40A 3P Plug Base Circuit Breaker with Fast Arc Interruption and Reliable Threepole Protection

Model NDB163C Plug Base Circuit Breaker Overview A plug base circuit breaker intended for threepole leakage protection and rapid fault interruption. The unit uses a magnetic blowing arc breaker mode to interrupt arcs quickly and reduce fault duration. Compact and suitable for plugin applications where a 3P leakage protector is required. Key benefits Reliable threepole leakage protection: Leakage protector type 3P and number of poles 3P provide coordinated protection for threephase circuits. Fast arc interruption: Magnetic blowing arc breaker mode delivers rapid arc extinguishing for better fault response in shortcircuit and overload conditions. Easy replacement and maintenance: Plug base format simplifies installation and replacement without complex rewiring. Clear specification for matching: Size 40A and rated current 10A are specified for accurate selection and compatibility with existing electrical systems. Consistent functional performance: Engineered to handle typical plugin distribution board requirements for industrial and commercial circuits. Important attributes Model: NDB163C Color: 4P Size: 40A Number of poles: 3P Leakage protector type: 3P Rated current: 10A Arc mode: Magnetic Blowing Arc Breaker Performance and compatibility Designed to work in threephase plugin breaker bases and distribution panels that accept NDB163C form factor. Rated current and size information help ensure correct coordination with upstream protection and downstream loads. Magnetic blowing arc interruption provides a fast mechanical response suitable for protecting wiring and equipment from energy faults. Typical applications Threephase distribution boards in light industrial settings where a compact plug base breaker is required for branch circuit protection. Motor control circuits where quick magnetic interruption helps limit damage from short circuits and severe overloads. Retrofit projects replacing existing plugin breakers to achieve consistent threepole leakage protection and faster arc interruption. Installation notes Verify physical compatibility of the NDB163C plug base with the panel or socket before installation. Confirm selection of size 40A and rated current 10A meet the needs of the circuit and upstream coordination. Follow local electrical codes and standard wiring practices when installing or replacing the breaker. This description reflects the supplied product specifications and functions for the NDB163C plug base circuit breaker.
