C21 cable with Schuko plug
The IEC Lock PCS Power Cable Set C21 is a lockable power cord set for applications where the power connection must not be accidentally disconnected, such as in racks, UPS and PDU environments, or other technical installations. It is rated for IEC 320 C21, specified at 16 A / 250 V and available in various lengths and colors.
What’s special about it
The core benefit is the locking: The cable sits more securely in the device mounting socket and cannot slip out so easily due to pull or vibration. This is especially useful in data centers, broadcast environments, and medical devices, where unintentional interruptions can be problematic.
What is it suitable for?
Such cables are typically used when higher currents and particularly safe power supply are required, for example in servers, storage technology, PDUs or other devices with higher power requirements. IEC lock products are generally designed to prevent accidental pulling and keep the connection stable in the event of movement or vibration.
- Server racks and network distribution
- UPS Environments
- Devices that require special protection against cable pulling
- Wherever vibration is a problem and unintentional disconnection can become critical
IEC Lock products are intended for trigger-proof connections.
What to look out for
The compatibility of the socket on the device is important: The C21 cable does not fit arbitrarily, but only to suitable C20/C22 device connections.
Practical benefits
If you’ve ever had an easily loosened IEC plug in the rack, the advantage is immediately clear: the cable remains mechanically more securely connected and reduces failures due to pulling, vibration or conversions. Especially in professional IT and technical environments, this is usually the main reason for the use of such locking cables.
Advantages over standard cables
The main advantage over standard cables is that the connection is pull-proof and cannot be accidentally disconnected so easily.
The products are compatible with standard IEC plugs and sockets and can be easily integrated into existing environments and server rooms. IEC Lock is particularly in demand when extremely high reliability is required.
