Tesla RCBO6K25 Single Pole 25 Amp 6kA 30mA Type A RCBO Safety Switch

Description

EV charger ready. Type A RCBO. Twenty-five amps in one slim module.

The Tesla RCBO6K25 is a Single Pole 25A 6kA 30mA Type A RCBO built to AS/NZS 61009.1. It combines residual current (earth leakage) and overcurrent (circuit breaker) protection in a single 1P+N DIN rail device — the go-to choice for EV home charger installations, larger single-phase air conditioners, and high-capacity dedicated appliance circuits requiring combined RCD and MCB protection in Australian residential and commercial switchboards.

The EV Charger RCBO — Type A Where It Counts

As EV adoption accelerates across Australia, the 25A Type A RCBO has become one of the fastest-growing circuit protection ratings on residential switchboard jobs. Single-phase EV home chargers rated at or below approximately 6kW draw up to 25A continuous — and the onboard charger electronics generate pulsating DC fault currents that a Type AC RCBO won't detect. The RCBO6K25 delivers 25A overcurrent protection and Type A 30mA earth leakage in a single 18mm module. No separate MCB and RCD required.

Also Suited to Larger Air Conditioning and High-Draw Appliances

Beyond EV chargers, the 25A rating covers higher-draw single-phase ducted and split system air conditioners, large commercial kitchen appliances, and high-capacity dedicated circuits where 20A is insufficient. In each case, the Type A characteristic provides earth leakage protection compatible with the inverter and switch-mode electronics in modern equipment. Each circuit is protected independently — a trip on one doesn't affect any other.

Termination and Installation

Clips straight onto 35mm DIN rail. The pillar clamp terminal accepts rigid conductors up to 25mm² — no ferrules required. At 18mm wide (1 module), it occupies the same footprint as a single MCB. IP20 is appropriate for any enclosed switchboard or distribution enclosure. Operating temperature -5°C to 55°C.

Q: Is a Type A RCBO required for an EV charger installation?
A: Many EV charger manufacturers specify Type A as the minimum required earth leakage protection type, as EV onboard charger electronics can generate pulsating DC fault currents that Type AC RCBOs won't detect. Always check the charger manufacturer's installation guide for the specified RCBO or RCD type, and confirm with AS/NZS 3000 requirements. The RCBO6K25 is Type A and 25A — correctly rated for most single-phase EV home charger circuits up to approximately 6kW.

Q: Is the Tesla RCBO6K25 approved for use in Australian switchboards?
A: Yes. The RCBO6K25 is built to AS/NZS 61009.1 with Australian approval number SGS-210384-EA. It is suitable for use in compliant Australian residential, commercial, and light industrial switchboard installations.

Q: What is the difference between the RCBO6K25 and RCBO6K32?
A: Both are Tesla RCBO6K range 1P+N, 6kA, 30mA, Type A RCBOs with identical construction, approval, and 18mm footprint. The RCBO6K25 is rated 25A — suited to EV chargers up to approximately 6kW and larger air conditioning circuits. The RCBO6K32 is rated 32A — suited to higher-output EV chargers (7.2kW / ~32A) and heavy single-phase equipment circuits. Choose based on the circuit load and cable sizing.
