The 3-Phase Over Current Relay (A30C-111) is a highly reliable and efficient protection device designed to safeguard electrical systems, motors, transformers, and industrial equipment from damage caused by excessive current flow. Built for precision and durability, this relay plays a critical role in detecting abnormal current conditions and triggering protective actions before serious faults occur.
⚙️ Advanced Protection Mechanism
The A30C-111 relay continuously monitors the current flowing through all three phases of an electrical system. When the current exceeds a preset threshold due to overload, short circuit, or fault conditions, the relay quickly responds by sending a trip signal to the circuit breaker. This ensures immediate isolation of the faulty circuit, minimizing equipment damage and preventing potential hazards such as overheating or fire.
🔧 Robust Design & Construction
Engineered with high-quality components, the relay offers excellent durability and long service life even in demanding industrial environments. Its compact design allows easy panel mounting, making it suitable for both new installations and retrofit projects. The sturdy enclosure protects internal circuitry from dust, vibration, and temperature variations.
