Eaton WMZS2C40 Two-Pole Miniature Circuit Breaker

The Eaton WMZS2C40 Two-Pole Miniature Circuit Breaker is a two-pole protective device designed to interrupt current on both conductors in electrical panels when an overcurrent occurs. In normal operation it protects connected branch circuits in residential and commercial distribution systems by quickly disconnecting power to prevent wiring damage and reduce fire risk. The WMZS2C40 designation identifies this specific two-pole model within Eaton’s line of miniature circuit breakers, which are used in panelboard installations that require simultaneous pole disconnection. Typical applications include main distribution panels and subpanels where two-pole protection is necessary to safeguard circuits serving outlets, lighting, and equipment.
