BD1-63S 2P
CHNAILE
The CHNAILE BD1-63S 2P is a heavy-duty, CE-certified miniature circuit breaker specifically engineered for high-demand single-phase (L+N) and two-phase 400V electrical systems. Featuring a robust 32A continuous load rating and dependable 6kA breaking capacity, it delivers essential simultaneous 2-pole disconnection for absolute electrical safety. Fully compliant with IEC60898-1 international standards, this breaker is the industry-standard protection solution for Level 2 EV charging stations, commercial HVAC systems, and high-draw industrial appliances. Its standard 35mm DIN-rail design enables rapid, tool-free installation for electrical contractors and panel builders worldwide.
Simultaneous 2-Pole Disconnect: Equipped with an internal common trip mechanism that instantly severs both Live and Neutral lines during faults. This eliminates dangerous return current hazards, ensuring 100% electrical isolation for maintenance crews and preventing damage to expensive connected equipment.
Precision Overload Protection: A finely calibrated bi-metallic strip accurately detects sustained overcurrents from heavy loads like EV chargers and commercial ovens. It trips at the exact threshold to prevent wire insulation degradation and potential fire risks without nuisance tripping.
Short Circuit Quick Break: A highly responsive electromagnetic tripping system extinguishes massive fault currents up to 6000A (6kA) in milliseconds, effectively stopping electrical arcs and protecting entire distribution panels from catastrophic failure.
V0-Grade Flame Retardant Housing: Encased in a rugged thermosetting plastic case that meets the highest fire safety standards. It dissipates heat efficiently during continuous 32A operation, preventing combustion even under extreme thermal stress.
High-Purity Copper Components: Oversized internal contacts and heavy-duty screw terminals are forged from high-conductivity copper. This minimizes electrical resistance and voltage drop, ensuring reliable performance and extended service life in high-load applications.
Vibration-Resistant DIN-Rail Mounting: Features a heavy-duty spring clip that provides a secure, shake-proof connection to standard 35mm DIN rails. This makes it ideal for industrial environments and mobile EV charging applications.
Reliable 6kA Breaking Capacity: Confidently handles severe fault currents common in commercial and industrial electrical systems, offering exceptional cost-effectiveness compared to higher-rated breakers for most applications.
Clear Visual Status Indication: The distinctive light-green toggle switch provides immediate visual confirmation of circuit status. Operators can instantly verify complete isolation at a glance, reducing human error during maintenance procedures.
