PTX048 / PTE048

The 48kA per phase PTX048 and PTE048 models of the Protector® are designed to safeguard sensitive and mission critical equipment. The industry's Lowest Measured Limiting Voltage performance on switching generated ring wave transients (by far the most common occurrence in electrical systems) assures maximum equipment protection.

The PTX048/PTE048 models provide the industry's best and most effective combination of high performance features. Effective in stand-alone applications, or as part of the MEM System Shield® integrated installation-wide protection plan, the PTX048/PTE048 is the solution when only the best protection available will do.

Electrical & Performance Specifications

Circuit Design:
 PTX and PTE units feature parallel configured, Threshold Suppression Network™ utilising Transient Control System™ design, circuit encapsulation and Advanced Surge Path Technology™. PTE units also incorporate multi-stage, hybrid Active Tracking Network (ATN®).

Protection Modes:
 Enhanced All Mode (10 modes on three phase star connected units) with dedicated protection components for Modes: normal mode (line to neutral x 3 & line to line x 3) and common mode (line to earth x 3 & neutral to earth).

Supply Frequency:
 50-420Hz (50-60Hz with ATN® option).

Response Time:
 PTX 1 nanosecond, PTE Active Tracking Network < 1 nanosecond.

EMI/RFI Attenuation:
 Up to 39dB normal mode, up to 34dB common mode.

Capacitance:
 2µF per mode (PTE Models).
Note: For applications where earth leakage current may be of concern, please cut enhanced N-E ATN® protection link on PTE models, or utilise PTX models.

Circuit Diagnostics:
 Statscan™ circuit diagnostics, 1 LED indicator per phase, normally on. Remote alarm via Form C, N/O and Diagnostics:N/C volt-free relay contacts, with internal terminal connections (0.5mm² to 1.0mm²). Optional S.M.A.R.T. diagnostics with surge counter & event history recording.

‡ Measured Limiting (Let-Through) Voltage Test Environment:
Test waveforms as described in ANSI/IEEE C62.41- 1991 (A1 Ring Wave - 100Khz, 2,000V, 67A, B3/C1 Combination Waveform 6,000V 1.2/50µs, 3,000A 8/20µs, C3 Combination Waveform - 20,000V 1.2/50µs, 10,000A 8/20µs) All modes tested dynamic except N-E, positive polarity. All voltages are peak (+/-10%), oscilloscope time-base 1ms. 180° phase angle voltages measured from the zero crossing, 90° phase angle voltages are measured from the positive peak of the AC sine wave to the positive peak of the surge. All tests performed with a 152.4mm (6-inch) lead length, simulating actual installation conditions. Options offered may result in performance variance.
