Kuuma High Temp Limiter - 240V - L1 & L2 Wiring

The Kuuma High Temp Limiter for 240V L1 and L2 wiring is a precision temperature control component designed for marine water heating systems. This limiter protects your onboard hot water system by capping water temperature at 125°F (51.67°C), preventing scalding hazards and extending heater component lifespan during extended cruising or anchoring operations.

Built for Kuuma 240V water heaters, this limiter integrates directly into dual-leg (L1 and L2) electrical configurations commonly found on larger vessels with AC power systems. The 4 x 16-inch form factor fits standard installation locations in engine compartments or utility spaces. At 0.1 lbs, it adds negligible weight while delivering critical thermal regulation that prevents damage from thermal expansion and protects galley systems from excessive heating cycles. The thermostat-based design operates passively—requiring no external power or adjustment once installed—making it a set-and-forget safety component for offshore and coastal cruising.

This component is essential for boaters who rely on permanent or semi-permanent hot water systems aboard cruising sailboats, trawlers, or larger cabin cruisers. Weekend fishermen running extended trips benefit from the reliability and safety margins it provides, while serious offshore anglers and liveaboard cruisers depend on it as part of their comprehensive marine system redundancy. Replacement or preventive installation ensures your water heating system maintains consistent performance without risk of scale formation, corrosion acceleration, or crew discomfort from temperature swings common in marine environments.

Sold as an individual unit. Verify L1/L2 compatibility with your existing Kuuma 240V heater before ordering.
