CHINT NXB-63 Miniature Circuit Breaker
The CHINT NXB-63 Miniature Circuit Breaker is a compact, high-performance overcurrent and short-circuit protection device covering the 6 A to 63 A range in 1-pole, 2-pole, 3-pole, and 4-pole configurations. Manufactured to IEC 60898-1 and GB 10963 standards, the NXB-63 carries SASO certification for sale and installation in the Kingdom of Saudi Arabia, making it a fully compliant choice for commercial and light-industrial wiring projects overseen by SEC-approved electrical contractors. The device features a 6 kA rated short-circuit breaking capacity at 230/400 V, a tripping characteristic available in Type B (3–5 In), Type C (5–10 In), and Type D (10–20 In), and a mechanical and electrical endurance of 20,000 and 10,000 operations respectively — figures that match or exceed many European-branded equivalents at a substantially lower landed cost in Saudi Arabia.
CHINT designed the NXB-63 with a DIN-rail-mounted modular body that snaps securely onto standard 35 mm symmetrical rails without additional fasteners, simplifying panel assembly in distribution boards, motor control centres, and sub-distribution panels. The toggle handle provides clear ON/OFF/TRIPPED indication visible from a distance, and the terminal screws accept conductors from 1.5 mm² to 25 mm² with no need for ferrules in most domestic wiring applications. The slim 17.8 mm per pole pitch allows up to 18 poles to be installed in a standard 6-way domestic board without exceeding the board's busbar length, a detail panel builders and electrical contractors across Riyadh and Jeddah consistently appreciate when space inside flush-mounted consumer units is limited.
In Saudi Arabia, the NXB-63 has become the circuit breaker of choice for developers and electrical subcontractors working on mid-rise residential buildings, retail fit-outs, school campuses, and light-industrial facilities in industrial cities managed by MODON across Riyadh, Dammam, Jubail, Yanbu, Jeddah, and Mecca. Vision 2030 social-infrastructure projects — including new schools, hospitals, and housing clusters being built at pace across the Kingdom — routinely specify SASO-certified MCBs from reputable brands, and the NXB-63 competes directly on technical merit while offering cost savings of 25–40% compared to premium European brands, allowing project budgets to be allocated to higher-value items. SABIC contractor projects in Jubail Industrial City use the NXB-63 in auxiliary panel wiring where SEC arc-fault requirements do not apply.
Razz Middle East is the authorised Saudi distributor for CHINT electrical products, maintaining large local stock of all NXB-63 pole configurations and trip characteristics at our Riyadh and Dammam warehouses. We respond to RFQs within 4 hours with SAR pricing, offer contractor credit accounts, and provide same-week delivery to Riyadh, Jeddah, Dammam, Al Khobar, Jubail, Yanbu, Mecca, and Medina. Full IEC test certificates and SASO conformity documentation are available on request for MOMRA-registered electrical contractors and government procurement officers.

Key Features & Benefits
- SASO-certified and IEC 60898-1 compliant, meeting all Saudi Electricity Company (SEC) requirements for MCB installation in residential and light-commercial distribution boards across the Kingdom.
- 6 kA short-circuit breaking capacity at 230/400 V AC provides reliable protection against fault currents typical in commercial and light-industrial LV networks without requiring a separate back-up fuse in most installations.
- Available in Type B, C, and D tripping characteristics to match inductive, resistive, and high-inrush loads such as motors, transformers, and LED lighting drivers on a single product family.
- Slim 17.8 mm per-pole pitch allows maximum circuit density in DIN-rail panels, fitting up to 18 poles in a standard enclosure — a critical advantage for space-constrained distribution boards in residential and retail projects.
- Robust toggle handle provides unambiguous ON / OFF / TRIPPED indication visible at a glance, reducing troubleshooting time during electrical inspections and fault-finding call-outs.
- Terminal screws accept 1.5 mm² to 25 mm² conductors without ferrules, simplifying panel wiring and reducing installation labour time for electrical subcontractors on large residential projects.
Industrial Applications in Saudi Arabia
- Final-circuit overcurrent protection in residential apartment blocks and villa compounds across Riyadh, Jeddah, Mecca, and Medina where SASO-certified MCBs are mandatory under Saudi electrical codes.
- Sub-distribution panels in retail shopping centres and commercial fit-outs throughout the Kingdom, where the NXB-63's low unit cost allows full circuit-level protection without budget overruns.
- Auxiliary panel wiring in SABIC and ARAMCO contractor projects in Jubail Industrial City and Yanbu, where cost-effective SASO-compliant MCBs are acceptable for non-critical instrumentation and lighting circuits.
- School and hospital campus electrical distribution under Vision 2030 social-infrastructure programmes, where procurement officers require both SASO conformity documentation and competitive SAR pricing.
- Light-industrial facility wiring in MODON-managed industrial estates across Dammam, Al Khobar, and Jubail, where Type C MCBs protect motor-starter circuits against inrush currents without nuisance tripping.
- Consumer unit upgrades in municipal and government buildings managed by NWC and SWCC, where cost-efficient SASO-certified components enable large-scale refurbishment programmes within approved capital budgets.
