Swpeet Thermal Circuit Breaker Assortment Kit, 30pcs (5–30A) with Quick-Connects & Waterproof Caps

Swpeet's 30-piece thermal circuit breaker assortment is a compact kit of push-to-reset breakers (5A–30A) with male quick-connect terminals and waterproof button caps for automotive, marine and industrial use.

If you need a small, ready-to-use selection of thermal reset circuit breakers for repairs, prototypes or fleet maintenance, this kit supplies five common ampere ratings plus protective caps and terminals. The breakers are push-to-reset (they pop out on overload and are manually pressed back in) and mount in a 3/8" (10 mm) round hole. Ratings cover 5A, 10A, 15A, 20A and 30A with compatibility for DC up to 50V and AC up to 125–250V, and the kit is optimized for outdoor or humid environments thanks to waterproof button covers.

How will this kit fit into my repair or DIY toolbox?

Because it contains multiple commonly used ampere values, the assortment eliminates repeated orders and reduces downtime. Each breaker is compact and mounts in a standard 3/8" panel hole, so you can swap components quickly during field repairs or bench projects.

• Includes two pieces each of 5A, 10A, 15A, 20A and 30A breakers.
• Twenty transparent waterproof button caps protect contacts from moisture and dirt.
• Male quick-connect terminals speed installation and removal.
• Push-to-reset design allows fast manual resetting after an overload trip.

Are these breakers suitable for marine, automotive or industrial environments?

The design addresses the common environmental risks found in those settings: splash, condensation and dust. While not a substitute for sealed circuit enclosures, the waterproof caps extend component life and reliability in exposed installations.

• Transparent caps guard the reset button from water and debris.
• Plastic housing and metal internal parts balance corrosion resistance and durability.
• Rated for DC 50V and AC up to 125–250V for versatile usage scenarios.
• Approved to relevant safety standards such as TUV and RoHS where specified.

How do I install and reset these push-button breakers?

Installation is straightforward: press the breaker into a 3/8" (10 mm) round panel cutout, attach wires to the male quick-connect terminals, and secure wiring with compatible female crimp connectors. On overload the button pops out automatically; press it back in to restore the circuit after the fault is corrected.

• Panel mounting requires a 3/8" (10 mm) round hole.
• Use female quick-disconnect terminals sized for the male tabs supplied.
• Do not use the cap as a lock — it protects against water and contamination only.
• Verify correct amp rating for the circuit before replacement to avoid nuisance tripping.

What exactly comes in the package and what can I expect for sizes?

The kit contains 30 pieces total—ten circuit breakers across five ratings and twenty protective caps—packed for quick access. Breakers are small, panel-mounted push-button types suitable for tight instrument panels and control boxes.

• 2 × 5A, 2 × 10A, 2 × 15A, 2 × 20A, 2 × 30A push-to-reset breakers.
• 20 × transparent waterproof button caps to protect reset buttons.
• Male quick-connect terminals integrated on each breaker for rapid wiring.
• Plastic housing with metal contacts for reliable conductivity and low weight.

Who is this for? Technicians, hobbyists and fleet maintainers who work on cars, boats, small industrial equipment, electric tricycles and control panels will find this assortment useful. It’s ideal when you need a range of protection values on hand for diagnostics, emergency fixes or building compact electrical systems where panel space is limited. If you require sealed or switch-rated push-on/push-off devices, consider alternative switch types; this kit is specifically for thermal reset protection and quick field servicing.
