This relay fastens directly to the contactor — no extra DIN-rail bracket needed, which saves a slot in the panel. The main circuit uses screw-type terminals accepting 2× (0.5... 1.5 mm²) or 2× (0.75... 2.5 mm²) solid or stranded copper. The auxiliary switch is integrated, and there's a dedicated terminal for the 'Tripped' message output — useful for feeding a remote alarm or PLC input without adding a separate aux block.
Ratings and environment
The thermal element compensates for ambient temperature between -40 and +60 °C, so it won't nuisance-trip in a hot panel or cold warehouse. MTTF under high-demand mode is 2,280 years — that's a reliability figure, not a service life, but it tells you the design is solid for continuous-duty applications.
