Tronic MCCB 160 Amps 4 Pole Adjustable Circuit Breaker
TSh 141,500
Our review
This Tronic molded case circuit breaker is a four-pole unit rated at 160 amps, with adjustable trip settings. MCCBs like this sit between a fuse and a full air circuit breaker: they interrupt excessive current from overloads or short circuits, and the adjustable trip point lets you tune protection to the circuit rather than accepting a fixed threshold. The four-pole format suits three-phase installations where the neutral also needs switching or protection, common in distribution boards and feeder circuits. Before buying, confirm your system voltage and frequency fall within the breaker's range, check that 160 amps matches your load and cable sizing, and verify the trip setting range covers the protection curve you need. Compare against fixed-trip MCCBs, which are simpler but less flexible, and against fuse-based protection, which is cheaper but needs replacement after every fault. Also weigh frame size and whether your enclosure has room for a four-pole device. If your installation needs adjustable, resettable protection on a three-phase circuit, this is the type of breaker to shortlist; it is available on Sokonia.
