The Siemens 3RU2926-3AA01-ZX95 is a stand-alone assembly support for SIRIUS Size S0 overload relays — specifically the 3RU21, 3RB30, 3RB31, and 3RR2 families.
Depth is 87 mm — about 10 mm shallower than the 3RT2024 contactor it pairs with, which helps when gland-plate clearance is tight.
Width is 45 mm, depth is 87 mm, height is 97 mm — the standard S0 footprint.
Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Not directly — the 3RV1011-1HA10 is a motor-protective circuit breaker (S00 frame, 45 mm wide, 75 mm deep), while this is a mounting support for an S0 overload relay. Both share the 45 mm width and snap onto 35 mm DIN rail, but the S0 frame is taller (97 mm vs 90 mm) and deeper (87 mm vs 75 mm), so panel layout and wiring clearance need checking.
