IEC Connectors

What is an IEC Connector?

An IEC connector is an electronic cable that meets the International Electrotechnical Commission (IEC) standards. The specification for IEC connectors is IEC-60320. The connectors mounted with wires are referred to as female connectors or sockets. The connectors mounted with panels are known as male connectors or plugs. Connectors are available in various lead lengths and plug types.

NR520R Receptable, NEMA-Mains Socket Outlet

  • High Performance 20 A / 125 VAC up to 150°C
  • Snap-In and IDC-Terminals efficient installations.
  • Available in black, white and grey
Schurter Nr520r

The Schurter NR520R mains socket outlet, as an additional variant to the NR010, NR020 and NR021 models, represents an even more powerful performance to the NEMA mains socket outlet portfolio. The new NR520R complies with UL 498 and CSA C22.2 no. 42.

The higher load capacity of 20 A at 125 VAC makes the NR520R particularly suitable for demanding applications where both high performance and temperature resistance up to 150°C are required. The NR520R mains sockets are ideal for applications in data centers, telecommunications, power distribution and energy management.

Simple Installation, Maximum Safety

The new NR520R power sockets from SCHURTER are designed for particularly efficient snap-in installation and can be wired particularly quickly and easily thanks to IDC and Quick Connect terminals. With these features, the NR520R combines the highest safety and performance standards with time-saving and user-friendly installation. This is particularly interesting for manufacturers of power distribution products. After all: safe, effective and efficient.

Black, White or Gray

The NR520R from Schurter is available in three different colors: black, grey and white. These color options not only offer aesthetic advantages, but also enable targeted adaptation to different environments and areas of application.
