Siemens HHED63B050 - 50 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens HHED63B050 represents a dependable, stage-ready solution for protecting your electrical distribution. This 50A, 600V, 3-pole bolt-on molded case circuit breaker is engineered to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers, keeping critical systems powered with minimal interruptions.

• Bolt-on mounting ensures a rigid, vibration-resistant bus connection. The secure attachment minimizes movement within the panel, supporting consistent performance in environments where panels endure vibration or movement.
• Thermal-magnetic trip unit combines precise overload protection with instantaneous short-circuit action. This means predictable, repeatable trips under fault conditions and stable operation across temperature fluctuations.
• Three-pole design is ideal for balanced 3-phase circuits, providing coordinated protection for motors, lighting, and other commercial or light industrial loads.
• OEM panel compatibility ensures seamless integration with matching Siemens load centers and panelboards, simplifying replacement or upgrades without compromising fit or trip characteristics.
• Versatile application suitable for residential, commercial, and light industrial settings, making it a practical choice for new installations or panel retrofits that require robust, space-efficient protection.
