Tesla MCB3P50 3 Pole 50 Amp 6kA C Curve Miniature Circuit Breaker

Description

Fifty amps. Main incomers, heavy plant, one high-capacity breaker.

The Tesla MCB3P50 is a 3 Pole 50A 6kA C Curve Miniature Circuit Breaker built to IEC/EN60898. At 50A it handles both main incomer duties on smaller three-phase distribution boards and direct circuit protection for heavy industrial loads — a high-capacity MCB widely specified across demanding commercial and industrial switchboards in Australia.

High Capacity, Two Roles

The 50A sits near the top of the HPC2 three-pole range and earns its place on boards where loads are serious. As a main incomer, it protects smaller three-phase distribution boards in commercial and light industrial buildings — a clean, compact alternative where a full MCCB isn't warranted. As a direct equipment breaker, it handles high-draw three-phase loads including large compressors, air handling units, heavy workshop equipment, and industrial process machinery. The thermal-magnetic trip delivers two-stage protection: bi-metal for sustained overloads, magnetic for instantaneous short-circuit response. At 6kA it's rated for fault levels typical in Australian commercial and industrial switchboards.

Termination and Installation

Clips straight onto 35mm DIN rail. The pillar clamp terminal accepts rigid conductors up to 25mm² — no ferrules required. Three modules wide, keeping even high-capacity boards compact. IP20 is appropriate for 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 — one product family for the whole board.

Q: Can the MCB3P50 be used as a main incomer on a three-phase distribution board?
A: Yes — at 50A it is commonly used as the main circuit breaker on smaller three-phase distribution boards in commercial and light industrial buildings. Always confirm incomer sizing against the board's maximum demand, cable ratings, and upstream protection in accordance with AS/NZS 3000.

Q: Is the Tesla MCB3P50 approved for use in Australian switchboards?
A: Yes. The MCB3P50 carries Australian regulatory approval number V08030 and is manufactured to IEC/EN60898. It is suitable for use in compliant Australian switchboard installations.

Q: What conductor sizes does the MCB3P50 accept?
A: The pillar clamp terminal accepts rigid (solid or stranded) copper conductors up to 25mm². Always confirm cable sizing against the circuit load and installation method in accordance with AS/NZS 3000.
