CHINT 63A 4-Pole MCB (Miniature Circuit Breaker) is a reliable low-voltage protection device designed for three-phase electrical systems (3-phase + neutral). It automatically trips during overload or short circuit conditions, protecting cables, equipment, and distribution panels.
Rated at 63 Amps with a typical operating voltage of 380–415V, it features 4-pole protection, ensuring complete isolation of all phases and neutral for enhanced safety. It is commonly used in industrial installations, commercial buildings, and distribution boards, and is designed for easy mounting on a DIN rail. 
Key advantages: durable construction, fast tripping response, high breaking capacity (around 6kA), and dependable performance in heavy-load applications.
