Schurter has added its V-Lock cord retention system to a re-wireable IEC C13 mains appliance inlet connector.

Called 4783, it is available in black, white and grey for differentiation – for example when used for three-phase systems, said the company, adding: “Reconnectable appliance sockets are particularly suitable for small series builds. With these inlets you are free to choose the cable length and country-specific plugs.”

All three colours are available in two sizes, one for 8.5mm cables (3 x 0.75mm2 18AWG 0.82mm2) and one for 10mm (3 x 1.5mm2 14AWG 2.08mm2)

4783 has approvals for the European, Chinese and North American markets, including certification to the new UL 60320 standard.

Ratings are

• IEC 10A 250Vac 50Hz
• UL/CSA 15A 250Vac 60 Hz
• >1.5kVac between L-N
• >1.5kVac between L/N-PE (1 min/50 Hz)
• -25°C to 70°C
• >200N pull-out force

On power cord retention, the company said: “The loss of the power supply may have serious consequences for analytical, diagnostic or laboratory equipment in medical technology, mobile measuring instruments, professional audio and video equipment or devices in the food industry. Particularly in the case of electrical appliances that are moved during operation, there is a risk that the mains cable may be unintentionally disconnected from the appliance. Cord retention safety devices can prevent this.

“In the case of V-Lock, the socket with a plug clicks into the opening in the device plug provided for this purpose and thus prevents unintentional disconnection of the mains cable,” it said. “The advantage of this system is that there is no need to adapt and assemble cable plug-specific bracket systems or retaining brackets.”
