Square D DD-25 - 3-Pole, Circuit Breaker

Square D DD-25, a 3-Pole Circuit Breaker, delivers dependable overcurrent protection in demanding electrical systems. The 3-pole configuration provides robust three-phase protection that fits seamlessly into panelboards, switchboards, and control panels.

Designed for industrial, commercial, and OEM environments, the DD-25 helps keep critical equipment—like motors and control circuits—safe from overloads and short circuits. Its single-device approach protects all three phases, reducing wiring complexity and saving panel space while maintaining precise protection coordination.

• Three-pole, three-phase protection: consolidates protection across all phases, simplifying protection schemes in motor control centers.
• Durable, purpose-built construction: engineered to withstand the rigors of distribution panels and control centers in tough environments.
• Versatile installation: suitable for panelboards, switchboards, and control panels across industrial, commercial, and OEM applications.
• Streamlined maintenance: common interface with Square D components for easier replacement and service in existing systems.
• Space- and wiring-efficient: one device handling three lines reduces panel clutter and simplifies wiring runs.

Ideal for: facilities with three-phase machinery (pumps, conveyors, HVAC, CNC equipment), OEM equipment integrators needing reliable, compact protection, and maintenance teams seeking predictable, easy-to-troubleshoot protection devices.

Practical tips for use: verify panel compatibility and mounting fit within your Square D distribution system; plan protection coordination with upstream/downstream devices to avoid nuisance trips; schedule periodic functional tests per maintenance protocols to confirm trip reliability.

With the Square D DD-25, you gain sturdy, dependable protection for critical three-phase circuits—keeping distribution panels and motor control centers up and running when it matters most.
