LT Electrical and Automation Panels
Sysnix engineers low-tension power and automation panels around the actual load list, fault level, control philosophy, site environment and maintenance requirements. Power distribution, motor control, PLC hardware, drives, protection and communication are coordinated as one documented panel system.
LT Control Panels capabilities
- PCC, MCC, APFC, AMF, VFD and PLC panel engineering
- Single-line diagrams, GA, schematics and terminal plans
- Busbar, protection, cable and thermal design inputs
- PLC, HMI, metering and communication integration
- Panel inspection, functional testing and FAT support
- Installation, cable checks and commissioning assistance
Typical applications
- Machine and process control panels
- Pump, fan and utility MCCs
- VFD and soft-starter panels
- Power distribution and APFC systems
- Water and wastewater panels
- Plant retrofit and panel replacement
Business and engineering outcomes
Safer maintainability
Clear segregation, device labeling, terminal planning and drawings help plant teams isolate and service circuits.
Application-matched protection
Loads, starting duty, fault inputs, environment and coordination requirements guide component selection.
Cleaner automation integration
PLC, drive, metering and communication hardware are planned with power and EMC considerations from the start.
Documented expansion
Spare capacity and as-built records make later additions more predictable.
Engineering and delivery approach
- Electrical inputs: Verify load list, motor data, incoming supply, fault-level inputs, cable details, environment and project standards.
- Detailed engineering: Prepare SLD, GA, power and control drawings, bill of material, terminal plans and panel heat considerations.
- Assembly and inspection: Check enclosure, busbar, wiring, earthing, labels, devices, clearances and drawing conformity.
- Functional testing: Test control power, protections, I/O, interlocks, communications and agreed FAT sequences before dispatch.
- Site integration: Support installation checks, cable termination verification, energization and commissioning.

Frequently asked questions
Which LT panels can you engineer?
Typical projects include PCC, MCC, APFC, AMF, VFD, soft-starter, PLC and remote-I/O panels. The final design depends on the approved load and project specification.
Do you provide panel drawings?
Yes. The agreed documentation can include SLD, GA, power and control schematics, terminal plans, cable schedules and bill of material.
Can an old control panel be replaced without changing the machine?
Often yes. We first survey the existing I/O, loads, interlocks, field wiring, space and shutdown constraints before planning the retrofit.
Are protection and busbar ratings project-specific?
Yes. Ratings must be selected from verified load, fault-level, installation, ambient and applicable project-standard inputs rather than a generic panel template.
