Molded Case Circuit Breakers (MCCB)

Molded Case Circuit Breakers (MCCBs) – Smart Protection with High Performance

Our MCCBs are built to deliver powerful protection, advanced control, and flexible integration for modern electrical systems. Designed for reliability in demanding environments, these compact circuit breakers ensure space savings without compromising on safety or functionality.

Key Features

• Compact, Versatile Design
  Available in two standardized frame sizes, designed to optimize space in switchboards or wall-mounted installations. MCCBs can be mounted in any position for flexible integration.
• Wide Current Range
  Rated from 16 A up to 630 A to suit both light and heavy-duty applications.
• Multiple Breaking Capacities
  • Up to 250 A: 25, 36, 50, 70, 100, 150, 200 kA at 415 V
  • Up to 630 A: 36, 50, 70, 100, 150, 200 kA at 415 V
  • Both frames offer 75 & 100 kA at 690 V
• Available in Multiple Pole Configurations
  Options include 1-pole, 2-pole, 3-pole, and 4-pole variants for system compatibility.
• Advanced Protection Technologies
  Choice of electronic or thermal-magnetic trip units, offering precision protection and adaptability.
• Integrated Energy Monitoring
  Advanced trip units measure key parameters such as current (I), voltage (U), power (P), energy (E), total harmonic distortion (THD), frequency (f), and power factor (CosPhi).
• Smart Upgrade Path
  Interchangeable trip units allow for easy upgrades without replacing the entire breaker.
• Plug-and-Play Wiring & Accessories
  Modular design with field-installable auxiliaries, communication modules, and integrated earth leakage protection via optional MicroLogic Vigi (ELCB).

Benefits
