MS220KA-AC-DC24V-2U - PTC Thermistor Relay - T228114

  • T228114
  • Additional information Black painted aluminum sheet
  • Product Type IP54 motor, IP20 electronics
  • Supply voltage AC/DC 24 V
  • Execution Motor IP44, electronics IP20 / depending on mounting and position
  • Certificate UL/CSA, ATEX, EU / UKCA-Deklaracja Zgodności, UKCA
  • Output function Outputs/Relays
  • Measured value Electronic protection against reverse polarity and locked rotor.

PTC-relay for the application as a protection device against inadmissible heating up at electrical equipment in areas with explosive gases (zones 1 and 2) and areas with combustible dust (21 and 22), e.g. for direct temperature-monitoring of explosion-proof motors EEx e and EEx d. Vertically arranged terminals. Each terminal remains accessible even if all others are already occupied.
