What the housing gives the panel
The 3RP1533-2AQ30: It accepts solid or stranded conductors 24...16 AWG at the terminals, so the same ferrules and ring-lugs already on the panel wiring land directly without re-tipping.
Coil supply and what the time window covers
The adjustable time range is 5...100 s on a single scale (initial 0.85, full-scale 1.1), with recovery time of 150 ms and a minimum ON period of 35 ms — the timing figures a process loop needs when sizing dropout sequencing or compressor re-start inhibition.
Contact ratings and how to read them
One delayed switching contact is provided; the output is non-volatile (timing state is not retained through a power loss), which matters for any sequence that re-starts from zero on restoration rather than picking up where it left off.
Environment, insulation, and panel-side fit
Basic insulation with pollution degree 3 supports installation in a standard industrial panel without clearance upgrades, and any mounting position is permitted, which simplifies retrofit into cabinets where the original layout dictated orientation.
Sourcing posture
Lifecycle stage is recorded as current; no official LTB or successor is on the record for this order code.
