Industrial WMZS1C15 15A 1-Pole 277 V Circuit Breaker

Meet the Industrial WMZS1C15 15A 1-Pole 277 V Circuit Breaker — a purpose-built protective device designed for commercial and industrial electrical systems that demand reliability and straightforward protection of critical circuits. With a 15-amp current rating, a single protective pole, and a 277-volt operating capability, this breaker is tailored for environments where steady performance matters.

Key specifications and identity

• Part Number: WMZS1C15
• Current rating: 15 A
• Poles: 1
• Voltage rating: 277 V

Why this design matters

In many commercial and industrial settings, 277 V is the standard for lighting and control circuits. A single-pole breaker protects just the affected conductor, helping contain faults without unnecessarily interrupting other feeders. Built for industrial use, this unit is designed to hold up under regular equipment cycling, vibration, and the temperature ranges found in busy facilities.

Practical applications

• 277 V lighting circuits in warehouses, manufacturing floors, and large office complexes
• Dedicated protection for branch circuits feeding equipment or control devices
• Replacement or upgrade in panels that already support the WMZS1C15 family

Installation and maintenance tips

Ensure your panel accepts single-pole, 277 V breakers and that the mounting and bus connections are compatible with the WMZS1C15 line. When installing, apply the manufacturer’s torque specs to the terminals to maintain solid, low-resistance connections. Periodically inspect for signs of overheating, corrosion, or tripped states, and replace the device if any concerns arise.

Why choose the WMZS1C15? It delivers dependable overcurrent protection for mid-load, 277 V circuits with a straightforward form factor that simplifies replacement and maintenance in demanding environments. If you’re outfitting an industrial control panel, lighting distribution, or a commercial electrical system that runs at 277 V, this 15 A, 1-Pole breaker offers a clear, no-surprises protection path.
