The time window spans 0.05 to 100 seconds, adjustable with a pot on the face. Thermal current rating is 5 A; switching capacity at 250 V AC is 0.1 A, at 125 V AC 0.2 A, and at 24 V DC 1 A — sized for pilot duty, not motor loads. The 22.5 mm width keeps panel fill tight — you can pack multiple units side by side.","metaTitle":"Siemens 3RP1505-2BW30 SIRIUS Timer Relay, ON/OFF Delay, 24-2","metaDescription":"Siemens 3RP1505-2BW30 SIRIUS timer relay with ON-delay and OFF-delay, adjustable 0.05-100 s.

It supports ON-delay, OFF-delay, and additive ON-delay. Minimum ON period is 35 ms; recovery time between cycles is 150 ms. Non-volatile memory is not present — timing resets on power loss."},{"question":"What supply voltage does 3RP1505-2BW30 accept?","answer":"Universal supply: 24–240 V AC at 50/60 Hz and 24–240 V DC on the same terminals.
