You’ve got a combined earth leakage and overload protector here, all in one compact DIN-mounted unit — it’s basically an RCD and MCB in a single housing, which saves panel space and wiring time, especially for solar PV setups where you’re cramming everything into a tight enclosure anyway.

Breaking capacity is 6000A, which is fine for most residential and light commercial distribution boards, and the tripping curves come in B, C, or D so you can match it to the load type — motor starts or lighting circuits, for instance — and the bi-connect terminals let you daisy-chain busbars or cable directly without extra adapters.

RCBO Circuit Breaker

It’s 230/400V AC at 50 or 60Hz, covering single-phase and three-phase systems, and the IP20 enclosure means it’s strictly indoor use — don’t put it in a wet outdoor box without a proper weatherproof enclosure, because of that it’s not sealed for that.

RCBO Installation

We usually stock the 2P and 4P versions in 6A to 63A ranges, with roughly 20 days or so lead time on the 1P+N and 3P+N if they’re not on the shelf, and CE, CB, CCC, and SAA certifications are on the COA with each batch, but it’s worth confirming which cert you need for your local grid compliance before ordering.

RCBO Specifications

One detail you might not think to ask: arc-extinguishing chamber is air-based, not gas, so it’s heavier than some compact designs but more reliabel for repeated fault clearing in solar systems where surges can happen.

For the 4P model, most buyers go with the 63A rated current for main incomers in three-phase boards, but if you’re doing sub-distribution, the 32A or 40A versions are actually easier to handle during instalation — less lug torque required, and teh terminals accept up to 25mm² cable.

Frequently Asked Questions

Can I mix different rated currents (e.g., 10A, 20A, 32A) in a single 4P RCBO order?

Yes, you can mix different rated currents in the same order for 4P units. Just let us know the exact amperage for each pole when you place the order, and we'll handle the configuration.

What's your typical lead time for a bulk order of 500 units of the 2P ESR Series RCBO?

For a standard order of 500 units, lead time is usually 15-20 working days from order confirmation, depending on the pole configuration and rating mix. We can expedite if you need a partial shipment sooner.

Do you provide SAA certification documents with the shipment for the Australian solar market?

Absolutely, SAA certification is included for models destined for Australia. We supply the certificate and test report with each shipment, so your compliance paperwork is sorted.

What's the maximum busbar thickness the bi-connect terminals can accept?

The bi-connect terminals accept busbars up to 10mm width and 2mm thickness. For thicker busbars, just let us know and we can adjust the terminal design accordingly.

Can you customize the RCBO to trip at a lower residual current for PV applications?

Yes, we can adjust the residual current sensitivity to 30mA or 100mA as needed for solar PV systems. Just specify your requirement when ordering, and we'll set it up during production.
