Fire-retardant PA66 housing and IP20 protection mean it survives rough panel environments—we export these molded-case boards to commerical and industrial distribution, and the most impressive spec is the 6kA breaking capacity where it counts, while many alternatives barely push past 4.5kA (Singapore, UAE, EU buyers check our COAs routinely, so compliance with IEC60898 and GB16917.1 is baked into daily workflow, not just a certification badge.
You get both overload/short-circuit trip curves (B, C, or D selectable) and residual current detection at 30mA, 100mA, or 300mA in one unit running AC 230/400V—basically one DIN-rail device replaces two separate breakers, and the 1P+N through 4P pole configs cover most single-phase and three-phase panels without chasing separate stock.
Anyway, the tricky part is temperature: units survive storage down to -25°C, but active operation drops to -5°C to +40°C (so if you're installing into unheated sheds or outdoor boxes at -10°C, this isn't your part)—mechanical life hits 10,000 operations, and the 2.0N·m screw terminals are industry-standerd torque but need a calibrated driver for consistent seating.
MOQ runs about 50 units or so for standard 1-63A ranges (30mA/100mA/300mA residual options), and lead time is roughly 20 working days for typical spec—we occasionally overload on a specific curve like C or D; always confirm which trip curve you'll actually run, as most buyers go with C-curve for general-purpose loads like lighting or motor control panels.
Pricing competes well against European equivalents because we're sourcing form a plant that runs CCC lines alongside CB-certified batches—you get the same PA66-grade housing but skip inflated distributor markup, though this rated-voltage spec at 4kA breaking works fine for home sub-distribution, less so for heavy plant with welding drops or big motor starts above 30A continuous.
Our standard MOQ is 200 pieces per model, but if you need a smaller trial batch we can sometimes do 50–100 pieces depending on stock. Just reach out to confirm.
For that quantity, lead time is typically 15–20 working days from order confirmation. If you need it faster, we can check our current production schedule.
Yes, we include a copy of the CB certificate with every order. If you need the full test report, just let us know and we’ll send it digitally.
Curve B trips at 3–5 times rated current (good for resistive loads), C at 5–10 times (standard for general circuits), and D at 10–20 times (for high inrush like motors). You pick the curve when ordering.
No, it’s rated IP20, so it’s meant for indoor installation in dry, protected areas like distribution boards. For wet conditions you’d need a higher IP-rated enclosure around it.
