Tesla MCB3P63 3 Pole 63 Amp 6kA C Curve Miniature Circuit Breaker

Description

Sixty-three amps. Top of the range. Maximum capacity, minimum footprint.

The Tesla MCB3P63 is a 3 Pole 63A 6kA C Curve Miniature Circuit Breaker built to IEC/EN60898 — the highest-rated MCB in the Tesla HPC2 three-pole range. Specified as the main incomer on commercial and industrial distribution boards, and for direct protection of the heaviest three-phase loads, the MCB3P63 delivers maximum capacity in a standard 3 module DIN rail footprint.

• 3 Pole / 63A / 6kA breaking capacity
• C Curve — general-purpose, handles moderate inrush
• 415V AC / 50-60Hz
• Thermal-magnetic trip — bi-metal overload + magnetic short-circuit

Maximum Capacity, Standard Footprint

At 63A, the MCB3P63 is the ceiling of the HPC2 three-pole range — and one of the most frequently specified ratings on commercial and industrial jobs. As a main incomer, it's the standard choice for commercial three-phase distribution boards where the incoming supply needs protection before feeding downstream circuits. As a direct equipment breaker, it handles the heaviest three-phase loads: large pumping stations, process machinery, significant sub-main feeds to warehouses, shopping centres, and large commercial buildings. The thermal-magnetic trip delivers bi-metal protection for sustained overloads and magnetic trip for instantaneous short-circuit response — at 6kA, rated for Australian commercial and industrial fault levels.

Termination and Installation

Clips straight onto 35mm DIN rail. The pillar clamp terminal accepts rigid conductors up to 25mm² — no ferrules required. Despite the 63A rating, it stays at 3 modules wide — the same compact footprint as every other MCB in the HPC2 range, keeping even high-capacity boards tidy.

One Range, All Ratings

The HPC2 Series runs from 10A to 63A in three-pole, with matching single-pole variants across the range. One supplier, one approval number (V08030), one product family — from the smallest sub-circuit to the main incomer.

Q: Is 63A the correct main incomer rating for a commercial three-phase distribution board?
A: 63A is one of the most commonly specified main incomer ratings for commercial three-phase boards in Australia, but the correct rating depends on the board's maximum demand calculation, the incoming cable size, and the upstream protection. Always confirm incomer sizing with a licensed electrician in accordance with AS/NZS 3000.

Q: Is the Tesla MCB3P63 approved for use in Australian switchboards?
A: Yes. The MCB3P63 carries Australian regulatory approval number V08030 and is manufactured to IEC/EN60898. It is suitable for use in compliant Australian switchboard installations.

Q: Is there a higher-rated three-phase MCB available in the Tesla range?
A: No — 63A is the highest rating in the Tesla HPC2 three-pole 6kA MCB range. For fault levels or load requirements beyond the MCB3P63, a Moulded Case Circuit Breaker (MCCB) would typically be specified instead.
