Built for the Board, Rated for the Job

Switchboard builders and electricians need an MCB they can fit and forget. The MCB3P10's thermal-magnetic trip mechanism delivers two-stage protection: a bi-metal strip handles sustained overloads, while a magnetic element trips instantaneously on short-circuit fault current. At 6kA breaking capacity, it's rated for the fault levels typical in commercial and light industrial distribution boards across Australia.

The C Curve characteristic is the right choice where moderate inrush currents are present — resistive and general power loads, lighting circuits, and heating equipment in three-phase sub-boards. It won't nuisance-trip on start-up, but it will clear a genuine fault fast.

Termination and Installation

Clips straight onto 35mm DIN rail. The pillar clamp terminal accepts rigid conductors up to 25mm² — no ferrules required. At 3 modules wide, it keeps multi-circuit boards compact. IP20 is appropriate for use inside any enclosed switchboard or distribution enclosure.

Compliance You Can Specify With Confidence

Manufactured to IEC/EN60898 with Australian regulatory approval number V08030. The HPC2 Series covers the full range from 10A to 63A in both single-pole and three-pole configurations, so one product family handles the whole board.

Q: What is a C Curve MCB and when should I use it?
A: A C Curve MCB trips at 5–10 times its rated current on magnetic (instantaneous) trip. It's designed for general-purpose loads with moderate inrush — including lighting, heating, and general power circuits. For high-inrush motor loads, a D Curve would be used instead. The Tesla MCB3P10 C Curve suits most standard three-phase distribution applications.

Q: Is the Tesla MCB3P10 approved for use in Australian switchboards?
A: Yes. The MCB3P10 carries Australian regulatory approval number V08030 and is manufactured to IEC/EN60898, the applicable standard for miniature circuit breakers. It is suitable for use in compliant Australian switchboard installations.

Q: What conductor sizes does the MCB3P10 accept?
A: The pillar clamp terminal accepts rigid (solid or stranded) copper conductors up to 25mm². This covers the conductor sizes typically used with a 10A circuit in commercial and industrial switchboard applications.
