• Voltage: 600 V
• Part number: HLXD62B300
• Compatibility note: The HLXD62B300 part number is the best reference for confirming fit with your panel or system.

Key benefits and real-world applications

Designed to protect high-current feeders, the HLXD62B300 provides reliable, twin-leg disconnection to ensure safety and fault containment. Its two-pole architecture means both hot legs trip together, helping to prevent arcing and equipment damage in the event of an overload or short circuit. This makes it a dependable choice for industrial panels, commercial service equipment, and retrofit projects where maintaining system integrity is essential.

Ideal use cases

• Maintenance: replace aging or failed breakers in existing Siemens installations with a like-for-like spec.
• Retrofit: upgrade protection for updated loads or reconfigured circuits without compromising safety or compatibility.
• Replacement: straightforward swap-in for panels that require a 300 A, 2-Pole, 600 V protection device.

Practical guidance for selection

Before ordering, confirm fit and ratings to avoid compatibility issues. Rely on the HLXD62B300 part number as your primary reference to match panel catalogs and labeling. When planning a upgrade or replacement, evaluate the current and anticipated load on the circuit to ensure 300 A protection aligns with your system’s design and safety requirements.
