Tronic Four Pole 20A MCB, 415V AC
TSh 40,500
Our review
This is a four pole miniature circuit breaker from Tronic, rated at 20 amps and 415 volts AC, with a white PVC body and a one year warranty. Four pole breakers like this are normally chosen for three phase circuits where all live conductors need to trip together, so it suits someone wiring or protecting a three phase distribution board rather than a simple single phase home circuit. Before buying, confirm your supply is genuinely three phase and that 20A matches the cable and load it will protect, since the breaker rating should sit below the cable's current capacity. Also check the pole count and voltage rating match your panel and that the physical width fits your enclosure. Compare against other four pole MCBs by breaking capacity, trip curve and terminal size, since those details decide whether it is right for your installation. A licensed electrician should confirm suitability and install it.
