Blue Sea Systems Waterproof Switch Boot (Clear) — Part 4135
The Blue Sea Systems 4135 clear waterproof boot protects push-button reset circuit breakers from moisture, salt air, and accidental contact. It installs in place of the breaker's standard mounting nut, so protection goes on without rewiring the panel, and the UV-resistant material resists discolouration and cracking season after season.

Parts Desk Insights
- Best use case: Protecting a push-button reset circuit breaker from moisture, salt air, and accidental switching on a boat that is exposed to weather.
- Most common customer mistake: Ordering the boot for a breaker style it does not fit. This boot replaces the standard mounting nut on thermal push-button reset breakers only, so confirm the breaker's style and mounting before ordering.
- Sizing and fitment guidance: Check that your breaker is a thermal push-button reset unit secured with a standard mounting nut. If the breaker uses a different mounting arrangement, this boot will not seat correctly.
