Industrial WMZS2D01 1A 2-Pole 277 V Circuit Breaker

Meet the WMZS2D01 Industrial 1A 2-Pole 277 V Circuit Breaker — a precise, dependable protective device designed to guard your low-current circuits in demanding industrial environments. This two-pole breaker interrupts both hot legs, delivering robust overcurrent protection for 277 V systems while simplifying wiring and panel organization.

Key specifications

• Current rating: 1 A
• Poles: 2
• Voltage rating: 277 V
• Part number: WMZS2D01

Why this matters

The 2-pole configuration ensures simultaneous disconnection of both conductors in the protected circuit, reducing the risk of backfeed and improving safety for multi-wire branch circuits common in commercial lighting and control panels. With a 277 V rating, this breaker is well-suited for lighting distribution, HVAC controls, and other equipment fed from 277 V systems in industrial settings.

Ideal use cases

• Commercial and light-industrial lighting circuits operating at 277 V
• Small control panels and instrumentation circuits needing reliable, targeted protection
• Feeder protection for multi-wire branch circuits in panelboards and switchgear

Installation and compatibility tips

Ensure your electrical panel accepts a 2-pole 277 V device of this style. Verify conductor sizing and follow local codes and manufacturer installation guidelines for secure connections. Clearly label the circuit to reflect its protection purpose, and maintain a stock of replacement breakers for quick maintenance in busy industrial facilities.
