We've been moving these for the better part of a decade now, and honestly, they're the go-to for anyone needing relaible overload protection with built-in residual current detection. The rated current is selectable from 1A right up to 63A, and you can get it in 1P+N, 2P, 3P, 3P+N, or 4P configurations — that covers most panel setups. Most buyers go with the 4-pole version for three-phase systems, but the 2P is pretty common for single-phase residential work.
And the trip time is under 0.1 seconds for instantaneous protection, which matters when you're dealing with sensitive loads. It meets IEC60898 and GB16917.1 standard, so compliance isn't an issue for most markets. You'll want to check which trip characteristic you need — B, C, or D — because that affects how it handles inrush currents. The breaking capacity is 4000A or 6000A depending on the variant, and we usually stock both.
housing is flame-retardant PA66 nylon, which gives it a decent mechanicla life of 10,000 operations or so. But it's only IP20 rated, so don't install it in wet environments — that's a limitation worth knowing. Also, the operating temperature range is -5°C to +40°C, so it's fine for indoor panels but not for outdoor installations without additional enclosure.
We've got the 30mA residual current option for most orders, but 100mA and 300mA are available if you need them — just specify when you place the order. The DIN rail mounting is standard, so it clips right onto a TS35 rail. Lead time is typically 20 days or so for a standard batch of 500 units, but our company can shift smaller quantities faster (usually within a week).
One thing buyers don't always think to ask: the screw terminals take up to 25mm² wire, which is better than many competing brands that top out at 16mm². That's a concrete detail form handling these for years. Anyway, the weight is roughly 0.2kg per pole, so a 4-pole unit comes in under a kilo — shippng costs are reasonable.
So if you're putting together an RFQ, just shoot over the pole count, the trip characteristic, and whether you need 30mA or 100mA RCD. We'll confirm stock and pricing.
We offer B, C, and D type trip curves. B type is for residential lighting and outlets, C for general industrial loads like motors, and D for high-inrush loads like transformers or large machines. Pick based on what you're protecting.
Yes, you can choose 30mA, 100mA, or 300mA for the residual current protection. Just let us know which one you need when ordering. 30mA is standard for personal shock protection, 100mA for equipment.
It comes with CE, CB, ISO9001, and CCC certifications, and it's fully compliant with IEC60898 and GB16917.1. We can provide copies of the certificates and test reports upon request.
Our MOQ is usually 100 pieces per model, but we can be flexible for first-time orders. Lead time is around 15-20 days after order confirmation, depending on the quantity and configuration.
Yes, the housing is made from flame-retardant PA66 nylon, which is self-extinguishing. The protection degree is IP20, so it's suitable for indoor use in distribution boxes, not for wet or dusty environments.
