CHTAIXI Ground Fault Circuit Breaker, 20A
CHTAIXI offers a 20A residential DIN-rail mounted GFCI breaker with earth-leakage protection for 110–120V circuits. It provides a 0.03A residual current trip (≤0.1 seconds) and features silver alloy contacts, a flame-retardant shell, and color indicators for quick status checks. Intended for both protection and isolation tasks in modern panels, it supports fast detection of ground faults while maintaining short-circuit and overload protection.
DIHOOL Ground Fault Breaker With Surge Protection, 50A
The DIHOOL 50A GFCI breaker combines robust ground-fault protection with Type 2 surge protection (20kA) and overcurrent/short-circuit protections. It includes a power and ground LED indicator, a test button, and a visualization window to show ON/OFF status. Suitable for 120V/240V circuits, it accommodates US 110V and 220V installations, making it a versatile choice for resilient DIN-rail protection in mixed-voltage panels.
KERWINN Leakage Protection Circuit Breaker, 20A
KERWINN’s 20A DIN-rail leakage protection circuit breaker focuses on earth leakage and ground fault protection with a flame-retardant thermoset shell and a clear visualization window. It’s designed for solar AC systems and other DIN rail applications, delivering reliable protection with straightforward monitoring on a DIN rail interface.
DIHOOL Ground Fault Circuit Breaker, 63A
This 63A DIHOOL GFCI breaker provides multiple protections including overcurrent, surge protection rated at 20kA as Type 2, and a 30mA leakage protection. It features a status LED, a test button, and a visualization window to indicate ON/OFF. It supports 120V/240V circuits and is designed for 35mm DIN-rail mounting with a compact footprint suitable for larger loads.
CHTAIXI AC Miniature Circuit Breaker, 20A
CHTAIXI’s 20A DIN-rail mounted miniature circuit breaker (MCB) uses a C-curve magnetic trip profile for overload and short-circuit protection across 110–230V AC. It features silver alloy contacts, a flame-retardant shell, and a color indicator for quick status checks. While not a GFCI device, it complements protection schemes for panels requiring a compact overcurrent breaker on the DIN rail.
DIHOOL 15 Amp GFCI Breaker
DIHOOL’s 15A GFCI breaker combines Type 2 surge protection with 30mA leakage protection and additional protections such as overvoltage, overcurrent, and short circuit protection. It includes a power/ground LED indicator, a testing button, and a visualization window. Suitable for 120V/240V circuits, it is a compact option for smaller loads in DIN-rail panels.
ControlGear Mini Circuit Breaker, 15A
ControlGear offers a UL-489 listed 15A miniature circuit breaker designed for 277VAC operation and 60VDC with 10kA short circuit rating. It is intended for din-rail mounting, panel protection, and control gear applications, providing dependable primary protection for circuits requiring a 1-pole C-curve trip.
Buying Guide: Key Considerations For Selecting a DIN Rail GFCI Breaker
When choosing a din rail GFCI breaker, consider the following perspectives to ensure you pick the right device for your panel and load profile:
- Protection Type and Trip Curve: GFCI (ground fault) protection is essential for personal safety, while MCBs guard against overloads. Decide whether you need pure GFCI, a combined RCBO, or a breaker with surge protection for your environment.
- Current Rating and Voltage: Match the amp rating (20A, 15A, 50A, 63A, etc.) to the circuit’s load. Check voltage compatibility for your region (110V/120V vs. 220V–240V).
- Surge and Short-Circuit Protection: Some models include Type 2 surge protection with 20kA ratings. If your panel powers sensitive electronics, surge protection adds resilience against transients.
- Visual Indicators and Status Windows: LEDs or visualization windows help monitor ON/OFF status and fault conditions at a glance, reducing outage investigation time.
- DIN Rail Compatibility and Mounting: Ensure the breaker fits your 35mm DIN rail standard and can be mounted securely within the panel enclosure.
- Isolation and Test Features: A test button for GFCI and a distinct isolation function can simplify maintenance and verification of protective states.
- Flame-Retardant Construction: Safe enclosure materials reduce risk in electrical cabinets, particularly in high-heat environments or where cables are densely packed.
- Brand and Availability: Popular brands with robust support and replacement parts help with long-term maintenance and serviceability.
In practice, for a 110–120V circuit with moderate loads, a 20A GFCI breaker like the DIHOOL or CHTAIXI options often provides a balance of protection and compatibility. For higher-current or multi-branch configurations, a 50A or 63A DIHOOL unit may be appropriate, given the surge protection and multiple protections included. Always consult a licensed electrician for panel modifications and confirm compatibility with your existing electrical system.
