5A Electronic Circuit Breaker Module 5–60V DC | LED Indicators
5A Electronic Circuit Breaker Module | 5–60V DC | Resettable Overcurrent Protection
Keep your low-voltage projects safe and running smoothly with this compact 5A Electronic Circuit Breaker PCB Module. Designed for DC circuits operating between 5V and 60V, this resettable breaker board automatically cuts output when a short circuit or overcurrent condition is detected — then recovers on its own, so there's no need to manually reset a mechanical breaker. The integrated LED indicators let you know at a glance exactly what's happening with your circuit.
Made in Mainland China.
Key Features
- Resettable Fault Response: Automatically cuts output on short circuit detection, handles short-duration overloads, then self-recovers — keeping your project running without manual intervention.
- Screw Terminal Connections: Input and output screw connectors keep wiring neat and secure, making installation quick and reliable for both prototyping and permanent installations.
- Four Corner Mounting Holes: Integration-ready PCB layout with mounting holes for easy placement inside an equipment enclosure or project box.
- Defined Electrical Parameters: Supports 5–60V DC input with 5A continuous rated current. Low-resistance design minimises energy loss during normal operation.
-
Three-State LED Indicator System:
- Blue: Normal operation
- Red: Short-circuit cutoff active
- Red + Flashing Blue: Output overcurrent condition
- Versatile Use Cases: Ideal for small battery packs, bench power supplies, microcontroller development boards, model equipment, low-voltage vehicle electronics, and electronics repair workbenches.

Frequently Asked Questions
Q: What voltage range does this electronic circuit breaker module support?
A: This circuit breaker PCB module supports DC input voltages from 5V to 60V, making it suitable for a wide range of low-voltage electronics projects including battery packs, microcontroller setups, and bench power supplies.
Q: Does the circuit breaker module require manual resetting after a fault?
A: No — the module features an automatic self-recovery function. After detecting and responding to a short circuit or overcurrent condition, it will automatically restore output once the fault clears, eliminating the need for manual intervention.
Q: What do the LED indicator colours mean on this breaker board?
A: The three-state LED system provides instant visual status feedback: a solid blue light means normal operation; a solid red light means a short-circuit cutoff is active; and a red light with flashing blue indicates an output overcurrent condition is present.
Q: Can this module be mounted inside an enclosure?
A: Yes — the PCB includes four corner mounting holes, allowing you to securely install it inside a project box or equipment enclosure for a clean, professional finish.
