FAZ-B16/3 — Eaton FAZ-NA xEffect Miniature Circuit Breaker
The Eaton FAZ-NA xEffect Miniature Circuit Breaker is a premium industrial MCB covering current ratings from 1 A to 63 A in 1, 2, 3, and 4-pole configurations, with a market-leading 10 kA breaking capacity at 480 V AC — twice the breaking capacity of standard residential MCBs and a critical advantage in industrial distribution panels where high fault-level busbars demand higher-rated protective devices. The FAZ-B16/3 is a 3-pole 16 A B-curve breaker rated for 10 kA breaking capacity, suitable for protection of three-phase industrial loads including motor feeders, transformer secondaries, instrumentation panels, and control panels in process facilities across Saudi Arabia, where industrial LV distribution fault levels routinely exceed the 6 kA breaking capacity of standard commercial MCBs.
The FAZ's xEffect contact technology provides exceptionally consistent and repeatable trip characteristics throughout its operational lifetime — Eaton's testing demonstrates that FAZ breaking capacity and trip-time performance remain within specification for the full rated mechanical and electrical lifetime of 20,000 operations. This consistency is particularly valuable in ARAMCO and SABIC safety and control panel applications where protective device coordination must be verified at commissioning and then assumed to remain valid for the operating lifetime of the installation without requiring periodic re-testing. The FAZ's magnetic tripping element covers B-curve (3–5x In), C-curve (5–10x In), and D-curve (10–20x In) variants, providing the application flexibility to serve as both motor feeder protection (D-curve, handling high locked-rotor current) and lighting and resistive load branch protection (B-curve) within a single standardised MCB platform.
The FAZ is designed for installation in Eaton's XPOLE and BD4 distribution boards, or directly on DIN rail, and includes front-face auxiliary contact sockets compatible with AT and AZ series auxiliary contact modules — enabling remote trip indication and remote reset without replacing the base MCB unit. The auxiliary contact system integrates with Eaton's SmartWire-DT flat-cable wiring solution for MCBs, reducing distribution board wiring complexity to a single cable connection per breaker and dramatically cutting panel assembly time on multi-breaker distribution boards in NEOM and Red Sea Project fast-track fit-out packages.
Razz Middle East stocks FAZ-NA in the full current rating and curve range from 1 A to 63 A in B, C, and D curves, 1-pole through 4-pole configurations. We supply distribution board builders, panel integrators, industrial construction contractors, and MEP engineers across Saudi Arabia. SAR pricing available with same-day quotation. Delivery from our Riyadh and Dammam warehouses.

Key Features & Benefits
- 10 kA breaking capacity at 480 V AC — twice that of standard commercial MCBs — handles high fault-level industrial LV busbars in ARAMCO, SABIC, and major industrial consumer distribution panels.
- xEffect contact technology maintains consistent trip characteristics within specification for 20,000 mechanical operations, eliminating drift in protective device coordination over installation lifetime.
- B, C, and D trip curve variants on a single standardised platform provide application flexibility from sensitive instrument feeder protection (B-curve) through motor feeder protection (D-curve) on one stocked MCB range.
- Front-face auxiliary contact socket (AT/AZ series) enables remote trip indication and remote reset without replacing the MCB body — supporting integration into building automation and SCADA alarm systems.
- SmartWire-DT compatibility reduces distribution board wiring to a single flat cable per breaker, cutting panel assembly time on multi-breaker boards for fast-track NEOM and Red Sea Project fit-out packages.
- 4-pole configuration option provides neutral conductor protection on TN-S distribution systems specified by Saudi electrical code for new industrial and commercial building installations.
Industrial Applications in Saudi Arabia
- Industrial distribution panel branch protection in ARAMCO and SABIC process facilities, where 10 kA breaking capacity handles prospective fault currents on high-available-fault-level LV busbars.
- Control panel and instrumentation panel MCB protection in oil and gas facilities, where FAZ B-curve consistent trip characteristics ensure reliable protection coordination with upstream fuses and MCCBs.
- Motor feeder branch protection in MCC panel incomer sections using D-curve FAZ breakers, where the 10–20x magnetic threshold accommodates locked-rotor current without nuisance tripping.
- NEOM smart district and commercial building distribution boards, where SmartWire-DT compatibility enables remote MCB status monitoring via the building management and IoT infrastructure.
- Transformer secondary distribution boards in substation LV panels at SEC-connected industrial consumer facilities, where 10 kA breaking capacity at 480 V matches transformer impedance fault levels.
- Lighting, small power, and general service distribution in government and commercial building electrical panels where D-curve and C-curve variants protect mixed resistive and inductive load branches.
