. Manual reset possible in approximately 5 minutes by reapplying power
Indicators
- Status: indication shows normal operation or other condition
- Voltage: faulty voltage condition is indicated
- Fault conditions: dry-run, over Current, rapid cycling, overvoltage and undervoltage are indicated
