Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0400041003F as obsolete. No direct factory orders are accepted; the part is sourced through independent distribution against an RFQ, with availability and pricing confirmed at quote time. No official successor or cross-reference is recorded from the manufacturer. A functionally equivalent planetary gearbox with the same 40 mm frame size, 4:1 ratio, and 15 N.m continuous torque rating would need to be selected from current production lines.
4:1 planetary reduction with 15 N.m continuous torque
This is a straight-tooth planetary gearbox with a 4:1 reduction ratio, delivering 15 N.m continuous output torque at 100 rpm and 30 °C ambient. Maximum output torque reaches 24 N.m under the same conditions, providing a 1.6× overload margin for transient loads. The 30 arcmin maximum torsional backlash places this in a moderate-precision class — suitable for positioning applications where repeatability within half a degree is acceptable, but not for zero-backlash servo axes. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no periodic oil changes are needed. Axial and radial force limits are 200 N for 10,000-hour life, derating to 160 N for the full 30,000-hour service interval.
94% efficiency and 55 dB noise floor
Efficiency is listed at 94%, meaning 6% of input power is lost as heat through gear mesh friction and bearing drag. At the continuous 15 N.m output, this translates to roughly 6 W of thermal dissipation — the black anodized aluminium housing (40 mm diameter) handles this without forced cooling in most panel environments. Noise level is 55 dB at 1 m under no-load conditions — roughly the sound of a quiet office. In a loaded installation, expect a few dB higher from gear mesh harmonics. The straight-tooth geometry is inherently noisier than helical, so this is a design trade-off for lower cost and zero axial thrust.
Shaft output IP54 — sealed against splashes, not submersion
The shaft output carries an IP54 rating, meaning the seal at the output shaft resists dust ingress and splashing water from any direction. The housing itself is black anodized aluminium, and the shaft is C45 carbon steel — both materials are corrosion-resistant in dry indoor environments but may need additional protection in washdown or outdoor duty. The lubricant is rated for this full range, so no cold-start warm-up is required down to -25 °C.
