Description
The frame is assembled from thin-walled perforated galvanized profiles of 50 × 25 mm with a perforation pitch of 25 mm, and the front doors are made of 1.5 mm painted sheet (RAL 7032). The board height is 1 850 mm, width 600–2 500 mm, depth 250 mm for busbars up to 1 250 A and 400 mm above that current. All busbars are copper, the main phase busbars are arranged vertically with a centre distance of 185 mm, and strip-type devices are mounted directly on them. The main device can be an in-line switch-disconnector up to 1 250 A (RWS 1250), its fused version (ARS), a rotary switch up to 2 000 A, an MCCB for 630–1 600 A or an ACB for 1 000–2 000 A, and instead of one device of sizes 1–3 two of size 00 can be fitted. For the RTL the rated voltage Un is 230/400 V, Ui 690 V, Uimp 8 kV (1.2/50 µs), outgoing feeder current 160, 250, 400 or 630 A, 1 s current 50 kA, peak 105 kA. The protection rating is IP30 at the front, IP20 with OEZ and Efen devices and IP40 for the other compartments. Compliance with PN-EN 60439 and PN-EN 60529, certificate No. 1025/NBR/2010. Operating conditions are free of dust and aggressive gases, from −25 to +40 °C.
How to choose
The RTL has small dimensions and permits current and energy measurement in outgoing circuits, cable connection without crimping lugs, and operation in TN-S, TN-C, TN-C-S, TT and IT networks. The RTLs additionally has automatic transfer switching, cable entry from below and above, the ZUMiS remote monitoring system and fuse-link blow monitoring.
