TOB163 3P 63A Mini Circuit Breaker C Type 3 Phase MCB 230/400V Threephase Overload Protection

3P AC MCB TOB163 C type 230/400V50HZ/60HZ Mini Circuit breaker (3P 63A) Key benefits Protects threephase circuits from overloads and short circuits to reduce downtime and prevent damage to wiring and connected equipment. C type trip curve handles moderate inrush currents, making it suitable for generalpurpose circuits with inductive loads. Wide range of rated currents lets you select the exact protection level you need, from small control circuits to larger feeders. Main features and specifications Model: TOB163, C type Poles: 3P (threepole) Rated voltage: 230/400V AC Frequency: 50HZ or 60HZ Rated current options: 3A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A Function: thermalmagnetic mini circuit breaker for overload and shortcircuit protection Form factor: mini circuit breaker format for threepole protection Why choose this breaker Precision protection: C type characteristic provides reliable tripping for circuits with typical motor and lighting inrush currents while still protecting against sustained overloads and short circuits. Flexible selection: available in multiple current ratings so you can match protection to cable and load requirements without oversizing. Threephase coverage: single device provides coordinated protection across all three phases, simplifying wiring and improving system reliability. Performance and compatibility Designed for use in AC threephase distribution at 230/400V and 50HZ or 60HZ systems. Suitable for typical electrical panels and distribution boards requiring threepole protection. Rated current range covers small control circuits through to main feeders up to 63A. Typical use scenarios 1) Small commercial distribution board: Protect threephase lighting and outlet circuits in retail or office spaces using a single compact 3P breaker for uniform protection. 2) Motor feeder protection: Protect small motors and pump units that produce moderate startup currents, leveraging the C type trip curve to avoid nuisance tripping during inrush. 3) Industrial subcircuits: Provide overcurrent protection for subdistribution lines feeding machine controls, compressors, or HVAC components within factories and workshops. Installation notes Select the rated current that matches cable ampacity and load requirements. Use one 3P TOB163 C type breaker per threephase circuit to ensure simultaneous disconnection of all phases. Ensure proper coordination with upstream protection devices when integrating into existing systems. This 3P AC MCB TOB163 C type 230/400V 50HZ/60HZ mini circuit breaker offers straightforward, reliable threepole protection with multiple current options for a wide range of threephase applications.
