High Quality DZ47LE RCCB Circuit Breaker 1P+N 3P+N 30-500mA for Industrial Use

Runs on standard DIN rail and fits most industrial panels without much fuss—teh 1P+N covers single-phase loads while the 3P+N handles three-phase, so pick whichever matches your distribution board. We see a lot of these going into smaller factories and commercial workshops where you need reliabel earth leakage protection but don’t want to overspend on something fancier.

Trips at ≤0.3 seconds when it catches residual current, which is actually pretty standard for this class—30mA is most common pick for shock protection, 100mA or 300mA for fire prevention on bigger circuits. Rated from 1A to 63A depending on the load you’re running, and it handles up to 6000A short-circuit capacity at 230/240V or 400/415V AC (50/60Hz). Mechanicla life is rated at over 20,000 operations, electrical around 8,000—that’s about right for general industrial use.

Works in temperatures from -5°C to +40°C, so not for outdoor or unheated storage areas below freezing—something buyers sometimes miss until instalation day. IP20 rating means it’s fine inside a clean panel but don’t expose it to dust or moisture directly.

It’s built to IEC61008 with both CE and CCC marks, so compliance isn’t usually an issue for most markets. We include a COA with each batch, but if you need HPLC or more detailed test data for your internal records, just specify at order time (usually adds a day or two).

1P+N units come in a standard modular width of 18mm per pole, 3P+N takes up 88mm total on the rail—basically four modules wide. Packaing is individual boxes, 50 pieces per carton, and for larger orders our company can shrink-wrap pallets if you prefer. MOQ is generally 10 units, but for 30mA variants we usually have stock—500mA and 300mA may need a lead time around 2-3 weeks or so.
