SENTOP Product Series
Electrical product series for panels, equipment and power distribution
Explore SENTOP terminal blocks, transfer switches, digital panel meters and supporting low-voltage protection, control and distribution products by their function in the electrical system.
Core Product Systems
Start with the function the product must perform
These three ranges are at the center of SENTOP's current electrical business. Use the system task first, then confirm ratings, dimensions, wiring, accessories and installation conditions.
Build an organized terminal strip around the conductor and circuit function
Choose the connection technology, terminal function and accessory system together. Conductor range, current, voltage, terminal width, DIN rail, bridge positions, markers, end plates and PE terminals all affect the final assembly.
Automatic & Manual Transfer Switches
Match the operating method to the source system, then confirm rated current, voltage, poles, neutral treatment, transfer duty, controller and installation.
Digital Panel Meters
Select by measured quantity, AC or DC system, direct or transformer input, range, auxiliary supply, panel cutout, accuracy, outputs and communication.
Low-Voltage Protection
Choose protection from the actual electrical system
Protection products are supporting business lines that can be supplied alone or as part of a panel and project BOM. Final selection must follow the exact system and target market.
Miniature Circuit Breakers
DIN rail overcurrent and short-circuit protection for final circuits and equipment.

DC Isolator Switches
Manual DC disconnection for photovoltaic, battery and other DC equipment circuits.
Explore DC Isolators →Control & Distribution
Supporting components for electrical cabinets and equipment
Choose these products from their role in the control circuit, load circuit or enclosure. Electrical ratings, terminals, dimensions, heat, mounting and environment still require model-specific confirmation.
Switching Power Supplies
AC-DC power supply directions for control circuits, equipment, displays and auxiliary loads.

AC Contactors
Electromagnetic switching directions for motors, heating, lighting and controlled loads.
Explore AC Contactors →
Distribution Boxes
Empty and configured enclosure directions selected by circuit schedule, devices and installation.

Five data groups make product matching faster
A useful request does not need to begin with an exact SENTOP model. Start with the information already available.
Product & Project Review
Send a model, photo, drawing, specification or BOM
SENTOP can review the product direction, identify missing selection data and organize related product requirements before quotation, sample confirmation or bulk ordering.
