ProTec ZPN T1H Series
Raycap ProTec ZPN T1H is a compact IEC Class I+II / EN Type 1+2 Surge Protection Device (SPD) mounted on a 40 mm busbar system. Thanks to its slim design, the SPD + terminal bar + fuse holder fit together into the width previously occupied by only the surge arrester.
ProTec ZPN T1H are compact IEC Class I+II / EN Type 1+2 surge protection devices designed for mounting on a 40 mm busbar system. They are universally applicable in all main distribution cabinets using 40 mm busbars.
A distinguishing feature of the series is its space efficiency. The slim design of the ZPN leaves room within the panel for a functional terminal bar (ProAcc ZP-TB) and a fuse holder (ProAcc ZP-FH). The terminal bar enables the incoming power connection and transfers the supply to the 40 mm busbar system.
The gain here is that the total width of the product + terminal bar equals the space previously occupied by only the surge arrester. This means you fit the same protection and two additional functions into the same space. In full panels or new panel designs, this directly translates to module savings.
The product uses leakage current-free technology and offers high load capacity in a small installation volume—a continuous current rating of 101 A. Installation is fast thanks to the pluggable connection to the busbar. F versions come with an integrated fuse. The top surface of the product is easy to mark, simplifying identification and labeling within the panel.
