Siemens | JXD62L400 | Circuit Breaker | 400A | 2-Pole | 600V | Bolt-On

Meet the Siemens JXD62L400 Circuit Breaker — a robust 400A, 2-pole, 600V bolt-on protection device engineered for reliability in demanding electrical systems. Designed for maintenance, retrofit, and replacement projects, it slips into Siemens-compatible panels with precision and confidence.

• Amperage: 400 A
• Poles: 2-Pole
• Voltage rating: 600 V
• Mounting: Bolt-On for secure mechanical contact and stable operation

The JXD62L400 is built to withstand the rigors of continuous operation in industrial environments. Its bolt-on design provides a solid, vibration-resistant connection that helps maintain consistent electrical performance even in demanding conditions. This makes it a dependable choice for panel upgrades, equipment modernization, or safeguarding critical loads in commercial facilities.

Ideal use cases

Best-suited for:

• Retrofits and replacements in Siemens panel systems that require 400A, 2-pole protection up to 600V
• Upgrading service ratings in industrial electrical distribution to support higher-capacity feeders
• Maintenance planning where compatible JXD62L400 parts are specified as the reference

Why this matters: choosing the exact part number JXD62L400 ensures compatibility with existing Siemens bus assemblies and trip schemes. Confirm fit and ratings before ordering—the part number is the most reliable reference for a precise match.

Practical notes and best practices

• Always match the circuit breaker's amperage, number of poles, and voltage rating to the panel's specifications.
• Use as part of a planned retrofit or replacement strategy to minimize panel downtime.
• Follow standard electrical safety procedures and torque guidelines for bolt-on mounting as specified by your panel manufacturer.

What you gain

With the Siemens JXD62L400, you gain a trusted, high-performance protection device designed to reliably interrupt overcurrent events and protect downstream equipment. Its 400A capacity supports robust distribution for feeders and large loads, while the 2-pole configuration provides comprehensive phase protection.
