DPX³ MCCBs up to 1600 A · DMX³ ACBs in three frame sizes · LV main and feeder switchgear
DPX³ and DMX³ are Legrand's heavy-protection families: the MCCBs and Air Circuit Breakers that sit at the LV-panel main and on the heavy outgoing feeders. Above DX³ on the panel hierarchy, coordinated through Legrand's published selectivity tables so an upstream DPX³ trip clears the fault before the downstream DX³ MCB sees it.
Specified on industrial mains, commercial-building incomers, hospital landing distributions, township DBs and panel-builder switchgear. Stocked through the authorised channel for panel-builder, contractor and industrial facility volumes.
DPX³ covers the MCCB tier: moulded-case breakers in three frame sizes through 1600 A. DMX³ covers the ACB tier: air circuit breakers for industrial mains.
Moulded-case circuit breakers in 160 A, 250 A, 630 A and 1600 A frame sizes. Thermal-magnetic and electronic trip-unit variants: LSI / LSIG / electronic with current and earth-fault settings. For the main incoming and outgoing of LV panels.
Air circuit breakers in three frame sizes, fixed and draw-out variants. For the main incoming of large industrial panels, township main DBs, hospital substation outgoings. Microprocessor trip units with full LSIG protection and communication options.
Auxiliary contacts, shunt trips, undervoltage releases, motor-operating mechanisms, rotary handles, key locks, padlock interlocks, the supporting hardware that turns a bare DPX³ or DMX³ into a working main breaker.
DPX³ MCCB variants with motor-protection trip curves, designed for the inrush current of large industrial motors. For pump-house panels, compressor mains, lift-shaft incomers.
DPX³ MCCBs sit at the LV-panel main and on the heavy outgoing feeders, typically 160 A or 250 A on a commercial building main, 630 A or 1600 A on an industrial main. DMX³ ACBs sit one tier higher, on industrial mains where the breaking capacity, draw-out maintainability, and microprocessor trip-unit features matter. Below both sit DX³ MCBs on the modular outgoings, coordinated through Legrand's published selectivity tables.
