Square D | SDT225 | Circuit Breaker | 25A | 2-Pole | 240V | Plug-In

Square D SDT225 is a 25-amp, 2-pole, 240-volt plug-in circuit breaker designed to keep electrical systems safe and running smoothly during maintenance, retrofit, or replacement projects. Built to meet standard Square D specifications, this breaker slides into compatible panels for a secure, quick-change solution.

Key specifications

• Amperage: 25 A
• Poles: 2-Pole
• Voltage: 240 V
• Mounting: Plug-In
• Part reference: SDT225

When planning a replacement, the exact part number is your best reference for compatibility. The SDT225 is specifically intended for installations where 25A, 2-pole protection at 240V is required, and where a plug-in style breaker is supported by the panel design.

Why this matters

• Fast, tool-friendly swap reduces service downtime in electrical panels that support plug-in breakers.
• Accurate amperage rating ensures the protected circuit stays within safe operating limits for connected loads.
• A single, well-documented part number (SDT225) simplifies ordering and reduces confusion during maintenance or retrofit projects.

Ideal for

• Maintenance and replacement of 240V circuits in compatible Square D panels.
• Retrofits that require exact 25A, 2-pole, plug-in protection to maintain panel labeling and code compliance.
• Small to mid-size residential or commercial electrical setups where a 25A 240V circuit is needed.

Practical guidance

Always confirm fit and ratings before ordering. Use the SDT225 part number as the primary compatibility reference, and verify that your panel supports a plug-in breaker of this amperage and configuration. If in doubt, consult your panel’s documentation or a qualified electrician to ensure proper installation and safe electrical practice.
