Hubbell HBL100AITSSB 25kVA 60H Isolation Transformer W/Boost — Product description

Engineered for Unmatched Marine Power Reliability

In the demanding world of marine applications, where fluctuating shore power can threaten sensitive electronics and accelerate corrosion, the Hubbell HBL100AITSSB stands out as a robust 25kVA, 60Hz isolation transformer equipped with ISO-Boost technology. Designed specifically by shore power specialists, it delivers cleaner, more stable electricity to boats and yachts, shielding against electrical noise, voltage irregularities, and ground faults that plague marinas worldwide.

What sets this transformer apart is its fully encapsulated core and coil, sealed with electrical-grade silica and resin compounds. This innovative design locks out moisture, air, and contaminants, ensuring longevity even in harsh saltwater environments. The UL Type 3R enclosure supports seamless indoor or outdoor deployment, making it ideal for dockside pedestals or onboard systems.

Core Advantages for Boat Owners and Marina Operators

  • Shielded Purity: Dual full current-carrying shields eliminate electromagnetic interference, providing ultra-clean power for AV systems, navigation gear, and inverters—far surpassing standard transformers.
  • ISO-Boost Innovation: Automatically compensates for low input voltages common in remote marinas, boosting output to optimal levels without manual intervention.
  • Silent Performance: Operates at sound levels well below NEMA guidelines, minimizing disturbances in quiet anchorages or busy harbors.
  • Vibration Resistance: Built to withstand the constant motion of marine settings, reducing wear and maintenance needs.
  • Flexible Voltage Handling: 12.5% taps allow precise adjustments to match varying shore power supplies.

Technical Excellence Backed by Rigorous Standards

Certified to UL listing, CSA, and exceeding ABYC's stringent 4000 Volt HIPOT test, this transformer meets or surpasses NEMA, ANSI, and OSHA requirements. Its long-life insulation system—UL Class 155°C for smaller units, escalating to 180°C with 115°C rise for 1kVA and above—guarantees durability under heavy loads.

Compact yet powerful, it measures 18.44 inches in height, 16.13 inches in width, and 13.34 inches in depth, fitting effortlessly into tight marina spaces without sacrificing capacity.

Real-World Marine Benefits

Galvanic corrosion is a silent killer for boat hulls and through-hulls. By fully isolating the vessel's electrical system from shore power, the HBL100AITSSB prevents stray currents that cause electrolysis, extending the life of zinc anodes and underwater metals. Marina managers appreciate its role in stabilizing pedestal power for multiple slips, reducing nuisance trips and costly repairs.

For luxury yachts, the quiet, noise-filtered output ensures crystal-clear audio and video, while protecting high-end appliances from surges. In low-voltage scenarios—like extended docks or generator backups—ISO-Boost maintains consistent 120/240V delivery, avoiding dim lights or sluggish motors.

Versatile Applications in Marine Environments

Whether outfitting a superyacht, upgrading marina infrastructure, or safeguarding a weekend cruiser, this transformer's versatility shines. It's particularly valuable in:

  • High-traffic marinas with inconsistent utility feeds.
  • Off-grid locations relying on long cable runs.
  • Liveaboard setups demanding 24/7 power purity.
  • Commercial vessels needing ABYC-compliant isolation.

Users report fewer galvanic isolator failures and smoother inverter synchronization, thanks to the transformer's superior filtering. Its encapsulated construction resists the tropical humidity of Florida keys or the salty gales of New England coasts alike.

Effortless Ownership and Long-Term Value

Maintenance is minimal: routine visual inspections and tap adjustments suffice. The corrosion-proof encapsulation means no worries about salt spray or rain ingress. With a design proven in thousands of installations, it offers peace of mind and a strong return on investment through reduced downtime and equipment protection.

Frequently Asked Questions

What makes the Hubbell HBL100AITSSB ideal for marine use?

Tailored for boats and marinas, it provides galvanic isolation to prevent corrosion, cleans noisy shore power, and includes ISO-Boost for voltage stabilization in low-supply areas. Dual shields and encapsulation ensure reliability in wet, salty conditions.

How does ISO-Boost work on this isolation transformer?

ISO-Boost automatically detects and corrects undervoltage from long shore cords or weak pedestals, delivering stable output voltages like 120/240V without user adjustments.

Is the HBL100AITSSB suitable for outdoor installation?

Yes, its UL Type 3R enclosure is rainproof and corrosion-resistant, perfect for dockside or exposed marine environments.

What certifications does this transformer hold?

UL listed, CSA certified, ABYC-compliant (exceeds 4000V HIPOT), and meets NEMA, ANSI, and OSHA standards for safety and performance.

How quiet is the operation compared to other transformers?

Sound levels are significantly below NEMA standards, thanks to vibration-resistant mounting and quality core design—ideal for noise-sensitive marinas.

What are the physical dimensions of the unit?

It measures 18.44 inches high, 16.13 inches wide, and 13.34 inches deep, offering a compact footprint for tight installations.

Does it include voltage taps for flexibility?

Yes, equipped with 12.5% taps to fine-tune input/output matching various shore power configurations.

Why choose an encapsulated design over dry-type transformers?

Encapsulation with silica and resin seals out moisture and air, preventing corrosion and insulation breakdown—crucial for marine longevity.
