Amass XT60 XT30 Fuse Smoke Plug, Tester Circuit Breaker
Product Details
Product Description
The Amass XT60 XT30 Fuse Smoke Plug / Tester Circuit Breaker (1–6S Safety Plug) is a premium in-line protection device (smoke stopper) designed to safely test and power electronic systems such as FPV drones, RC aircraft, LiPo battery setups, ESCs, and embedded electronics. It acts as a resettable circuit breaker that prevents permanent damage during first power-up or troubleshooting by limiting current in case of a short circuit.
When connected between the battery and your device, it allows normal power flow if the circuit is correct. If a short or wiring fault is detected, it immediately limits current and “trips†the protection, preventing smoke, burnt components, and ESC/flight controller damage.
Key Function
- Works as a temporary safety fuse + circuit breaker
- Protects electronics during first power-on testing
- Immediately reacts to short circuits or abnormal current draw
- Uses a resettable PTC fuse system
- Typically indicates status via LED (normal vs fault condition)
In simple terms: it’s a “first power-on insurance device†for drone builds.
Key Features
- Compatible with XT30 and XT60 connectors
- Supports 1–6S LiPo systems (up to ~30V)
- Built-in resettable PTC fuse protection
- Typical protection values:
- Hold current: ~0.5A
- Trip current: ~1A (varies slightly by model)
- Fast response to short circuits (milliseconds-level cutoff behavior)
- LED indicator for power/fault status (model dependent)
- Reusable after fault removal (auto-reset type protection)
- Lightweight and portable design
- Designed specifically for drone/RC safety testing
Applications & Use Cases
- First power-on testing of FPV drones
- ESC, flight controller, and wiring verification
- Battery pack safety checks
- RC aircraft and robotics debugging

Why Choose This Device?
This smoke stopper is one of the most important low-cost safety tools in drone building. Instead of risking expensive ESCs, flight controllers, or batteries during first power-up, it gives you a controlled current limit so mistakes don’t instantly destroy components.
It is especially useful because even experienced builders can accidentally create shorts while soldering or wiring—this device acts as a fail-safe layer between your battery and electronics.
