- 1 NO + 1 NC auxiliary contacts for fault signalling
- Direct plug-in mounting under LC1D09-LC1D38 contactors or on DIN rail
- Multi-standard certified (IEC/UL/CSA/CCC/EAC/ATEX/Marine), Green Premium
- Adjustable 9 to 13A thermal setting range with Class 10A trip characteristic
Technical Specifications
Version & Model Difference
The LRD16C is the 9-13A member of the TeSys Deca (TeSys LRD) thermal overload relay range, which spans multiple setting bands (e.g. LRD06 0.1-0.16A, LRD21 12-18A, LRD32 23-32A). All share the same Class 10A differential bimetallic design and LC1D plug-in mounting, differing only in current setting range.
