Delixi CD30 3P 63A Miniature Circuit Breaker

The Delixi CD30NL3-63 is a 3-pole 63A miniature circuit breaker manufactured to IEC 60898-1 and SASO-certified for the Saudi Arabian market. At the top end of the MCB current range, the 63A three-pole configuration serves as both a distribution incomer breaker for small three-phase sub-panels and a branch circuit device for three-phase motor and equipment feeders in commercial and light industrial applications. The Type C trip characteristic standard on the CD30NL3-63 handles the starting inrush of three-phase motors, air handling units, compressors, and pump starters typically fed at this current level, making it a versatile single protection device across a wide range of Saudi commercial and industrial applications.

The 63A 3-pole MCB occupies a critical position in the hierarchy of LV panel design: it is large enough to serve as the incomer to 32-way single-phase distribution boards yet small enough to fit within the physical constraints of a standard 12-module DIN rail section in a modular enclosure. For Saudi panel builders constructing distribution boards to serve commercial office floors, retail units, and light industrial bays, the CD30NL3-63 provides an economical three-phase incomer that carries SASO certification and IEC compliance documentation suitable for submission to the Saudi Electricity Company and to main contractor quality teams. The 6 kA interrupting capacity is appropriate for downstream positions fed via upstream MCCBs in the 100A to 400A range — the typical incomer arrangement in Riyadh and Jeddah commercial buildings connected to 11 kV/400 V SEC ring main substations.

Delixi's CD30 platform uses the same 17.5 mm per-pole pitch across all current ratings and pole configurations, meaning a 3-pole 63A breaker occupies a predictable 52.5 mm in the distribution board — a dimension that panel designers can rely on when laying out busbar systems and circuit schedules. The mechanical and electrical endurance ratings match those of the lower-current CD30 variants, and the same silver alloy contact technology ensures consistent arc quenching performance across the full 63A operating range. For contractors who have standardised on the CD30 family for single-pole circuits throughout a building, extending that standardisation to three-pole incomers via the CD30NL3-63 simplifies spares holding and maintenance training.

Razz Middle East supplies the CD30NL3-63 to panel builders, main contractors, and MEP subcontractors across Saudi Arabia. Our documentation package includes SASO certification, IEC 60898-1 compliance declarations, and technical data sheets in both English and Arabic — covering the full submission requirements for MOMRA-regulated building projects and for SEC new connection applications. We hold stock in Riyadh and Dammam and can advise on selection between the CD30NL3-63 and the CDM1-100M/3300 MCCB for applications where fault level or remote tripping requirements may push the design beyond the MCB category.
