• Single-pole protection in 480V systems — Designed for scenarios where a single phase of a 480V circuit requires reliable interruption and protection, helping safeguard motors, controls, and feeders in industrial environments.
• Industrial-grade reliability — Built to operate in the demanding conditions of manufacturing floors and service workshops, providing consistent performance when it matters most.
• Clear reference for compatibility — The product description emphasizes using the part number as the best compatibility reference, helping you verify fit quickly and avoid downtime.

Use cases and practical scenarios

• Replacing a failed breaker in a 480V control panel or motor control center (MCC) where a 20A, 1-Pole unit is required.
• Retrofits that introduce updated protection without reconfiguring the entire electrical rack.
• Maintained spare on hand for scheduled maintenance windows or emergency swap-outs, reducing equipment downtime.
• New installations where a compact, single-pole 480V breaker is needed to isolate a dedicated circuit safely.

Important note: before ordering, confirm fit and ratings for your specific application. Use the WMZS1C20 part number as the primary compatibility reference to ensure the breaker matches your panel and system requirements.
