High exposure protection – Compatible with all Current Technology MasterPLAN® facility-wide suppression filter system products

FEATURES

Powerful MPplus units offer selenium-enhanced protection for large ampacity service entrances and service entrances near utility substations or on grids with other large industrial users. Standard MPplus features include:

Selenium-enhanced suppression filter assembly: Selenium cells dramatically increase reliability and extend suppression filter system life by protecting MOVs from damaging overvoltage swells and long duration transients

seamless technology: Proprietary design concept integrates four suppression and filtering components — selenium, polypropylene capacitors, non-linear voltage dependent metal oxide varistors (MOVs) and precise component geometry — for maximum performance and reliability

Diagnostic test point: Allows easy DTS-2 Diagnostic Test Set integration

Fused disconnect: Integral UL listed safety interlocked fused disconnect switch enhances safety, reduces installation cost, improves performance, optimizes reliability and permits system testing without interruption of facility power. Coordinated UL listed 200 KAIC field replaceable Class J fuses provide added convenience and safety

StatusWatch diagnostic monitoring with display event counters: Diagnostic monitoring package includes audible alarm, alarm silence/test, double form “C” dry contacts, status indicator lights and display event counters

Warranty: Ten Year Extended Warranty – includes direct lightning strike coverage

SINGLE PULSE SURGE CURRENT CAPACITY

In compliance with NEMA LS 1-1992, paragraphs 2.2.7, 2.2.9 and 3.9, Current Technology suppression filter systems are single pulse surge current tested in all modes at currents up to 150% of the product design rating by an industry-recognized independent test laboratory. Single pulse surge current capacities of 200,000 amps or less are established by single-unit testing of all components within each mode. Due to present industry test equipment limitations, single pulse surge current capacities over 200,000 amps are established via testing of individual components or sub-assemblies within a mode.

REPETITIVE SURGE CURRENT CAPACITY

Per ANSI/IEEE C62.41-1991 and ANSI/IEEE C62.45-1992, all Current Technology suppression filter systems are repetitive surge current capacity tested in every mode utilizing a 1.2 X 50m sec 20KV open circuit voltage, 8 X 20 m sec 10 KA short circuit current Category C3 bi-wave at one minute internals without suffering either performance degradation or more than 10% deviation of clamping voltage at a specified surge current.

EMI/RFI NOISE REDUCTION VALUES

All Current Technology suppression filter systems EMI-RFI noise rejection or attenuation values are in compliance with test and evaluation procedures outlined in NEMA LS 1-1992, paragraphs 2.2.11 and 3.11.

MAXIMUM CONTINUOUS OPERATING VOLTAGE (MOV)

All Current Technology suppression filter systems maximum continuous operating voltages are in compliance with test and evaluation procedures outlined in NEMA L 1-1992, paragraphs 2.2.6 and 3.6.

TYPICAL VOLTAGE CLAMPING DATA

All Current Technology suppression filter systems clamping voltages are in compliance with test and evaluation procedures outlined in NEMA LS 1-1992, paragraphs 2.210 and 3.10. Values indicate typical clamping voltage data for models with integral fused disconnect (DF).
