RCBO
1P+N 18mm RCBO 6kA — Type A / AC, 1–40A
The TPKELE TPK L6-40 is a 1P+N double-break RCBO that fits earth leakage, overload and short-circuit protection into one 18mm DIN-rail module. Rated 1A–40A at 230V AC with 6kA breaking capacity and 100% service breaking, it is available in B or C curve with 10 / 30 / 50 / 100 mA sensitivity in Type A or Type AC — built to IEC/EN 61009-1 and AS/NZS 61009.1 for one-RCBO-per-circuit switchboards in Australia, New Zealand and global 230V markets.

Frequently Asked Questions
What is the difference between an RCBO and an RCCB?
An RCCB (RCD) only detects earth leakage and has no overcurrent protection, so it must be paired with MCBs. An RCBO combines residual current protection with thermal-magnetic overload and short-circuit protection in one device, so each circuit gets its own leakage protection and a fault on one circuit does not trip the others.
Type A or Type AC — which should I choose?
Type AC detects sinusoidal AC residual current only. Type A also detects pulsating DC residual current produced by inverters, induction cooktops, LED drivers, variable-speed appliances and EV chargers. Type A is the safer default for modern installations and is increasingly specified in Australia, New Zealand and Europe.
Which residual current rating do I need?
30 mA is the standard for personal protection on final circuits. 10 mA is used for special locations such as medical areas and some wet locations. 50 mA and 100 mA are used for equipment or fire protection where personal protection is provided elsewhere.
Can the RCBO be used on EV charger circuits?
Yes — a Type A RCBO can protect an EV charger circuit when the charger has built-in 6 mA DC residual current detection (RDC-DD). Where the charger has no DC detection, a Type B device or a Type A RCBO plus a separate RDC-DD is required.
Do you support OEM branding for RCBOs?
Yes — logo printing, housing print, rating labels and packaging can be customised for distributor and brand-owner programs. Samples are available within 5–10 working days.
