You're wiring a three-phase industrial press line that pulls 80A sustained with occasional inrush spikes, and the panel needs to combine overload protection with earth leakage in one DIN-mounted device to save space—the SWMLE-100 handles that, and we've shipped these for just that kind of machine builder application for years. 63A or 80A or 100A rated current, pick base on your load calc, and the 10kA breaking capacity covers most commercial and light industrial fault levels without needing upstream fusing.
We stock about 400 units of these at any given time across 1P+N through 4P configurations, but the 3P+N models with Type D curve and 100mA residual tend to move fastest for motor circuits—lead time is usually 2-3 days if we're out of a specific combo. The housing is glass-filled PA66, which handles the arc better than standard nylon during a direct short, and we've seen these survive about 10,000 operations or so before mechanical wear shows up.
Basically the residual current trip can be set at 30mA, 50mA, 100mA, 200mA, or 300mA depending on your installation's leakage tolerance—30mA is code-minimum for personnel protection in most regions, but 100mA works better for equiment with natural leakage from filters or VFDs without nuisance tripping. Trip characteristic Type C trips at 5-10x rated current, Type D at 10-20x, which matters if you're driving motors or transformers that pull high inrush.
What it does is combine overcurrent, short circuit, and earth leakage in one housing—no separate RCD plus MCB needed, and that saves about 30% panel space versus two units in most cases. The arc extinguishing is an air design—it's not sealed gas or vacuum, so you'll hear a snap on high-current interruption, but it meets IEC60947-2 for all its ratings and carries CE, CB, and CCC certs for export. Better than consumer-grade units for sustained industrial use, though it's not suited for DC circuits or 60Hz applications without checking the derating curve first.
Actually one thing buyers don't always think about: the 400V 3P version still switches teh neutral on the 3P+N models, which is required in some national wiring regs but not all—verify your local code before ordering the 4P version if you don't need neutral switching. Also the 100A version has slightly thicker terminals than the 63A, so factor that into busbar compatibilty if you're retrofitting an existing panel.
We typically require a MOQ of 100 pieces, but we can be flexible for sample orders or first-time buyers. Just reach out to us with your quantity.
Lead time is usually 15-20 working days for standard configurations like that. If you need it faster, we can check our stock and expedite.
Yes, we include CE and CB certificates with every batch. If you need the full test reports, just let us know and we'll share them.
Absolutely, we offer both Type C and Type D. Just specify your preference when ordering, and we'll configure it for you.
They can be stored in temperatures from -25°C to +70°C. Keep them in a dry place and they'll be fine for long-term storage.
