Protection and Connection SlimLine XR Switch Disconnector Fuse 63-630 A Power and productivity for a better world™

Apparatus overview Technical Data Ordering tables Dimensional drawings

Easy and reliable The fuse is a superior short circuit protection element regarding the maximum allowed cut-off current (peak let through current) and energy value. This is more important the higher the voltage and prospective fault levels get. The SlimLine switch disconnector fuse fulfil the highest requirements for modern switch fuses with a total safety concept. The switch fuses are tested according to the EN 60947-3 standard with more stringent requirements for isolation, making, performance and safety.The fuse rails are tested according to IEC 60269-2-1. The melting curves and current limiting...

The latest within optimal operation and design The SlimLine XR fulfils all increasing demands in the industry for safe energy distribution. Installation of the SlimLine XR is even easier and more time saving than ever before. The increased space in the cable termination area will allow better access for the cable installation. Motor operation SlimLine XR offers an integrated motor (as option) for remote or local operation. The motor operation unit is 100% integrated inside the SlimLine XR. The front operated ON / OFF buttons are shrouded by a transparent cover with padlocking facility. Electronic...

Apparatus overview Installation and operation 3 Plug-in contacts - Fast, easy and safe Years of experience and development are put into the plug-in contacts used in the XR. The basis for the technology is that the current floats in small spots within the apparent contact point. These spots are named “effective contact areas”. A spring loaded contact achieves a high contact force. This again leads to a high “effective contact area”. Installation Slide the SlimLine apparatus into the panel until the guide pins fit into the rear profiles and the contact fingers are c ­ onnected to the busbars. The...

Apparatus overview Plug in/out at live busbars and double handle Plug in/out at live busbars The SlimLine apparatus can be removed/replaced in a switchboard with live busbars according to IEC EN 61439 8.5.2. An integrated interlock device at the side of the apparatus will prevent any possibility to plug out/plug in the apparatus at live busbars as long as the XR apparatus is switched to ON position. We recommend the following procedure when removing/replacing SlimLine XR in a switchboard with live busbars: 1. The replacement is carried out by a skilled or instructed person 2. The switch fuse...

Apparatus overview Replacement of the NH fuses in the XR How to replace NH fuses in a XR 00 that is placed between other XR apparatus in ON position 1. Switch OFF the XR where the NH fuses shall be repalced and open the frontcover. 2. The operating handles of the XR’s placed above and below can be released by use of a screwdriver and moved to ­ ark-position with the XR’s still in ON position. p 3. With the operating handles above and below in parkposition, there is easy access to the L1 fuse in the XR in the middle. 4. By use of a NH replacement tool, the NH fuses in the XR 00 in the middle can...
