Power Protection

The OE Surge Protector J-Coupler provides inline surge protection for devices with a GST connection.

  • Provides 6.5kA protection
  • Dual Active to Neutral and Neutral to Earth protection for protection from differential and common mode surges
  • 20A throughput capacity
  • Thermal fuse to protect against further damage after a power surge
  • Easy to fit J-Coupler provides nearby protection for workstations

The OE Inline Thermal Overload is ideal where overload protection is required locally. Whether because of statutory requirements or where the distribution board is not easily accessible.

Available with 10A, 12A, or 15A protection, the Inline Thermal Overload fulfills statutory requirements in Australia where it is required for 3 or more outlets and in the USA if there are 4 or more outlets.

The Inline Thermal Overload provides convenient protection where space is in short supply and access to the main distribution board is not available.

The Inline Thermal Overload can also provide loadside protection to devices that are connected to higher rated supply side circuits

Inline thermal overloads are designed to open the internal contacts in the event of a current flow in excess of the rated current according to its time/current characteristics. This protects the device from damage, should a surge occur.

A thermo bimetallic strip, which has the advantage of being immune to high inrush currents and line transients, is heated by over current and deflects thereby releasing the latch mechanism. The contacts open even if the reset button is manually held in the closed position. This is known as trip-free mechanism. The contacts open and close with a positive snap action and the tripped state is clearly indicated by the extended projection of the reset button.

Compatible power cords:
• 3 core 1.0mm² cable
• 3 core 1.5mm² cable
• 14AWG cable
• 3 core 2.5mm² cable
All cables can be made to a length of your choice.

 

 

The inline thermal overload is intended to be hardwired into power cord to mains plug, or into starter cables.

30mA residual current breakers (RCD’s)  are a statutory requirement in many countries as a method of providing user protection against electrical shock. If 30mA RCD protection is not provided in the building circuit or at the wall floor socket the it should be provided locally e.g. in the desk electrics.  100mA protection is often provide at the main circuit board but this is not sensitive enough to protect users of electrical equipment.   BS6396 was updated in 2015 to require where a furniture power distribution system is connected to an existing building socket outlet which does not have residual current device (RCD) protection, the furniture socket outlets shall be protected by means of a 30 mA RCD.

Our 40A 30mA RCD’s are as standard type AC (sensitive to AC current only) which comply with UK and  many other country requirements. They have been carefully selected  for quality and reliability and to have certified compliance with IEC61008.  We can also supply to special order AC plus DC current sensitive type A or type B RCD’s to comply with local requirements e.g. in Switzerland and Germany.

Local to the user RCD protection should  be specified at levels lower than any upstream protection such as at a circuit board, so that the local protection is always the first to trip in overload situations.  OE can supply RCD’s built into standard alone units such as our PDU’s (hyperlink to PDU’s page)  with hardwired, Wieland GST, and/or Neutrik power connections or alternatively incorporated into power modules  such as POWER BOX.

RCD protection should not be confused with overload protection via MCB’s,  the latter being to protect circuits/equipment rather than people. Where power is being sourced direct from a floor track then both MCB and RCD protection can be achieved by using an RCBO.

30mA residual current breakers with overload (RCBO’s)  are a convenient method of providing both user protection against electrical shock and overload protection for circuits/equipment, for instance when taking power from a 32A or 64A floor track.

Our 30mA RCBO’s can be specified with  6A, 10A or 16A C curve overload protection all with Type AC (sensitive to AC current only) RCD protection (Type A to special order). They have been carefully selected for quality and reliability and to have certified compliance with IEC61009.

Local to the user RCBO protection should  be specified at levels lower than any upstream protection such as at a circuit board, so that the local protection is always the first to trip in overload situations.  RCBO’s can be built into standalone units such as our PDU’s  with hardwired, Wieland GST, and/or Neutrik power connections or alternatively incorporated into power modules  such as POWER BOX.

OE  mini circuit breaker (MCB) modules are typically used to provide IEC60898 compliant local circuit protection at between 10A and 16A  when connecting direct to a building power circuit which has a higher rating than the power module such as a 32amp floor track.

Our 6Ka breaking capacity MCB’s are as standard C curve trip type (trip at 3-5 x the rated current) and are combined thermal and electromagnetic  design. They have been carefully selected  for quality and reliability and to have certified compliance with IEC60898.

MCB’s can be built into standard alone units such as our PDU’s (hyperlink to PDU’s page)  with hardwired, Wieland GST, and/or Neutrik power connections  or alternatively incorporated into unit such as POWER BOX.

Local MCB protection should  normally be specified at levels lower than any upstream protection such as at a circuit board, so that the local protection is always the first to trip in overload situations.
