HMCB Benefits

• Extreme temperature protection: Operates reliably from -40 °C to +85 °C, maintaining constant trip ratings and protecting cables and equipment without the need for costly oversizing.
• Stable rating: Maintains 100 % rating capability regardless of ambient temperature.
• Precision tripping: Ideal for applications with sensitive equipment requiring precise tripping point protection.
• Robust Design: Build to last, even in the harshest of environments, reducing maintenance or replacement costs.
• Minimal Voltage Drop: Lower internal resistance compared to Thermal-magnetic circuit breakers, ideal for low voltage DC applications.
• Avoid Nuisance Tripping: Shock-resistant and reduces EMC/EMI noise micro-cuts.
• Harsh Environment Protection: Resistant to humidity and saline environments.
• Hot-Pluggable Design: Allows maintenance without shutting down the entire system.
• Integrated auxiliary alarm switch: Saves horizontal space and cost by eliminating the need for extra poles.
