شنايدر قاطع الصيانة الكهربائي (Domae) أحادي الطور بتيار (20A)

1P indicates one electrical pole (single-pole), 20A is the maximum continuous current it can safely carry, and C-curve describes the trip characteristics, which are suitable for moderate inrush loads such as lighting and small appliances.

Key specs include a 500V rating, 6000A short-circuit current capability, and a breaking capacity around 10kA. It is UL 1077-listed with CE and CCC approvals, and features a thermoplastic housing for durability in typical panel environments.

Power should be off before installation. Mount the MCB on a standard 35mm DIN rail, connect the incoming line to the input terminal and the load to the output terminal, and firmly tighten the terminals. It is designed for easy plug-in installation in compatible panels.

It's well-suited for protecting single-phase circuits in homes or small offices, such as lighting circuits, outlets, and small appliance circuits, where moderate inrush loads are expected.

It carries UL 1077 listing and has CE and CCC approvals. The thermoplastic housing offers UV and corrosion resistance, contributing to overall safety and longevity in typical electrical installations.

If you’re considering alternatives, you can compare with Siemens 1P 20A MCB (https://fepy.com/product/siemens-1p-20a-mcb), ABB 1P 20A MCB (https://fepy.com/product/abb-1p-20a-mcb), or Eaton 1P 20A MCB (https://fepy.com/product/eaton-1p-20a-mcb). Differences may include trip curve nuances (B, C, D), price, and panel compatibility; choose based on your load characteristics and panel ecosystem.

Yes, it is designed for Schneider Electric environments and DIN-rail mounting. Ensure you’re selecting a 1P 20A device with the same voltage rating (500V) and appropriate trip curve for your circuit.

First, switch off the load and reset the breaker. Investigate the fault in the circuit (such as short circuits or overloaded conductors). If the fault is cleared, you can reset the breaker; if it trips repeatedly, consult a qualified electrician to diagnose the underlying issue.

After installation and powering the system, perform a normal-load test by turning on the circuit and confirming the load operates without nuisance trips. For a more thorough check, use a proper breaker tester or have a licensed electrician verify the instantaneous trip and overload protection.

The C-curve is designed for moderate inrush loads like lighting and some electronics. If you expect heavy inrush loads (such as large motors or compressors), you might consider a different curve option (like D-curve) that offers higher instantaneous protection for such loads.
