The Littelfuse SSAC KRD94115SB is a retriggerable single shot timer for 120 V AC, with isolated SPDT relay contacts rated 10 A resistive at 125 V AC. Its delay is fixed at 15 seconds, set at the factory.
Upon application of input voltage the output energizes and the delay starts; at the end of it the load de-energizes. Closing or re-closing the initiate switch resets the delay and restarts timing with the output still energized (retriggerable).
Output: 1C SPDT relay, 10 A resistive at 125 V AC; 5 A resistive at 230 V AC and 28 V DC; 1/4 hp at 125 V AC (at 40 °C), output initially energized. Repeat accuracy: ±0.5% or 20 ms, whichever is greater. Setting accuracy: Factory calibration ±5%; ±5% over temperature and voltage. Reset time: 150 ms. Supply tolerance: -20% / +10% of nominal; 50/60 Hz. Power: 2 VA. Life: 10,000,000 operations mechanical, 100,000 electrical.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from -20 to +60 °C and stores from -40 to +85 °C.
