It provides a single-phase, 120\/240 VAC, 3-wire service with a 600 A bus and a short-circuit current rating of 65 kA SCCR, suitable for both overhead and underground installations (OH\/UG) in Type 3R enclosures. This main breaker unit serves as the primary protective device within the EZ Meter-Pak assembly, coordinating with the meter center's bus structure to feed downstream circuits. The EZM1600CB is compatible with EZ Meter-Pak configurations and is specified for 600 A service, enabling robust protection for mid-size commercial and multi-tenant electrical distributions. Construction notes indicate aluminum busbar construction for the 600 A main unit, which supports reliable high-current distribution while meeting industrial safety standards. The model is commonly described as a 1 phase, 3 wire main breaker unit, 600 A, 120\/240 VAC, OH\/UG, Type 3R, 65 kA SCCR, from Square D by Schneider Electric. This precise configuration is used when a centralized main protection point is required in a meter-center arrangement, delivering controlled, switchable ingress to feeders while maintaining compliance with applicable electrical codes and utility meter requirements.\u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"New Surplus No Box","offer_id":46259007127786,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-ezm1600cb-main-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
