Product Description

The Mitsubishi WS Series MCCB (Molded Case Circuit Breaker) is a globally standardized low-voltage protection device designed for efficient circuit control and automatic interruption of overcurrents (overload/short-circuit). Manufactured in China with Mitsubishi Electric's stringent quality assurance, this series combines decades of technical expertise to deliver superior breaking performance, user-friendly operation, and compliance with international safety standards.

Standard Features

It features modular accessories, smart trip units, and robust construction suitable for diverse industrial environments, ensuring reliable power distribution and equipment protection

  • High Breaking Capacity: Advanced arc-quenching technologies (e.g., PA auto-blast, JPT gas pressure trip) for exceptional short-circuit interruption

  • Accessory Standardization: Supports plug-in modules like alarm switches (AX/AL), shunt trips (SHT), and undervoltage releases (UVT) for flexible integration

  • Dual Trip Systems: Interchangeable thermal-magnetic and electronic trip units for adjustable protection

  • Temperature Resilience: Operates at -5°C to +40°C (derating applied above 40°C)

  • Compact & Smart Design: Modular structure with communication-ready capabilities for grid automation
