PTX640 / PTE640

The 640kA per phase PTX640 and PTE640 models of the Protector® are designed to safeguard zero tolerance and high priority systems and load equipment in the heaviest industrial environments and applications.

These applications demand only the most effective and durable protection available. Installation of the PTX640/PTE640 assures damaging transients are intercepted before they reach critical loads. Effective in stand-alone applications, or as part of the MEM System Shield® integrated installation-wide protection plan, the PTX640/PTE640 is the answer when downtime is not an option.

Protection Modes:
 All Mode: Line to neutral & line to line (normal mode) and line to earth & neutral to earth (common mode).

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 42dB normal mode, up to 41dB 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 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.
