Product Description

The KT28-63P circuit breaker is a high-performance 63A MCB designed for efficient overcurrent and short-circuit protection in low-voltage electrical systems. This KT28-63P miniature breaker supports single-phase or three-phase configurations, directly accommodating up to 3 poles in a compact modular design. It operates within a voltage range of 230V AC to 440V AC and functions reliably across a temperature spectrum of -25°C to +60°C, making it suitable for industrial, commercial, and residential applications. The device features a rugged thermoplastic housing with a 6kA breaking capacity, ensuring durability and safety. While it lacks integrated communication interfaces, its streamlined design simplifies installation in standard DIN rail enclosures. Notable advantages include rapid trip response, low energy loss, and compatibility with auxiliary accessories like shunt releases. However, it does not support advanced remote monitoring functionalities. The KT28-63P is widely utilized in distribution panels, machinery control, and building electrical networks for its cost-effectiveness and compliance with IEC 60898 standards.
