Siemens JXD62B350 Circuit Breaker – Sentron Series – 350A – 2 Pole – 600VAC – Thermal Magnetic – JD Frame

The Siemens JXD62B350 is a Sentron Series low-voltage molded case circuit breaker designed to provide dependable overload and short-circuit protection for commercial, industrial, and power distribution applications. Rated at 350A and 600VAC, this 2-pole breaker is engineered for single-phase electrical systems requiring high-capacity protection and reliable performance in demanding environments.

Equipped with a thermal-magnetic trip unit featuring Long-Time and Instantaneous (LI) protection functions, the JXD62B350 delivers effective protection against overload conditions and high-level fault currents. Built on the Siemens JD frame platform, this standard 40°C breaker incorporates a non-interchangeable trip unit and standard breaking capacity to ensure consistent operation and equipment protection.

Designed to meet UL 489 and IEC 60947-2 standards, the breaker is supplied without lugs installed, allowing flexibility in selecting compatible terminal connections based on application requirements. Its rugged construction makes it suitable for use in commercial facilities, industrial plants, and power distribution systems operating up to 600VAC.
