Functional Features:

  • Thermal overload protection — bimetallic strip with adjustable current range
  • Magnetic short-circuit protection — solenoid trip for high fault currents
  • Phase-loss / imbalance protection — trips on single-phasing
  • Trip indicator — red flag shows tripped state
  • Lockable handle — padlock provision for LOTO (Lockout/Tagout)

Applicable Industries:
HVAC, Pumps, Compressors, Conveyors, Machine Tools, Food Processing, Water Treatment

Installation Requirements:

  • Mount on DIN rail EN 60715 (35 mm)
  • Connect motor cables to terminals L1/L2/L3 (top), T1/T2/T3 (bottom)
  • Set overload current using the rotary dial to match motor FLA (Full Load Amps)
  • Ensure adequate ventilation — derate if ambient > 40°C

Usage Notes:

  • Do not use as a general-purpose circuit breaker — this is specifically for motor protection
  • Set overload range to 100–115% of motor rated current
  • Test trip function quarterly
