The relay output is rated for a thermal current (Ith) of 5 A, with switching capacities of 1 A at 24 V DC, 0.2 A at 125 V DC, and 0.1 A at 250 V DC. The minimum ON period is 35 ms, and recovery time between cycles is 250 ms. Housed in a 22.5 mm wide enclosure with a depth of 90 mm and height of 100 mm, it mounts via screw and snap-on onto 35 mm DIN rail in any position. This narrow footprint fits tightly packed control panels where space per function is at a premium. Tightening torque is 0.6 to 0.8 N·m. The relay supports additive ON-delay, pulse-delayed switching, and pulse-shaping, but does not retain time settings non-volatilely — power loss resets the timing cycle.","metaTitle":"Siemens 3RP2505-1RW30 SIRIUS Time Relay, ON-delay, 0.05 s to","metaDescription":"Siemens 3RP2505-1RW30 SIRIUS time relay, ON-delay, 24-240 V AC/DC, adjustable 0.05 s to 100 h, 5 A thermal, 22.5 mm wide.
