Tesla MCB1P25 Single Pole 25 Amp 6kA C Curve Miniature Circuit Breaker

Description

Twenty-five amps, single phase. EV chargers, large air con, heavy appliances.

The Tesla MCB1P25 is a Single Pole 25A 6kA C Curve Miniature Circuit Breaker built to IEC/EN60898. At 25A it bridges standard appliance circuits and heavier single-phase dedicated loads — the go-to rating for EV home chargers, larger split system air conditioners, and commercial kitchen equipment across Australian residential and commercial switchboards.

The EV Charger Circuit Breaker — and More

As EV adoption accelerates across Australia, the 25A single pole MCB has become one of the fastest-growing ratings on residential jobs. Single-phase home EV chargers (7.2kW) typically draw around 32A at peak — but a 25A breaker is widely specified for chargers rated at or below 6kW (approximately 25A continuous), making the MCB1P25 a natural fit for home charging installations. Always confirm the charger's rated input current and cable sizing against AS/NZS 3000 before selecting the breaker rating.

Beyond EV chargers, the 25A rating handles larger single-phase split system air conditioners, commercial kitchen appliances, and dedicated sub-circuit feeds in commercial switchboards where 20A leaves insufficient headroom. The thermal-magnetic trip delivers bi-metal protection for sustained overloads and magnetic trip for instantaneous short-circuit response — at 6kA, rated for Australian residential and commercial fault levels.

Termination and Installation

Clips straight onto 35mm DIN rail. The pillar clamp terminal accepts rigid conductors up to 25mm² — no ferrules required. At 1 module wide it keeps boards compact even when dedicated circuits multiply. IP20 is appropriate for any enclosed switchboard or distribution enclosure.

Q: Is the MCB1P25 suitable for an EV home charger circuit?
A: Yes — 25A is a commonly specified breaker rating for single-phase home EV charger installations rated at or below approximately 6kW. The correct breaker rating depends on the charger's rated input current, cable sizing, and wiring method. Always confirm with the charger manufacturer's installation guide and AS/NZS 3000 before installation by a licensed electrician.

Q: Is the Tesla MCB1P25 approved for use in Australian switchboards?
A: Yes. The MCB1P25 carries Australian regulatory approval number V08030 and is manufactured to IEC/EN60898. It is suitable for use in compliant Australian residential, commercial, and light industrial switchboard installations.

Q: What conductor sizes does the MCB1P25 accept?
A: The pillar clamp terminal accepts rigid (solid or stranded) copper conductors up to 25mm². This covers conductor sizes typically associated with a 25A single-phase dedicated circuit in residential and commercial switchboard applications.
