It is a DC 24V-controlled unit in the S00 frame size, rated for a motor current of 0.3 A at AC-3 duty (0.09 kW at 400 V). The adjustable overload release covers 0.28 to 0.4 A, and the unit can interrupt faults up to 50 kA at 400 V. ## Safety ratings in context — Cat. 4 and SIL 3 Category 4 per EN 954-1 means the load feeder is fault-tolerant to a single failure and can detect most accumulations of faults — it is the highest category under the older standard, typically used for safety functions like emergency stop or guard door monitoring where a single fault must not lead to loss of the safety function. SIL 3 per IEC 61508 is the corresponding performance level under the functional safety standard, covering applications where the tolerable risk is very low. For a direct starter, this means the internal monitoring circuits (the load feeder includes cascading capability) can detect a welded contactor or a stuck overload relay and signal the fault to the safety controller. ## Where it fits — panel integration and environment It occupies the S00 footprint (90 mm wide, 211 mm tall, 113 mm deep) and snaps onto a 35 mm DIN rail — standard for European-style panels. The main circuit connects via screw-type terminals, which is the traditional preference for maintenance electricians who want to torque-check connections.","metaTitle":"Siemens 3RA7141-0EA17-0AB4 SIRIUS Safety Load Feeder, DC 24V","metaDescription":"Siemens 3RA7141-0EA17-0AB4 SIRIUS safety load feeder, DC 24V, S00 size, 0.3A AC-3 motor current, SIL 3 / Cat. 4.
