Spa Panel Package · 40A 2-Pole GFCI · 4-Space/8-Circuit 125A Main Lug Outdoor NEMA 3R · Siemens W0408ML1125-40
SKU: W0408ML1125-40
Outdoor spa panel package with factory-installed 40A 2-pole GFCI breaker in a 125A main lug, 4-space/8-circuit loadcentre. Commonly used for 120/240V single-phase hot tub and spa installations where an outdoor-rated disconnect and GFCI solution is required.
What this product is for
This Siemens spa panel package is used to supply and protect outdoor hot tubs, spas, and similar equipment requiring a 40A 2-pole GFCI breaker. It combines a 125A main lug loadcentre with a factory-installed GFCI breaker in one outdoor-rated enclosure.
Use for
Use for 120/240V AC, single-phase, 3-wire spa and hot tub installations, pool-related equipment where permitted by design, and outdoor branch-circuit distribution needing a NEMA 3R enclosure. The 4-space/8-circuit interior can also provide room for additional accessory circuits where the installation design requires them.
Avoid for
Avoid for indoor-only locations, corrosive environments unless additional protection is specified, or applications that require a different breaker size, enclosure type, or service-entrance configuration. Do not assume suitability for every spa pack replacement without confirming voltage, load, breaker type, and local code requirements.
Best for
Best for electricians replacing or installing an outdoor spa disconnect with integrated GFCI protection, especially where a compact weather-resistant panel with extra circuit capacity is preferred.
Installed in
Typically installed outdoors near residential hot tubs and spas, on exterior walls, service areas, or equipment pads. Enclosure dimensions are approximately 12.25 in H x 6 in W x 4.25 in D (312 x 155 x 108 mm).
Why this product exists
This package simplifies spa installations by combining the disconnecting means and required GFCI protection in one assembly. For many hot tub applications, this reduces field assembly time compared with sourcing a separate outdoor loadcentre and breaker.
Typical buying guidance: a 40A spa panel is commonly selected for hot tubs whose manufacturer calls for a 40A GFCI-protected feeder or branch circuit. Actual suitability depends on the spa nameplate, heater load, pump load, conductor sizing, installation conditions, and local electrical code.
Compared with similar products
Compared with a bare outdoor loadcentre, this package includes the factory-matched 40A 2-pole GFCI breaker. Compared with larger spa packs, it is intended for installations that specifically call for 40A protection rather than 50A or 60A. The 125A bus and 4-space/8-circuit layout also provide more flexibility than a simple disconnect-only enclosure.
