S0 size, 45 mm wide, 109 mm tall, 85 mm deep — it clips directly onto the contactor (contactor mounting fastening method), so no extra DIN rail footprint. Spring-loaded terminals for the main circuit accept up to 1x 10 mm² stranded or 2x 1.5 mm² solid; screwdriver shaft 5 to 6 mm, Pozidriv PZ 2 tip. The integrated auxiliary switch handles signaling at 24 V (2 A), 120 V (4 A), or 230 V (3 A) — enough to drive a PLC input or a remote lamp. Mount it in any position; vibration rated to 15g / 11 ms shock, and 1-6 Hz, 15 mm / 6-500 Hz, 20 m/s². Class 10E is the standard trip class for standard induction motors; it allows a 10-second overload at 7.2× FLC before tripping, which covers most start profiles without nuisance trips. The 25 A thermal current is the continuous rating; the relay is sized for the motor FLA, not the contactor frame. The note \"for message 'tripped'\" means the auxiliary contact position 97/98 changes state when the relay trips — use that for a remote alarm or PLC input.","metaTitle":"Siemens 3RB3026-1QE0 SIRIUS Solid-State Overload Relay, Clas","metaDescription":"Siemens 3RB3026-1QE0 SIRIUS solid-state overload relay, Class 10E, 25 A thermal current, 690 V rated.
