Eaton WMZT1C05 - 5A, 48VDC / 277VAC, 1-Pole, Circuit Breaker

The Eaton WMZT1C05 is a compact, single-pole circuit breaker designed to deliver dependable overcurrent protection in both low-voltage DC and standard AC environments. With a 5 A rating and a versatile dual voltage spec, this device is built to simplify protection in mixed-voltage panels without sacrificing reliability.

Why this breaker stands out

• Dual voltage rating: 48 VDC for low-voltage control or battery-backed circuits, and 277 VAC for typical commercial/industrial AC distribution. This makes the WMZT1C05 ideal for mixed-voltage panels where a single protective device can cover multiple circuit types.
• 1-Pole configuration: A streamlined, space-saving design that fits neatly into panelboards, switchboards, and control panels, helping you maximize enclosure real estate in tight installations.
• Precise 5 A protection: Calibrated to interrupt overcurrents at the exact current level you’ve specified, helping guard equipment and wiring from damage while reducing nuisance trips on circuits within its rating.
• Robust applicability: Suited for industrial environments, commercial installations, and OEM applications where safe operation and dependable protection in distribution and motor control centers are essential.

What problems it solves

In panels that host both DC control circuits and AC feeders, managing protection with separate devices can complicate stocking and maintenance. The WMZT1C05 simplifies this by providing reliable 5 A protection across both domains, reducing part counts and increasing install flexibility. It’s particularly beneficial in control panels, panelboards, and switchboards where space is at a premium and reliability is non-negotiable.

Ideal use scenarios

• Controllers and logic circuits that run on 48 VDC in manufacturing lines or automation systems.
• Lighting and auxiliary circuits fed from 277 VAC in commercial spaces.
• OEM equipment enclosures where a single protective device supports multiple circuit types.
• Motor control centers and distribution panels requiring compact, dependable overcurrent protection.
