Blue Sea 7066 ATO/ATC-Style Low Profile Circuit Breaker - 2-Pack - 20 Amp

The Blue Sea Systems 7066 ATO/ATC-Style Low Profile Circuit Breaker 2-Pack delivers a manually resettable protection solution that replaces traditional ATO and ATC blade fuses in marine electrical systems. Unlike one-time fuses that require replacement after every fault event, these circuit breakers reset with a manual push-button, eliminating inventory management and downtime in the field.

Each breaker is rated for 20 amps and meets ABYC (American Boat and Yacht Council) circuit protection requirements—the regulatory standard for marine electrical safety. The low-profile design maintains a compact footprint compatible with standard ST-Blade fuse blocks, whether secured with or without a cover. This drop-in replacement format means no rewiring or block modification is needed; the breaker functions identically to the ATO/ATC fuses it supersedes, with the critical advantage of reusability.

The 2-pack configuration serves dual-circuit protection needs or provides a spare for extended operations offshore, in remote locations, or on vessels where supply chains are limited. Operators and marine technicians appreciate circuit breakers over fuses because they reduce logistics burden and provide immediate circuit restoration without carrying replacement inventory. Blue Sea Systems' engineering ensures these breakers respond consistently to overload conditions, protecting wiring and equipment while remaining field-serviceable in critical moments.

The 20-amp rating suits a wide range of marine applications, from navigation and communication systems to lighting and auxiliary power circuits. This product is essential for any operator building or maintaining ABYC-compliant electrical systems who prioritizes reliability and reduced dependence on consumable fuses.
