Eaton WMZH3D16T 3-Pole 16A Type D UL 489 High-Interrupting DIN-Rail Breaker D-Curve Thermal-Magnetic Protection for High-Inrush Industrial Loads

Eaton WMZH3D16T Miniature Circuit Breaker

The Eaton WMZH3D16T is a high-performance 3-pole, 16-amp DIN-rail mounted miniature circuit breaker engineered for dependable branch circuit protection. Built on the WMZ series platform, it delivers proven reliability and robust thermal-magnetic operation for industrial and commercial equipment.

Why It Helps
Its D-curve tripping profile supports loads with high inrush current, such as motors and power supplies, ensuring stable operation without nuisance tripping. The breaker’s current-limiting design reduces let-through energy, helping protect connected devices and downstream wiring. UL 489 listing and a 14 kA interrupting capacity further enhance protection in demanding environments.

Key Highlights
• The 14 kA interrupting rating provides strong fault-clearing capability for industrial branch circuits, supporting safe operation in high-energy environments.
• DIN-rail mounting allows fast panel integration, while captive screws and clear status indicators streamline installation and maintenance.
• Thermal-magnetic protection ensures reliable response to both overloads and short-circuit events, offering balanced protection for inductive loads with high inrush.
• Trip-free design ensures the breaker cannot be forced closed, supporting safe operation and code compliance in critical installations.

Applications
Suitable for branch circuit protection in equipment such as motor controls, HVAC systems, PLC I/O panels, computers, instrumentation, relays, UPS systems, and power conditioners. Its D-curve characteristics and current-limiting design provide durable and dependable performance in installations requiring high-inrush tolerance.
