• First IEC connector system on the market for 400 VDC according to TS 62735-1 (2.6 kW)
• Designed for PDU and UPS in Data Center
• Various terminal options
• Safe disconnect under load
With the GP21 plug connector and the GS21 socket-outlet, SCHURTER launches the world's first UL approved IEC TS 62735-1 standardized DC connector system designed to enable efficient DC power distribution in data centre power distribution strips and UPS.
With a complete DC power supply architecture, from source to load, the cost-intensive and failure-prone transformations and conversions, including their components, are completely eliminated. Operational reliability increases with improved efficiency.
In the digital age, vast quantities of DC-powered devices are in use: consumer electronics, industrial IT, communications technology, and electric vehicles to name a few. New technologies are beginning to emerge to enable direct current at the source of supply, which in turn is driving the establishment of standards.
Direct current improves the quality of the power being supplied. Problems with harmonics and harmonic distortions are eliminated. Phase compensation is also not necessary. Furthermore, coupling synchronization to different sources and networks is no longer necessary.
IEC TS 62735-1
The new standard for DC power distribution up to 2.6 kW requires a more complex design. The Connector system must be designed considering the potential for arcing associated with disconnecting the DC power supply. The permissible temperature range of the connector pins is -5 °C to +105 °C. An additional interlock for arc protection, while hot plugging, is not required for the version up to 2.6 kW.
Plug GP21 / Socket-Outlet GS21
The re-connectable SCHURTER GP21 plug accommodates a cable cross-section of between 0.75mm²/18 AWG and 1.5 mm²/16 AWG. The corresponding socket-outlet GS21 is designed for front panel thicknesses of 1.5 mm or 2.0 mm. Quick Connect 6.3 x 0.8 mm or PCB terminals are available for the connection.
Outlook
The reduction of steps to convert power resulting in less power loss, clearly speaks to the need for the use of DC power supply in data centres.
IEC TS 62735-2 is in process for the standardization of a higher DC power requirement of up to 5.2 kW. The appropriate interconnect with the necessary safety interlock (cold switch) are currently being developed.
To increase operational safety, SCHURTER will also be equipping its 2.6 kW plug with a cord retaining system. Appliance-side DC components, such as inlets and cord connectors, are being standardized in IEC TS 63236. This standard is currently in the draft phase and is expected to be published by the IEC in 2021.

The IEC appliance filter series 5120 and 5123 are now as standard equipped with the V-Lock cord retention feature. With the V-Lock system, the power connector is equipped with a latch that interlocks with a special notch in the inlet and thus reliably prevents the cord from being pulled out.

• Compact Construction
• Prewired Blocks with 2, 4 or 6 outlets
• V-Lock Cord Retention
• Color Coding in Black, Grey and White
With the series 4751 SCHURTER is introducing a new ganged IEC block style outlet, which provides an efficient solution for power distribution units and uninterruptible power supply units.
For the safe operation of systems in data centers, telecommunication or PA-systems, standardized, high grade and automated mounting processes are a necessity.
The blocks include 2, 4 or 6 IEC outlets type F, and are prewired and terminated with Quick Connectors 6.3 x 0.8 mm. An asymmetric panel cur-out allows for an efficient mounting process, ensuring proper outlet assembly. The series is certified by VDE and CCC for 10 A at 250 VAC and by UL for 15 A at 250 VAC.
For better optical distinction, especially useful in a multi-phase system, the individual blocks can be produced in black, grey and white.
To prevent an inadvertent disconnection of power, the new blocks are compatible with the V-Lock cord retaining system. The snap-in mounting is standard for a 1.5 mm panel thickness.
BC320: Blind Cover for Outlets of Type F / Type J
In order to prevent overload of modern power distribution strips with multiple IEC outlets, individual outlets can be protected by means of tamper resistant blind covers. These protective caps are mounted onto the outlets in the power distribution strip just like a plug. For safety reasons, the optionally available protective caps cannot be removed without the special tool/key.

• High IP protection up to IP67
• Recessed rocker switch prevents accidental switch-off
• Versatile mounting options
• V-Lock cord retention
With the DG12, Schurter launches its most versatile power entry module with IEC inlet, integrated circuit breaker and a mains filter – with optional IP protection. Thanks to its extremely compact dimensions and a wide range of mounting options, it consolidates discrete power components into one space-saving unit suitable for a variety of applications.
The new DG12 filter series from SCHURTER combines an IEC inlet with a TA35 miniature circuit breaker and a mains filter – with optional IP protection. The DG12 is available for almost any mounting variant with snap or screw mounting. In addition, the flange mount version is available in either vertical or horizontal arrangement.
Thermal Circuit Breaker
The DG12 has an integrated TA35 bi-pole circuit breaker. It offers the function of a device switch as well as thermal overcurrent protection. The overcurrent protection is available with a bi-metal switching package on one or two poles and with rated currents from 0.05 A to 15 A. The rocker switch is available illuminated or non-illuminated, as well as in a variety of colours and markings.
IP Protection
In addition to the standard versions with IP40 protection, the DG12 is available in a version with IP67 seal protection to the panel and circuit breaker. The use of the DG12 in harsh environments with dust or splashing water is ensured with a cover for the circuit breaker, as well as sealing gasket and four sealing screws for fastening the flange.
Wide Range of Applications
The DG12 series is certified for currents up to 10 A/250 VAC according to IEC standard and 15 A/125/250 VAC UL/CSA standard. The filter series is available in standard or medical versions and for protection class I and II. For applications that require a particularly high immunity to interference, versions with high inductance filters are available. Such applications for example are IT or telecom systems according to IEC 90650, and medical devices according to IEC 60601-1. The series is compatible with V-Lock cord retention connection cables.
