SCT5xxx | Ring-type current transformer for differential current 0...2 A, type B/B+ (all-current sensitive), ISO62020-1 conform · 0 次阅读

Mounting instructions, mounting options

• Make sure that the working environment is safe during assembly, maintenance and installation work. Interrupt the power supply of the primary conductor and secure against being switched on again inadvertently.
• Install the current transformer on the primary conductor.
• To do this, feed the primary conductor through the opening of the current transformer housing
• The device can be fastened directly to the primary conductor or alternatively to a mounting plate. Use the fastening materials included in the scope of delivery for this.

Fig.18: Mounting SCT5xxx

• Fastening the base plate with screws in the four holes
• Free suspension on the cable with the help of cable ties through the hooks on the back for attachment
• All current-carrying conductors/lines must be routed together through the measuring current transformer, see Fig, "Use in single-phase and 3- and 4-pin three-phase systems".
• An existing protective conductor must not be routed through the transformer
• Bending of the primary conductors may only take place from the specified minimum distance. The bending radii specified by the manufacturers must be observed.

Fig.19: Calculation bending primary conductor: *distance to 90° angle = 2x outer diameter

• The conductors are to be centered in the measuring transformer
