Thermal overload relays

Thermal overload relays

Series MT3
Overload protection on all three phases

  • Operating current range: 1~630A
  • Rated voltage: 690V
  • Functions: Trip, Reset A/H

  • Easily adjust the current and visually recognize the operating status
  • Auto/manual reset mode
  • The Thermal type (bimetallic element) for thermal overload relay ≤ 225A is manufactured in accordance with UK standards
