Product Description
Broadcast facilities and outside broadcast (OB) vehicles operating under Australian AS/NZS 3000 standards require red-coded L1 phase identification for reliable single-pole power routing. The PowerFit 400A Panel Source in red provides a permanent panel inlet rated for 400A continuous operation (660A with 240mm squared cable), featuring silver-plated brass contacts for minimal voltage drop across extended cable runs. The patent key-release pin allows tool-free disconnection during maintenance windows, and the non-conductive UL94-V0 thermoplastic housing ensures flame retardant protection in equipment-dense broadcast environments.

Compatibility
The PowerFit 400A Panel Source connector is compatible with major brands of single-pole power connector systems. Its M12 threaded post interface and push-and-twist mating mechanism with key-release pin ensure standardized connection geometry across certified suppliers. The male contact mates with PowerFit Line Drain and Panel Drain connectors. Verify mechanical and electrical specifications with your mating connector manufacturer to confirm impedance matching and safe operating parameters. Use the color-coded and mechanically keyed design as a visual safeguard to prevent cross-phase connection errors during installation or reconfiguration.

Frequently Asked Questions
PFPS-1R FAQ
How does PFPS-1R combine panel mounting with disconnect convenience?
PFPS-1R is a KUPO PowerFit 400A panel source connector with a red housing, identifying Line 1 (L1) under Australia conventions. Mounted permanently at generator outputs, main panels, and power supply enclosures, it is the origin point from which power flows outward through the PowerFit system. Despite being panel-mounted, it retains the key-release mechanism for convenient field disconnection. It is commonly deployed in film location shoot applications. On-location film production often runs power through variable terrain and weather conditions that studio stages never face.
What are the power handling specifications of PFPS-1R?
PFPS-1R is rated for 400 amperes continuous with 120mm2 cable, scaling to 660 amperes with 240mm2 cable. The maximum voltage rating is 1000V AC or 1500V DC. The insulation resistance exceeds 5000 megaohms at 500V AC, and the test voltage rating of 4500V AC provides substantial safety margin. The short circuit rating of up to 35.5 kiloamperes means the connector can withstand fault conditions without catastrophic failure.
What does the red housing on PFPS-1R represent under Australia standards?
Australian wiring standards designate red as the Line 1 (L1) conductor. The Australian three-phase color set is red (L1), white (L2), and blue (L3). Red L1 is also used in parts of New Zealand and some Asia-Pacific regions that follow Australian electrical practices. On the Panel Source, the red housing is visible on the connector face at the power origin point. Color coding at the source end of the distribution chain is especially important because phase assignment errors at the panel propagate through every downstream connection. Using the correct L1 color prevents phase rotation errors that can damage three-phase motors and sensitive equipment.
How is PFPS-1R certified for use as a power source connector?
PFPS-1R is TUV Rheinland certified (ID 1111303479) under Type Approval, Safety, and Regular Production Surveillance categories. It also carries CE marking, RoHS compliance (Restriction of Hazardous Substances), and REACH compliance. 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. As the power origin point, the Panel Source undergoes the same TUV safety evaluation as the full PowerFit system, including the key-release mechanism and panel-mount retention.
Can PFPS-1R work alongside connectors from other brands in a distribution panel?
PowerFit connectors are designed to be compatible with major brands of single-pole power connector. The IP67 rating means production does not stop for rain, and the push-and-twist connection resists accidental disconnection from cable tension or foot traffic across cable runs. For L1 circuits using Australia color conventions, the red PFPS-1R ensures that phase identification remains consistent when mixing PowerFit connectors with existing inventory.
