Eaton PLHT-50-V miniature circuit breaker – 50A high-performance protection with 25 kA
The Eaton PLHT-50-V circuit breaker offers 50 amp protection with a breaking capacity of 25 kA. This makes it one of the most powerful models in the PLHT series. It is therefore designed for industrial main distribution boards and large loads, ensuring reliable protection even for demanding installations.
The tripping characteristic is similar to characteristic curve D. This allows even extreme inrush currents to be tolerated. Consequently, it is suitable for transformers, welding machines, and high-performance industrial motors. Furthermore, it is approved according to IEC/EN 60947-2, the relevant industry standard for low-voltage switchgear and controlgear.
The key advantage lies in the 25 kA breaking capacity. Short-circuit currents can reach enormous levels near power transformers. Furthermore, energy limiting class 3 restricts the energy that can pass through, thus providing optimal protection for downstream devices and lines. Additionally, the 440 V insulation voltage offers a high safety margin.
The Eaton PLHT-50-V miniature circuit breaker (MCB) is 27 mm wide and is designed for DIN rail mounting. It accepts conductor cross-sections from 2.5 to 50 mm² and is compatible with auxiliary devices.
