Blue Sea Systems AC Rotary Source Selector Switch, 240V AC, 65A, 3-Pole, Single Output

Overview

This Blue Sea Systems AC rotary source selector switch is a panel-mount AC power source selector for routing one 120/240V AC source to a single load circuit on a boat. It is a 3-pole, 65A rotary switch with an OFF position, built for AC systems where the source selector is separate from the circuit protection.

The switch is used in shore power, generator, and inverter-style AC distribution layouts where the operator needs one clear control point for selecting the active source. The 3-pole layout switches both AC hot lines and neutral, which is important in split-phase 120/240V marine AC systems.

The range covers 2-source and 3-source configurations. Both versions are rated for 240V AC nominal service, 600V AC maximum voltage, and panel mounting in material up to 0.16 in thick.

Key features

• 3-pole AC rotary switching for both hot lines and neutral in 120/240V AC source-selection layouts.
• 65A maximum amperage rating for higher-capacity AC distribution panels.
• Single load circuit output, with source count based on the selected variant.
• OFF position included, so the AC load circuit can be disconnected from the available sources at the selector.
• Mounts in panels up to 0.16 in, or 4.00 mm, thick.
• 600V AC maximum voltage rating and 240V AC nominal rating.
• UL listed for use in properly installed AC electrical systems.
• Suited to panels where circuit protection is already handled elsewhere in the AC distribution system.

Variants

This product is offered in two source-selection configurations for different AC layouts.

The source count and switch position count change between variants. The 3-pole construction, 65A rating, single load circuit output, 240V AC nominal rating, 600V AC maximum rating, and 0.16 in maximum panel thickness remain consistent across both versions.

• 9019: Source Selection 2 Sources. This version has 2 positions plus OFF and is commonly used where one load circuit is selected between two AC sources, such as shore power and generator.
• 9077: Source Selection 3 Sources. This version has 3 positions plus OFF for systems that need one additional selectable AC source while still feeding a single load circuit.

Installation and setup

This switch is meant for panel mounting in an AC distribution layout. It belongs in a dry, serviceable electrical panel location where the operator can clearly see and use the selector, and where wiring can be secured against vibration and strain.

Because the selector does not replace overcurrent protection, the AC sources and load circuit should be protected by the correct breakers or fuses elsewhere in the system. Installation should follow marine AC wiring practices, including proper conductor sizing, terminal torque, source labeling, and verification that only one AC source can feed the load circuit through the selector at a time.

Compatibility and fit

This range is a match for boats using 120/240V AC source selection with one output load circuit. It is relevant for cruisers, sportfishing boats, and larger vessels that manage shore power and onboard AC generation from a dedicated electrical panel.

The main fit decision is the number of AC sources that need to be selected. The 2-source version keeps the panel simpler when only two inputs are present, while the 3-source version supports an added AC source in the same basic switch family.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
