Tronic 63A Three Phase Circuit Breaker, 4-Pole, AC 240V

Our review

This Tronic unit is a four-pole circuit breaker rated at 63A with an operating voltage of AC 240V, housed in a white PVC body. The four-pole layout means it can switch or protect three phases together with a neutral, which is why it is usually chosen for three-phase distribution boards rather than single-phase household circuits. It suits electricians and installers working on small commercial premises, workshops or pump and motor panels where a 63A three-phase feed needs a single protective device. Before buying, confirm your supply is genuinely three-phase and that 63A matches the cable and load it will protect, since a breaker that is too large will not trip when it should. Check the mounting style and terminal arrangement of your existing board, because the listing gives no dimensions or breaking capacity, and compare against alternatives on poles, rated current and voltage. If you need surge or residual current protection, this device alone will not provide it. Available on Sokonia.
