Key specifications

• Current rating: 10 A
• Poles: 3
• Voltage rating: 480 V
• Part number: WMZT3C10

What makes it unique

• Three-pole design specifically addresses 3-phase systems, allowing simultaneous disconnection of all live conductors for safer maintenance and rapid fault isolation.
• Optimized for 480 V service, ensuring compatibility with common industrial motor drives and distribution networks without oversizing protection.
• Durable Eaton construction delivers dependable tripping performance and long-term reliability in demanding environments where uptime matters.

Ideal use cases

• Protection for motors, conveyors, pumps, and HVAC equipment in warehouses, manufacturing floors, and data centers powered by 480 V three-phase service.
• New installations or panel upgrades where a compact, reliable 3-pole breaker is required to meet electrical codes and safety standards.
• Retrofits and service replacements that need a known, compatible WMZ-series breaker with a fixed 10 A rating.

Installation and compatibility

• Designed for Eaton panels that accept WMZ-type breakers; verify panel compatibility before installation.
• Follow standard electrical practices for mounting, wiring, and torque specifications to ensure a secure, code-compliant connection.

Practical tips and maintenance

• Keep a record of the WMZT3C10 part number for future service, spares, or panel expansions to streamline maintenance planning.
• Perform routine inspections for signs of wear, overheating, or corrosion, and replace if performance is degraded to preserve system protection.
• In systems with frequent motor starts or high inrush currents, confirm that a 10 A rating remains appropriate for protecting downstream conductors and loads.
