Tronic Industrial 4-Pole Circuit Breaker 100A 18kA MCCB
TSh 134,000
Our review
This is a moulded case circuit breaker from Tronic, built as a four-pole unit rated at 100A with a short-circuit breaking capacity of 18kA at 400/415V. That combination points to three-phase work: factory distribution boards, commercial building panels, and infrastructure installations where a fault needs to be cleared before it damages cables or connected equipment. It suits electricians, facility managers, and contractors specifying protection for a three-phase feeder rather than anyone working on a single-phase domestic board.
Before buying, confirm three things against your design: the tripping characteristics and settings your installation requires, the physical frame size and mounting arrangement of your panel, and whether your supply's prospective fault level sits within the 18kA rating. Those details are not listed here, so check them with the seller or the manufacturer's documentation. Compare against other 100A four-pole MCCBs on breaking capacity, adjustable settings, and terminal accessibility, since those often separate industrial-grade units from lighter alternatives.
