Siemens JXD22B225 - 225 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens JXD22B225 — a robust 225 A, 240 V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection for panelboards and load centers. Built to withstand demanding environments, it pairs precise protection with a secure, vibration-resistant connection that keeps your electrical system aligned and Australian with Siemens OEM equipment.

Powerful, precise protection you can count on

• Secure bolt-on mounting: a rigid, vibration-resistant bus connection that stays solid under heavy loads and in spaces prone to movement.
• Thermal-magnetic trip unit: delivers stable, repeatable protection against overcurrent and short circuits, reducing nuisance trips and enhancing reliability.
• High-capacity, 2-pole design: 225 A at 240 V, ideal for protecting large feeders and critical branch circuits in residential, commercial, and light industrial applications.
• OEM compatibility: specifically designed to fit matching Siemens load centers and panelboards, ensuring proper fit and electrical coordination.
• Versatile application range: suitable for a variety of settings—from home electrical upgrades to small business panels—where strong protection and durable construction matter.

Why this breaker matters in your panel

When you’re managing a busy electrical system, reliability matters. The JXD22B225 combines a high-amperage rating with a rugged bolt-on installation to reduce installation time and maintenance issues, while the thermal-magnetic trip mechanism provides immediate response to faults. The result is faster fault clearing, safer operation, and fewer disruptions for sensitive equipment and busy spaces.

Use cases and ideal installations

• Upgrading residential or commercial panelboards to support larger feeders and higher-demand circuits.
• Replacing aging or incompatible breakers in Siemens panels to maintain proper coordination and protection levels.
• Feeding critical loads such as large appliances, HVAC equipment, or lights in light industrial settings where dependable protection is essential.
