What is the IEC 60320 locking C19?

The locking C19 is the IEC 60320 female line connector (the cord-set / appliance-coupler side) that mates with a C20 connector, rated 16 A at 125/250 V with a 70 °C temperature class and a protective-earth contact on a 3-core earthed cable. It is typically used on servers, UPS systems and high-power IT or industrial loads on 16 A circuits.

How does the locking C19 connector stay connected?

A spring latch clicks over a matching locking C20 inlet so the coupling cannot shake or pull free under vibration; press the latch to release. It still inserts into an ordinary C20 inlet without latching, and the 16 A, 70 °C rating is unchanged.

What is the maximum current and approximate wattage of the locking C19?

The C19/C20 sheet is rated at 16 A; at 125/250 V that supports roughly 4000 W on a 250 V circuit or 2000 W on a 125 V circuit, subject to cord gauge and the wall plug. Use 1.5 mm² / 12 AWG or heavier for a full 16 A run.

What conductor sizes and cord types is the locking C19 supplied on?

It can be built on 3-core 0.5–1.5 mm² or 12–18 AWG conductors using H03VV-F, RVV, YZ, YZW, H05VV-F, H05RR-F; choose a heavier gauge for long runs or full-load equipment to avoid voltage drop and heating, and specify the wall-plug end for the destination country.

Can you change the opposite end on an IEC cord?

Yes, the opposite end can be stripped, tinned or terminated with a connector to your drawing. Each finish is shown in power cord wire end options .

IEC Power Cords, IEC 60320 C19 Locking Connector Plug, Type C19, 3 poles, 3 wires, UL, ETL, VDE, TUV, SAA, KC, PSE Certified

The Type C19 IEC power cord is a three-prong grounded high-current locking lead rated 16A, 20A, 125V/250V, that connects to an IEC 60320 C20 appliance inlet and cannot work loose under load. Produced to IEC 60320 C19 connector standards, it is offered with UL, ETL, VDE, TUV, SAA, KC and PSE approvals. The molded non-rewirable locking C19 head provides line, neutral and protective-earth contacts for safe earthing of power-hungry Class I equipment, and a built-in locking latch grips the C20 inlet against vibration, thermal movement and accidental tugging, then releases with a simple tool-free press. The matched heavy-duty flexible cord is available in thermoplastic PVC or crosslinked rubber insulation. These locking IEC power cords are widely deployed on servers, UPS units, storage arrays, large workstations and data-center power distribution. As a direct manufacturer we fully mold every locking C19 cord for reliability and tailor cable length, wire gauge and jacket color to each project; all meet RoHS and REACH requirements.

IEC 60320 is an international standard published by the International Electrotechnical Commission (IEC), titled "Appliance couplers for household and similar general purposes". It specifies the dimensional, electrical, and safety requirements for couplers used to connect power supply cords to electrical appliances, covering voltages up to 250 V a.c. and currents up to 16 A. The standard is divided into several parts, with the most important being IEC 60320-1 (General requirements), which has undergone multiple revisions: the first edition was published in 1994, the second in 2001, the third in 2015, and the latest effective edition is the fourth edition, IEC 60320-1:2021, released on 27 July 2021. Additional parts include IEC 60320-2-X series for specific applications (e.g., sewing machine couplers, couplers with higher IP ratings) and IEC 60320-3 for standard sheets and gauges.
