MS4620F1203/B

Fast-Acting, 2-Pos Actuator - 175 lb-in

  • Product Info
  • Literature

Overview

Honeywell's Fast-acting, two-position actuator with 175 lb-in., 20 Nm spring return and 230 Vac actuator accepts two-position control with an integral junction box and accepts an on/off signal from a single-pole, single-throw controller. Reliability operates in smoke control systems requiring UL555S ratings up to 350F.

Features

  • 175 lb-in. (20 Nm) minimum driving torque at 350F (176C)
  • Integral stainless steel spring return ensures return torque level
  • Reversible mounting allows clockwise (cw) or counterclockwise (ccw) spring rotation
  • Fifteen-second spring return timing
  • No special cycing required and no audible noise during long-term holding
  • Models available with integral high temperature (350 F) SPST position-indicating switches (<7 degrees, >85 degrees)
  • Ninety-five degree angle of rotation for tight damper closure
  • Actuator holds rated torque at reduced power level and die-case aluminum housing design allows flush mounting to damper
