Gaqqee M3050/M3056 AC Current Sensing Switch 30A | CE RoHS
Gaqqee M3050/M3056 AC Current Sensing Switch 30A | CE RoHS
Gaqqee M3050 / M3056 AC Current Sensing Relay Switch – 0.2A to 30A
The Gaqqee M3050 (Normally Open) and M3056 (Normally Closed) are precision AC current detection switches designed for reliable, non-contact monitoring in electrical control and automation systems. With an adjustable threshold from 0.2A to 30A and fast automatic reset, these compact switches are ideal for HVAC interlocking, motor monitoring, fan control, pump circuits, and DIY electrical projects. CE and RoHS certified.
Made in Mainland China.
Key Features
- Automatic Activation & Reset: Output switch activates when through-hole current exceeds the set threshold; resets automatically when current falls below it — no manual intervention needed.
- Wide Monitoring Range: Detects AC current from 0.2A up to 30A with a fully adjustable threshold to suit your application.
- Ultra-Low Hysteresis (<1%): Ensures consistent, repeatable switching performance, even in strong magnetic environments.
- Non-Contact Electronic Switch: Fast response time with unlimited switching cycles — no mechanical wear, no contact degradation.
- Safe Isolation: Current transformer design keeps input and output fully isolated; the unit is self-powered — no external power supply required.
- Durable, Flame-Retardant Housing: Environmentally friendly PC (polycarbonate) material with flame-retardant properties for safe installation in electrical enclosures.
- CE & RoHS Certified: Meets European safety and environmental compliance standards.

Frequently Asked Questions
Q: What is the difference between the M3050 and M3056 current sensing switch?
A: The M3050 is a normally open (NO) switch — its output circuit is open at rest and closes when the monitored current exceeds the set threshold. The M3056 is a normally closed (NC) switch — its output circuit is closed at rest and opens when the current exceeds the threshold. Choose the model that matches your circuit's control logic.
Q: Does the M3050/M3056 require an external power supply?
A: No. The Gaqqee M3050 and M3056 are self-powered via their internal current transformer design. They draw energy directly from the AC line being monitored, so no separate power supply is needed, simplifying installation significantly.
Q: What wire size can pass through the monitoring hole?
A: The through-hole accommodates wires or cables up to 10 mm in diameter. Simply pass a single AC conductor through the opening to enable non-contact current detection.
Q: Can this switch be used in industrial or high-interference environments?
A: Yes. The M3050/M3056 is specifically designed for use in strong magnetic environments with a hysteresis of less than 1%. Its non-contact, transformer-based isolation ensures robust, stable operation even in electrically noisy industrial settings. Operating temperature range is -20°C to 55°C.
