ProTec T1SF Multipole Connectivity Configurations

Raycap’s ProTec T1SF Series is based on its patented Phase Gas Discharge Tube (PGDT)
technology, and a new integrated fuse technology. The products ensure safe thermal and
fault-current disconnection on networks with prospective short circuit currents as low as 300 A
and as high as 100,000 A. A coordinated thermal disconnector provides disconnection at low fault
currents (<300 A), extending a continuous fault-tripping characteristic down to 1 A.

Main features:

• Patented PGDT surge protection technology
• Integrated backup fuse
• Leakage-current free product for installation in the pre-metering area
• Shorter connecting cables – low voltage protection level
• Reduced installation space requirements, costs, wiring time and complexity
• Sensitive and reliable state-of-the-art disconnector
• Visual and remote signalization of the device status
• Short circuit current rating up to 100 kA (VDE Certified up to 75kA, 100kA additionally tested by VDE.)

Main use:

• Heavy industry installations
• Transformer stations

Benefits:

• Smallest in-class solution on the market
• Available for TN-S, TT, and TN-C networks eliminate the need for time-consuming wiring of the remote signaling contact and the cross-connection
• No problems when selecting the back-up fuse, as this is completely eliminated
• Back-up fuse and overvoltage protection are monitored and report the tripping status via the remote signaling contact

ProTec T2F Series

The practical 2-in-1 device simplifies planning, installation, and maintenance. For example, the need to dimension a backup fuse is not applicable with the ProTec T2F product series as this is already integrated and matched to its performance parameters.

The new Type 2 arrester has an integrated back-up fuse, a protection level of 1,500 V, a maximum discharge capacity of 40 kA 8/20 μs and a rated discharge current of 20 kA 8/20 μs. In addition to the proven Raycap ProTec T2 technology developed for use in systems with a rated current of up to 315 A without back-up fuse, the T2F Series with integrated backup fuse offers protection independent of installed fuses found in equipment inside large industrial installations.

Main features:

• Integrated back-up fuse
• Maximum discharge capacity of 40 kA (8/20 μs)
• Rated discharge current of 20 kA (8/20 μs)
• Complies with IEC Class II according to IEC 61643-11
• Protection level of 1,500 V
