Eaton WMZT3D15 3-Pole D-Curve 15A DIN-Rail Miniature Circuit Breaker Thermal-Magnetic UL 489 Branch Circuit Protection for Industrial Panels

The Eaton WMZT3D15 is a 3-pole, 15 A D-curve miniature circuit breaker engineered for dependable branch-circuit protection in industrial control panels and machinery. It provides thermal-magnetic overcurrent response and fast current-limiting performance for safer, more efficient system operation.

Why It Helps

The WMZT3D15 is built to manage demanding loads with high inrush current, preventing nuisance trips in motor-driven and inductive applications. Its UL 489 listing ensures compliance for branch-circuit protection, while the D-curve characteristic supports heavy starts without compromising safety. DIN-rail mounting, robust terminals, and a clear trip indicator simplify installation, integration, and maintenance.

Key Highlights

• D-curve thermal-magnetic protection provides reliable overload and short-circuit response, ideal for motors, transformers, and high-inrush equipment.
• UL 489 compliance ensures the breaker meets strict requirements for branch-circuit protection in industrial and commercial installations.
• Current-limiting design minimizes let-through energy, helping protect connected equipment during fault conditions.
• Standard DIN-rail mounting and open-mouth/lift terminals support quick, secure installation in control panels and distribution assemblies.
• Integrated trip indicator provides immediate visual confirmation of breaker status to streamline troubleshooting.

Applications
The WMZT3D15 is suited for industrial branch circuits, motor control centers, HVAC/R systems, PLC I/O protection, power supplies, instrumentation, and general control equipment. Its robust design, UL listing, and high-performance D-curve characteristics provide long-term reliability in demanding electrical environments.
