LS Electric Metasol MC Timer, Latch and Delay Release Units

LS Electric Metasol MC Timer, Latch and Delay Release Units

LS Electric Metasol contactor add-on units: UN pneumatic timer blocks, UT electronic timers, ML/AL mechanical latch units and AD delay release (undervoltage ride-through) units.

Key features

  • UN pneumatic timer blocks, on-delay (N) or off-delay (F), 1NO+1NC, ranges 0.1-3 s, 0.1-30 s, 10-180 s
  • UT electronic head-on timers, on- or off-delay, 1-30 s, AC/DC 24-48 V or AC 110-220 V
  • ML/AL mechanical latch units keep the contactor closed without coil power (DC operation max. 150 ops/h)
  • AD delay release units hold the contactor 1-7 s through momentary power failures (MC with DC coil)
  • Fit Metasol MC contactors 6a to 800a and MR auxiliary relays as listed
