Eaton WMZT1D01 1A 1-Pole 480 V Circuit Breaker

The Eaton WMZT1D01 1A 1-Pole 480 V Circuit Breaker is engineered to protect single‑phase, high‑voltage circuits with precision and reliability. With a 1 A continuous rating and a 480 V voltage rating, this compact breaker delivers dependable overcurrent protection while fitting neatly into Eaton panels and protection schemes. Part Number: WMZT1D01.

Why this 1-Pole, 480 V breaker stands out

• Exact 1 A rating for sensitive control circuits and low‑load protection, helping prevent nuisance trips on small but critical loads.
• 1‑pole design simplifies installation in single‑phase configurations, reducing panel clutter and simplifying wiring.
• High voltage capability up to 480 V, making it suitable for industrial control panels, equipment enclosures, and other commercial applications.
• Part number clarity—WMZT1D01 ensures fast identification, replacement, and cross‑referencing within Eaton’s ecosystem.
• Durable, dependable operation designed to withstand routine cycling and provide reliable isolation when faults occur.

Ideal use cases

• Control circuits in industrial automation where precise protection of relays, solenoids, and sensors is essential.
• Single‑phase protections within 480 V distribution panels for equipment like pumps, fans, or conveyors with low to moderate current demands.
• Maintenance and replacement scenarios in existing Eaton installations where matching the WMZT1D01 specification ensures compatibility and continuity.

How it fits into your protection strategy

Choosing a lower‑current breaker like the 1 A WMZT1D01 is ideal when the goal is to guard delicate control circuits without impacting normal operational loads. It offers clear advantages over higher‑rating devices in situations where overcurrent events would otherwise damage small components or disrupt essential controls. When your application requires greater protection for higher loads, the Eaton family provides higher amperage and different pole configurations to match your system without compromising reliability.

Practical tips for installation and use

• Verify panel compatibility and ensure a proper 1‑pole, 480 V configuration before installation.
• Consult manufacturer guidelines for torque and mounting procedures to maintain optimal electrical integrity.
• Keep a readily accessible WMZT1D01 spare in service stock to minimize downtime during replacement.
• Document the 1 A rating and 480 V capability in your panel log to assist future maintenance and troubleshooting.

Secure, precise, and purpose‑built for single‑phase protection at high voltage, the Eaton WMZT1D01 1A 1‑Pole 480 V Circuit Breaker is a smart choice for engineers and technicians who demand dependable control‑circuit protection that aligns with existing Eaton infrastructure.
