Smart MCCB for Industrial Power Systems

Designed to prevent production losses from unplanned downtime, our Smart MCCB delivers fast fault isolation and auto power recovery for continuous operation.

Smart MCCB Placement in Industrial Power Systems

Installed in main & sub-distribution cabinets to protect production lines, motors and frequency converters.

Why This Placement Matters

  • Distributed architecture enables fast fault isolation without plant-wide shutdown
  • Reduce unplanned downtime by over 85%
  • Protect high-value motors & production equipment
  • Stop fault propagation across workshops
  • Coordinate protection between incoming & branch circuits
  • Unlike conventional breakers, Smart MCCB traps faults before they reach upstream circuits.

Pain Points &Traditional Limits

Core Challenges for Factory Operators

  1. Mixed motor & VFD circuits trigger false trips with vague protection boundaries
  2. Single branch faults cascade into full-line shutdowns
  3. Transient faults demand on-site manual reset and extend downtime
  4. Aging cabinets lack space for renovation & expansion
  5. Plant expansion requires scalable protection architecture

Why Conventional Breakers Fall Short

  1. No real-time remote data, slow fault response
  2. Hard to coordinate upper & lower protection parameters
  3. Maintenance / upgrades require full power cut
  4. Separate protection / metering / control devices lift total costs

Solution ModulesContinuous Production with Smart MCCB

Safety-gated automatic reclosing flow from trip record through interlock checks to stable restoration or lockout
Module 01

Automatic Reclosing

Restore power fast to cut downtime.

Over 80% industrial outages stem from transient faults. Smart MCCB auto-recloses after an adjustable 20–60s delay without manual work.

Fault → Trip → Delay → Auto Reclose → Production Restart.

  • Cut transient fault downtime by over 90%.
  • Eliminate on-site reset visits.
  • Sustain continuous core production.
  • Only activates for transient faults; locks open for permanent faults.

Remote Monitoring

Plant-wide central monitoring for predictive maintenance.

  1. All models support RS485 Modbus; carrier communication optional. Compatible with BMS/SCADA/MES for real-time voltage, current, power and fault alerts.
  2. Precise real-time fault positioning.
  3. Historical data for energy-saving analysis.
  4. Remote parameter & firmware updates.
  5. Early failure warning.

Full-Dimension Protection

Complete protection suite for harsh industrial environments.

  1. 3-stage protection: overload / short delay / instantaneous short-circuit.
  2. Overvoltage, undervoltage & phase loss protection.
  3. 30–1000mA adjustable leakage protection.
  4. Anti-motor inrush trip function.

ProjectFAQs

Which model suits regular production branch protection?

TDK3ELJ is the regular baseline where branch protection, leakage monitoring, communication, metering, and automatic reclosing are required. Final selection must confirm current rating, breaking capacity, and coordination settings.

What model for old factories with narrow cabinets?

TDK5EL is designed for compact retrofit installations. Cabinet dimensions, conductor routing, heat dissipation, current rating, and breaking capacity must still be checked before selection.

Can single unit cover protection & energy metering?

Yes. Metering models such as TDK4ELJ combine protection with voltage, current, power, energy, and power-factor data. Leakage and harmonic functions depend on the selected model.

Compatible with existing factory BMS/SCADA?

Yes. Smart MCCBs communicate over an RS485 field bus. A gateway or protocol converter provides the boundary to Ethernet and the plant BMS, SCADA, MES, or EMS platform.

Is auto reclosing safe for critical loads?

Reclosing is appropriate only for approved circuits and processes. The selected model, fault state, configured delay, electrical interlocks, and process permissions must all allow restoration; otherwise the breaker remains open for inspection.
