EDFO （B Type）Residual Current Operated Circuit Breaker
Product Details
Product Descriprion
The EDFO series is a high-performance residual current-operated circuit breaker, specifically engineered to meet the safety and reliability requirements of demanding commercial, industrial, and infrastructure projects. It provides comprehensive protection against overload, short-circuit, and earth leakage faults, including smooth DC residual currents (B-Type), making it ideal for EV charging stations, data centers, and other high-tech installations. Key intelligent features include a trip cause indicator, which clearly shows whether a trip was caused by earth leakage (protrudes 3mm) or other faults, and a visual contact window that displays RED (ON) or GREEN (OFF) status for fast, safe maintenance—critical for minimizing downtime in large-scale operations.
Product Features
1. Type B Residual Current Protection (Critical for EV & Industrial Use)
Provides comprehensive protection against AC, pulsating DC, and smooth DC residual currents, meeting the specific requirements of EV charging stations, solar inverters, and industrial power systems.
2. Intelligent Fault Diagnosis for Reduced Downtime:
Earth leakage trip indicator (3mm protrusion) clearly identifies fault causes at a glance, paired with a visual contact position window (RED/GREEN status). This simplifies maintenance in large-scale installations, minimizing downtime for commercial and industrial projects.
3. High-Reliability Performance for Demanding Environments
Rated up to 80A with 4.5kA/6kA breaking capacity, operating reliably from -40°C to 70°C. Designed for long-term continuous use in harsh conditions, with high mechanical/electrical endurance to support bulk deployments.
