What is a Circuit Protection device?

A circuit protection device is a fail-safe device that originates a disruption in an electrical circuit when it recognizes an excess and unsafe power load in a circuit. The main aims of circuit protection are to localise and isolate the situation or fault and avert and minimize any unnecessary power loss.

What Do We Supply?

We have broad selection of circuit protection devices, including:

Circuit breakers

Thermal circuit breakers

Thermal-magnetic circuit breakers

Magnetic circuit breakers

Hydraulic-magnetic circuit breakers

Fuses

LV fuse links

LV fusegear

Schurter 400VDC Connectors

400 VDC Connector According to IEC TS

First connector system in accordance with IEC TS 62735 and IEC TS 63236
Rewirable connectors, appliance inlets and outlets
Hot plug-capable for disconnection under load up to 2.6 kW and up to 105°C operating temperature
Use of bio-based plastics on the appliance side

After launching the first 400 VDC connectors (GP21 and GS21) in accordance with IEC TS 62735, Schurter is now adding models GC21 and GH21/GI21 on the device side - of course IECcompliant. From the network to the device: The Schurter 400 VDC family is the first DC connector solution available worldwide to be complete according to IEC TS.

With the GP21 and GS21 connectors, Schurter launched the world's first DC connector systems standardized according to IEC TS 62735-1 for efficient power distribution in data centers, for power distribution strips and UPS applications back in 2019.

The GH21 and GI21 appliance Inlets are brand new. The GI21 model is designed for pure DC operation, while the GH21 is a hybrid version and can therefore accept both AC and DC current. SCHURTER also offers the rewireable GC21 Connector to match the appliance Inlets. A cord retention system developed from scratch ensures safe operation in everyday use. All three new products are made from a bio-based plastic (Green Plastic).

The Advantages of DC
With a pure DC supply, cost-intensive and failure-prone transformations and conversions, including their components, are completely eliminated. Operational reliability increases with improved efficiency. And climate-friendly technologies that generate direct current are becoming established in energy generation.

IEC TS 62735-1 / IEC TS 63236
Due to its properties, the standards for direct current (2.6 kW) require a more complex connector connection design as DC arcs must be avoided when disconnecting the supply. Another highlight is the extended temperature range of the connector pins from -5 °C to +105 °C.

Matching Cables
Under the designation SPC1, Schurter now also offers suitable, customized DC power cables for all connection options on request.
