Tesla MCB1P63 Single Pole 63 Amp 6kA C Curve Miniature Circuit Breaker

Description

Sixty-three amps, single phase. The highest-rated 1P MCB in the range.

The Tesla MCB1P63 is a Single Pole 63A 6kA C Curve Miniature Circuit Breaker built to IEC/EN60898 — the highest-rated single-pole MCB in the Tesla HPC2 range. Specified as the main incomer on large single-phase distribution boards, for direct protection of the heaviest single-phase plant, and for critical power systems on remote Australian industrial and mining sites where no lower rating is sufficient.

• Single Pole / 63A / 6kA breaking capacity
• C Curve — general-purpose, handles moderate inrush
• 240V AC / 50-60Hz
• Thermal-magnetic trip — bi-metal overload + magnetic short-circuit
• DIN rail mount — 1 module width, 35mm rail
• Pillar clamp terminal — rigid conductor up to 25mm²
• IP20 rated for enclosed switchboard installation
• IEC/EN60898 — Australian approval number V08030
• Mechanical life: 10,000 cycles | Electrical life: 4,000 cycles
• HPC2 Series — highest rating in the 10A to 63A single-pole range

Maximum Capacity. Same Compact Footprint.

At 63A, the MCB1P63 is the ceiling of the HPC2 single-pole range — and the only choice when 50A is not enough. As a main incomer, it protects large single-phase distribution boards in major industrial and infrastructure facilities. As a direct equipment breaker, it handles the largest single-phase plant and machinery loads where no standard MCB rating below 63A is sufficient. On remote and off-grid sites — mine site camps, drill rigs, hybrid power systems — it serves as the main switch on large single-phase power systems where reliability is non-negotiable.

The thermal-magnetic trip delivers bi-metal protection for sustained overloads and magnetic trip for instantaneous short-circuit response — at 6kA, rated for Australian industrial switchboard fault levels. Despite the 63A rating, it stays at 1 module wide — same footprint as the 10A at the other end of the range.

One Range, All Ratings

The HPC2 Series runs from 10A to 63A in single-pole, with matching three-pole variants across the range. One supplier, one approval number (V08030), one product family — from the smallest residential lighting circuit to the largest single-phase main incomer. For load or fault level requirements beyond the MCB1P63, a Moulded Case Circuit Breaker (MCCB) would be the next step.

Q: Is 63A the highest single-pole MCB available in the Tesla range?
A: Yes — 63A is the highest rating in the Tesla HPC2 single-pole 6kA MCB range. For applications requiring single-phase overcurrent protection above 63A, a Moulded Case Circuit Breaker (MCCB) would typically be specified instead.

Q: Is the Tesla MCB1P63 approved for use in Australian switchboards?
A: Yes. The MCB1P63 carries Australian regulatory approval number V08030 and is manufactured to IEC/EN60898. It is suitable for use in compliant Australian residential, commercial, industrial, and mining switchboard installations.

Q: What conductor sizes does the MCB1P63 accept?
A: The pillar clamp terminal accepts rigid (solid or stranded) copper conductors up to 25mm². Always confirm cable sizing against the circuit load, installation method, and AS/NZS 3000 for 63A single-phase circuit requirements.
