The PFLD-NBK-S120M40A is engineered to handle full 400 A neutral duty with the reliability demanded by industrial and utility-scale power networks. Black insulation follows the Australian Standards (AS\/NZS 3000) and the legacy UK colour scheme (BS 3371), making this connector the standard choice for regional installations in Australia, New Zealand, and older UK infrastructure. Rated for 1000 volts AC or 1500 volts DC at dual 400 A\/660 A capacity, this drain interface line drain connector provides the low-impedance, fault-tolerant neutral path that modern power systems require.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e  \u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e 400 A \/ 660 A dual-rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 1000 V AC maximum \/ 1500 V DC maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWithstand Voltage:\u003c\/strong\u003e 4500 V test (three seconds)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort Circuit:\u003c\/strong\u003e 35.5 kilo-amperes symmetrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Resistance:\u003c\/strong\u003e Greater than 5000 MOhms at 500 V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Resistance:\u003c\/strong\u003e 0.1 mOhms nominal (at rated current)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e 45 to 85 °C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMating Cycles:\u003c\/strong\u003e 500 cycles minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection:\u003c\/strong\u003e IP67 when mated\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eStandards\u003c\/h3\u003e \u003cp\u003e\u003cstrong\u003eTÜV:\u003c\/strong\u003e Certified to TÜV standard 1111303479; \u003cstrong\u003eCE Marking:\u003c\/strong\u003e Compliant with European Union directive requirements; \u003cstrong\u003eRoHS Directive:\u003c\/strong\u003e Compliant with 2011\/65\/EU (Restriction of Hazardous Substances); \u003cstrong\u003eREACH Regulation:\u003c\/strong\u003e Registered and compliant with EC 1907\/2006 (Registration, Evaluation, Authorisation, and Restriction of Chemicals); \u003cstrong\u003eUL94-V0:\u003c\/strong\u003e Housing meets highest flame-resistance classification; \u003cstrong\u003eAS\/NZS 3000:\u003c\/strong\u003e Compliant with Australian and New Zealand electrical safety standard; \u003cstrong\u003eBS 3371:\u003c\/strong\u003e Historical UK colour code compliance for legacy infrastructure.

As the drain side of an inline cable connection, it receives the mating source contact and provides a sealed, IP67-rated junction when coupled. The black housing enables instant visual identification of the N conductor across cable runs. It is commonly deployed in touring theatrical production applications.

The ergonomic rubber grip section also carries the color, so technicians can identify the phase while handling the connector.

The housing material achieves a UL94-V0 flammability rating, which is the highest classification for vertical flame resistance in plastics, meaning the material self-extinguishes within 10 seconds with no flaming drips. The silicone O-ring seal contributes to the IP67 rating when mated, meaning the connection is fully protected against dust ingress and temporary immersion in water up to 1 meter for 30 minutes.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"kupo-faq-seo-item\"\u003e  \u003ch3\u003e Can PFLD-NBK-S120M40A be integrated into an existing power distribution system?\u003c\/h3\u003e  \u003cp\u003ePowerFit connectors are designed to be compatible with major brands of single-pole power connector.

Hammer the cotter pin in from its chamfered side for proper seating. Slide the cable with reduction sleeve into the contact, then tighten both set screws using a 5 mm hex key to a minimum of 10.5 N\/m. Finally, thread the cable gland back on. The M40 gland includes two rubber bushings (inner diameter 23 mm and 33 mm) for flexibility with different cable sizes. At 190 mm total length with a 32.5 mm body diameter, the Line Drain is the longest connector in the PowerFit family, providing ample space for cable management and a secure grip surface.\u003c\/p\u003e \u003c\/div\u003e\u003c\/section\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Who needs PFLD-NBK-S120M40A and what problem does it solve?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"PFLD-NBK-S120M40A is a KUPO PowerFit 400 A line drain connector with a black housing, designated for the Neutral (N) conductor under Australia and UK (Old, pre-2004) conventions. As the drain side of an inline cable connection, it receives the mating source contact and provides a sealed, IP67-rated junction when coupled. The black housing enables instant visual identification of the N conductor across cable runs. It is commonly deployed in touring theatrical production applications. Touring shows load in and load out of different venues on tight schedules, sometimes daily.\"}}, {\"@type\": \"Question\", \"name\": \"How much current can PFLD-NBK-S120M40A safely handle in continuous operation?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"PFLD-NBK-S120M40A is rated for 400 amperes continuous with 120 mm² cable, scaling to 660 amperes with 240 mm² cable.
