CHINT NC1-95 AC Contactor

The CHINT NC1-95 AC Contactor is a high-power 3-pole device rated at 95 A under AC3 duty and 150 A under AC1 duty, delivering 45 kW (60 HP) motor switching capacity at 415 V AC. Manufactured to IEC 60947-4-1 and SASO-certified for Saudi Arabia, the NC1-95 is the top tier of the NC1 contactor series — a heavy-duty family positioned above the NXC series for applications involving large motors, capacitor bank switching, and high-inrush loads. The coil is available in 220 V AC (50 Hz) standard configuration and optionally in 110 V AC or 24 V DC, with the coil consuming only 10 VA in steady-state hold mode — a feature that reduces heat generation in densely packed motor control centres and extends coil life in continuous-duty applications such as pumping and compressor stations where the contactor may energise for weeks without de-energising.

The NC1-95 uses a 3-phase arc chamber with deion grid arc extinction, specifically designed for the higher arc energy produced when interrupting 95 A AC3 currents. The arc chambers are user-replaceable field items, allowing maintenance teams to restore the contactor to OEM contact and arc chamber condition without replacing the entire device body — an economically important feature in large installations where a hundred-plus contactors are in service simultaneously. Auxiliary contacts follow the NC1 family standard: 1NO+1NE built in, with add-on blocks available to expand to 4NO+4NE, and the front face accepts CHINT's ET timing relay and LU1 suppressor modules that snap on without tools.

Saudi Arabia's oil and gas sector demands contactors in the 45–75 kW motor class for a wide range of process applications: sea water lift pump motors at ARAMCO's offshore and coastal facilities in the Eastern Province, large fire water system motor drivers at refinery and petrochemical sites, cooling water pump motors for heat exchangers in SABIC's process plants in Jubail, and large fan motors in waste heat recovery and process gas cooling systems. SWCC's large desalination plants — including the Jubail Phase 3, Al-Khobar, and Yanbu complexes — specify contactors in this class for high-pressure pump motors and brine recirculation drives, often in motor control centres built to IEC 61439-1 by local Saudi panel fabricators. NEOM's water and energy infrastructure, being constructed to the highest international standards for a smart city, specifies heavy-duty IEC contactors from qualified brands, and the NC1-95 with its SASO certification and CHINT's strong Saudi track record regularly appears on approved vendor lists submitted by international EPC contractors.

Razz Middle East maintains buffer stock of the NC1-95 in 220 V AC and 24 V DC coil variants at our Riyadh and Dammam facilities. We supply matching CHINT NXR-100 thermal overload relays (63–100 A) as complete starter packages, provide IEC test certificates and SASO documentation for government and ARAMCO procurement, and can arrange expedited delivery to SWCC complex sites, SABIC Jubail project offices, and NEOM logistics hubs within the Kingdom.
