4 Pole Mini Circuit Breaker 16A B Curve 415V AC MCB 6kA Three Phase 4P Integrated Protection

4P Miniature Circuit Breaker, 16A, B Curve, 415V AC, 6kA breaking capacity Key benefits Protects circuits from overloads and short circuits in fourpole installations by automatically interrupting fault currents. B curve trip characteristic is suited to circuits with predominantly resistive loads and limited inrush current, reducing nuisance trips. Compact 4P design protects three phases and neutral in a single modular device, simplifying panel wiring and space use. What this product does Acts as a singlepole protection device for fourconductor 415V AC systems, providing reliable interruption of fault currents up to 6kA. Available in a range of current ratings including 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A, and with B curve or C curve trip characteristics to match application needs. The selected configuration is 4P with a B curve and rated at 16A. Key specifications Poles: 4P Rated voltage: 415V AC Rated current (selected): 16A Available current ratings: 6A through 63A Trip curves: B curve and C curve options Breaking capacity: 6kA Form factor: Miniature circuit breaker for modular panels Why customers choose this breaker Clear compatibility with fourpole, 415V AC distribution systems for compact and integrated protection. Multiple ratings and trip curves allow matching protection to circuit type and inrush characteristics. Single device protects all three phases plus neutral, reducing component count and wiring complexity. Practical applications Threephase distribution boards in small commercial and light industrial installations where coordinated protection for all phases and neutral is required. Protection of lighting and general power circuits with mainly resistive loads, where a B curve minimizes unnecessary tripping. Use as a phase and neutral protective device in subdistribution panels for apartments or small offices supplied with 415V threephase power. Installation and compatibility notes Designed for use in standard modular electrical panels and switchgear configured for 4pole breakers and 415V AC supply. Choose B curve for circuits with low inrush; choose C curve for circuits with higher motor or transformer inrush currents. Select the appropriate rated current from the available options to match conductor sizing and downstream load. This 4P 16A B curve AC MCB provides straightforward, modular protection for fourconductor 415V systems with a 6kA interruption capability and flexible rating options to suit a range of electrical installations.
