Eaton WMZT3C10T 10A 3-Pole 480 V Circuit Breaker

The Eaton WMZT3C10T 10A 3-Pole 480 V Circuit Breaker is a dedicated three-phase protection device designed for reliable overcurrent control in demanding 480V systems. With a 10 A rating and three poles, this part (WMZT3C10T) ensures synchronized disconnection across all phases to safeguard equipment, panels, and personnel in industrial environments.

Why a 3-pole design matters

In three-phase networks, protecting every phase together minimizes the risk of phase imbalances and catastrophic faults. The WMZT3C10T delivers coordinated tripping across all three lines, helping prevent damage to motors, drives, and downstream circuits when overloads or faults occur.

Key specifications

• Current rating: 10 A
• Poles: 3
• Voltage rating: 480 V
• Part number: WMZT3C10T

Ideal applications

Perfect for industrial control panels, distribution boards, and 3-phase equipment fed from 480V systems. Use cases include protecting branch circuits for motors, conveyors, pumps, and other three-phase machinery where balanced phase protection is essential and load currents stay within the 10 A range.

What makes this Eaton breaker stand out

• Directly addresses safety and reliability in 3-phase, 480V installations by ensuring all phases trip together.
• Simple, straightforward replacement for compatible Eaton panel configurations requiring a 3-pole, 10 A device.
• Clear, unambiguous labeling with the WMZT3C10T designation supports quick identification during maintenance and inspections.

Practical tips for installation and use

Before installation, confirm that your protected circuit operates within the 10 A limit and that your wiring and insulation are rated for up to 480 V. Plan for periodic inspection of the breaker for signs of wear or overheating, and follow your facility’s maintenance schedule to test trip functionality under controlled conditions.
