RATEFPV XT30/XT60 Smoke Stopper, 20ms FPV Short-Circuit and Phase-Short Protector

Overview

The RATEFPV XT30/XT60 Smoke Stopper is an FPV power-system protection tool for checking quadcopter builds, ESC-to-motor wiring, and motor phase connections before normal operation. It is designed to detect direct short circuits and phase-to-phase faults that may occur during a low-throttle motor test, with a 20ms cutoff response.

Key Features

• Detects direct positive-to-negative short circuits and phase-to-phase short conditions between the ESC and motor.
• 20ms cutoff response for fault protection during power-up and testing.
• Green status indication for normal operation; flashing red indication and buzzer alarm when a short is detected.
• Reverse-polarity protection.
• PTC self-resetting protection; clear the fault to reuse the device.
• Available with XT30 or XT60 connectors for FPV power connections.
• Suitable for ESC and motor checks, low-throttle spool-up tests, and FPV build troubleshooting.
