Design and Performance
Differential Protection for Higher-Power Motor Starters
As a differential thermal overload relay compensated with phase failure sensitivity, the LRD3353 protects larger three-phase motor circuits against overload and phase failure conditions when paired with LC1D80 or LC1D95 contactors.
High Insulation Voltage for Demanding Power Circuits
Rated for 1000 V insulation per IEC 60947-4-1, the LRD3353 supports higher-voltage industrial power distribution systems, extending overload protection to more demanding applications than lower-voltage relay variants.
Manual or Automatic Reset with Trip Indicator
A compensated relay design featuring a relay trip indicator, alongside selectable manual or automatic reset, gives operators clear fault status visibility and flexible control over restart behavior after an overload event.
Heavy-Gauge Terminal Capacity for High-Current Wiring
Power circuit screw clamp terminals accept conductors from 4 to 35 mm², accommodating the heavier cable gauges typical of the higher current range associated with LC1D80/LC1D95 motor starter assemblies.
Reliable, Proven TeSys Deca Platform
Part of the broader TeSys Deca thermal overload relay range — very reliable and covering motor ratings up to 150 A — the LRD3353 mounts directly onto same-size-ratio LC1D contactors with screw clamp connectors to form a compact, coordinated starter.
