Tesla MCB1P50 Single Pole 50 Amp 6kA C Curve Miniature Circuit Breaker

Description

Fifty amps, single phase. Specialist rating for heavy plant and large sub-mains.

The Tesla MCB1P50 is a Single Pole 50A 6kA C Curve Miniature Circuit Breaker built to IEC/EN60898. At 50A it is one of the highest-rated single-pole MCBs available — specified for heavy plant main switch duties, large single-phase sub-main incomers, and specialist industrial and resources sector applications where standard ratings fall short.

• Single Pole / 50A / 6kA breaking capacity

Specialist Capacity, Standard Footprint

The 50A single pole MCB is a specialist rating — reached for when 40A is insufficient and a compact single-phase solution is needed over a three-phase alternative. On mine sites, remote installations, and heavy industrial facilities, it serves as the main isolating circuit breaker on large single-phase plant and as a high-capacity sub-main incomer feeding major single-phase distribution in industrial switchboards, warehouses, and large commercial buildings.

The thermal-magnetic trip delivers two-stage protection: bi-metal for sustained overloads, magnetic for instantaneous short-circuit response. At 6kA it handles fault levels typical in Australian industrial switchboards. Despite the 50A rating, the HPC2 construction keeps it at 1 module wide — the same compact footprint as every other single-pole MCB in the range.

Termination and Installation

Clips straight onto 35mm DIN rail. The pillar clamp terminal accepts rigid conductors up to 25mm² — no ferrules required. IP20 is appropriate for any enclosed switchboard or distribution enclosure. Manufactured to IEC/EN60898 with approval number V08030, it meets Australian regulatory requirements for circuit protection devices on regulated industrial and mine sites.

Q: When is a 50A single pole MCB used instead of a 40A?
A: Choose 50A when the calculated circuit load or cable sizing exceeds the 40A rating — typically for large single-phase plant main switch duties, high-capacity sub-main feeds, or specialist industrial and mining applications where 40A is insufficient. Always confirm circuit sizing with load calculations and AS/NZS 3000.

Q: Is the Tesla MCB1P50 approved for use in Australian switchboards?
A: Yes. The MCB1P50 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 MCB1P50 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 50A circuit requirements.
