Q: What is an automated production line?

An automated production line integrates multiple machines and workstations to perform assembly and testing with minimal human intervention. Our MCCB line includes riveting, torque calibration, magnetic trip test, thermal calibration, hi-pot test, and ETU calibration.

Q: How does motorized MCCB work?

A motorized MCCB uses an electric motor to remotely open or close the breaker. Our lines can assemble and test motorized MCCBs, including motor operation verification.

Q: What is the full automatic production line?

A full automatic line performs all processes from feeding to final testing without manual intervention. Our MCCB line is fully automatic with conveyor, servo riveting, torque control, and inline testing.

Q: What is the difference between MCP and MCCB?

MCP provides short-circuit protection only (for motors), while MCCB provides both thermal overload and short-circuit protection. Our lines can assemble both types.

Q: What is ETU calibration?

ETU calibration verifies electronic trip curves (L-S-I-G) by injecting simulated fault currents and measuring trip times. Our line automates this and verifies Modbus communication.

Q: What is the typical payback period for an automatic MCCB line?

12-18 months for volumes above 50,000 units/year, from labor reduction, improved yield, and reduced field returns.

An assembly and testing line that works automatically for molded case circuit breakers where a number of different steps will take place, including the following processes: Riveting, Torque Calibration, Calibration of ETU Digitally, Hi-Potential Testing, and MES Traceability. Created to operate in a large quantity of products being created.

Core advantages

Why a fully automatic MCCB production line?

A fully automated production line for medium- to-large-size MCCB manufacturing eliminates manual bottlenecks and ensures consistent mechanical assembly. Additionally, each electrical assembly is traced back to an exact test conducted according to IEC 60947-2.

Full‑process automation

No manual handoff between stations – from case loading to ETU calibration. Reduces labor dependency by up to 70%.

Servo‑driven precision

Servo-controlled actuators for arc chute alignment and contact assembly – critical for consistent breaking capacity.

ETU digital calibration

Automated calibration of electronic trip units (L‑S‑I‑G curves) with Modbus communication verification.

MES traceability

Torque values, riveting forces, trip curves, and hi‑pot results linked to each unit’s serial number.

Integrated line modules

Our MCCB automatic production line components

Modular stations that form a complete assembly and test line for molded case circuit breakers.

Each module can be ordered separately or as a fully integrated line.

For an automatic line, the return on investment is less than 12 to 18 months if the production volume exceeds 50,000/unit/year. Determine your ROI here →

Design guide

How to specify an MCCB automatic production line – 5 steps

Plan your assembly and test line for maximum efficiency and future‑proofing.

Step 1: Define frame size range & volume

Determine your MCCB frames (100A‑1600A) and annual volume. This decides conveyor speed, station count, and tooling.

Step 2: List required assembly processes

Typical: case loading → riveting → torque calibration → mechanism assembly → arc chute insertion → cover closing.

Step 3: Specify electrical tests

Magnetic trip, thermal calibration, hi‑pot (dielectric), contact resistance, and ETU calibration for electronic breakers.

Step 4: Plan MES & traceability level

Barcode per unit, real‑time data upload (OPC UA / Modbus), SPC dashboards, and reject reason logging.

Step 5: Allow for quick changeover

If you produce multiple frame sizes, specify quick‑change tooling and recipe‑based parameters. Changeover under 60 minutes.

Got Questions?

MCCB Automated Production Line

What is an Automated Production Line?

An Automated Production Line consists of a series of machines and workstations that are connected together via a material handling system to complete assembly and testing with little or no manual labor. Our MCCB Automated Production Line consists of riveting, torque calibration, mag trip test, thermal calibration, Hi-Pot test, and ETU digital calibration all centrally PLC controlled and data logged to MES.

How does Motorized MCCB work?

Motorized MCCBs (Molded Case Circuit Breakers) use an electric motor versus manual handle to open or close the breaker remotely. These devices are used where remote tripping or automatic reclosing is desired. Our production lines can assemble and test all components of the motorized MCCBs and confirm operation of the motor and auxiliary contact status.

What is the Full Automatic Production Line?

Full Automatic Production Line means the entire manufacturing process from feeding of raw components until final testing are performed by machines with no manual intervention required. We have a complete MCCB assembly line: automatic loading, servo rivet assembly, controlled-torque screw assembly, magnetic testing of trip mechanisms, thermal calibration of thermal trips, high voltage testing of MCCB components, ETU calibration, and uploading of MES data all occur on a single conveyor. The operator simply monitors the equipment while feeding magazines of various component parts.

What is the difference between MCP and MCCB?

The motor circuit protector (MCP) is designed for short-circuit protection of motors with no thermal overload protection; instead, it relies on a thermal overload relay for that function. The molded case circuit breaker (MCCB) provides both thermal (overload) and magnetic (short-circuit) protection. Our production lines can produce both types – with or without the need for thermal calibration.

What is ETU Calibration?

The ETU (Electronic Trip Unit) calibration process verifies that the trip curve of an ETU matches its intended setup, measuring and verifying the trip time of simulated fault currents and confirming Modbus communication automatically.

What is the typical payback period for an Automatic MCCB Line?

A production facility producing 50,000 MCCBs per year could expect less than 12 to 18 months to pay back investment in fully automated assembly versus semi-automated – through labor savings (60%-70%), higher first-pass yields (94%-99.5%) and lower field returns.
