SP Series UL recognized Type 1ca Surge Protection Device or class II SPD per IEC61643-11;
For low-voltage power supply system surge protection, especially for point of entry (Category C,D, ANSI/IEEE C62.41) and sub-circuit (Category B, ANSI/IEEE C62.41)protection.
Three phase protection, for TT, IT, TN-S, TN-C system;
In 20kA, Imax 50kA per pole;
PROSURE SP series are defined as high performance surge protection solution for most commercial and industrial environments with critical operations, and UL 1449 Type1ca designed to protect against the harmful effects of transient surges.
These surges are the result of:
– Direct and indirect lightning strikes
– Power company load switching
–Upstream load switching at other facilities
The unit is intended for point-of-entry or sub-board protection and is connected in parallel with the power system. Applied for three phase power supply system.
