Industrial WMZS1C40 40A 1-Pole 480 V Circuit Breaker

Industrial WMZS1C40 40A 1-Pole 480 V Circuit Breaker — a compact, dependable overcurrent protection device built for demanding industrial environments. With a 40 A rating, a single pole, and a 480 V operating capacity, this breaker is purpose-built to safeguard individual hot-line circuits in distribution boards, control cabinets, and machine feeders. Part number WMZS1C40 is your clear, stockable identifier for quick replacements and service calls.

Key benefits that matter in practice

• Precise 40 A protection for single-leg circuits in 480 V systems, helping prevent wiring damage and equipment failures.
• 1-Pole design simplifies integration into dedicated hot-conductor circuits within compact industrial panels.
• Rugged, industrial-grade construction built to perform in busy plant environments where reliability is non-negotiable.
• Clear identification of the part number WMZS1C40 streamlines stocking, maintenance planning, and field replacements.
• Straightforward replacement path—designed to slot into existing panel architectures with minimal adjustments, reducing downtime during maintenance or upgrades.

Ideal use cases

• Protection for individual feeders and control circuits inside panelboards and distribution boards in manufacturing facilities.
• Spare parts for industrial maintenance programs, ensuring quick, on-shelf availability when a circuit needs protection restored.
• Retrofit projects where a dedicated 480 V, 1-pole protection device is required for a single hot conductor.

Why this model stands out

The Industrial WMZS1C40 40A 1-Pole 480 V Circuit Breaker delivers targeted overcurrent protection without complicating your panel design. Its single-pole format is ideal for scenarios where only one leg needs protection, while its 480 V rating aligns with higher-voltage distribution schemes common in industrial settings. By choosing the WMZS1C40, you gain a reliable, easy-to-identify component that supports efficient maintenance workflows and reduces the risk of unplanned downtime.

How it works

When current on the protected line exceeds the 40 A rating, the device trips to interrupt the circuit, shielding wiring and connected equipment from damage. This action helps preserve circuitry integrity and supports safer, more predictable operation of your industrial systems.
