Dead-front safety shutter prohibts user access to live contacts. Standard locking feature allows device to be locked together while connected or safely locked and tagged out when disconnected. Jumpers included for 600 and 750 VDC devices.

Benefits

Enhanced User Safety

Signature MELTRIC safety features protect users from electrical hazards:

  • Dead-front safety shutter prevents user access to live parts.
  • Padlockable pawl enables easy locking in the connected or disconnected mode.
  • Lockout hole in the pawl prevents accidental disconnection under load.
  • Jumpers are provided on 600 VDC and 750 VDC models; they're a safety precaution to split the arc in case of accidental disconnection under load.

Ultra-Reliable Connections

  • High-quality silver-nickel contacts provide reliable electrical conductivity 24/7. MELTRIC contacts don’t weld together from high heat or suffer conductivity loss from oxidation the way brass and copper contacts do. 

  • Coil springs push against silver-nickel butt contacts, providing tight, consistent force when the contacts meet. This results in lower contact resistance, improved electrical performance, less heat and oxidization that can damage the contacts.

  • MELTRIC contacts are offset, providing a self-cleaning wiping action as they close. This removes dirt and deposits from the contact surface, resulting in improved electrical conductivity.

Watertight Protection

MELTRIC DSDC plugs and receptacles are designed to protect your electrical connections from water and moisture. 

Environmental ratings range from Type 3R, IP54/IP55** to Type 4X (optional), depending upon model and casing.
