Altran Magnetics ASEV50 High-Voltage DC Contactors

Altran Magnetics ASEV50 High-Voltage DC Contactors are 50A+ and 900VDC DC contactors with an inert gas-filled arc chamber for high-voltage switching. The Altran Magnetics ASEV50 features a small, low-profile design with low noise while carrying or switching loads. The series is safe for use in explosive environments, with no arc leakage due to its hermetically sealed design. The ASEV50 is mountable in any orientation without compromising performance.

Features

  • High current carry and high voltage - inert gas-filled arc chamber suitable for high-voltage switching
  • Compact structure and low noise - small, low-profile designs with low noise while carrying or switching loads
  • Safe for explosive environments - no arc leakage due to a hermetically sealed design
  • High-reliability design - hermetic sealing creates a stable environment for high-voltage switching
