This compact and cost-effective device provides reliable overload and short-circuit protection for all live conductors in three-phase four-wire systems. Designed for feeder and distribution protection in commercial and industrial applications, it offers a practical solution where complete circuit isolation and neutral protection are required.

The Schneider Electric EZD 4P 400A is a 4-pole (3-phase + neutral), 400A molded case circuit breaker from the EZD series. As a compact and cost-effective solution, it provides reliable overload and short-circuit protection for all live conductors in three-phase four-wire systems.

The Schneider Electric Acti 9 iC65N 3P 40A 300mA is a 3-pole, 40A, 300mA Residual Current Circuit Breaker with Overcurrent Protection (RCBO). This integrated device combines a miniature circuit breaker (MCB) and an earth leakage protector (RCD) into one unit, specifically designed for three-phase circuits requiring protection against overloads, short circuits, and earth leakage currents, but with a higher residual current setting for equipment/fire protection rather than personal shock protection.

The Schneider Electric Compact NSX 4P 100N 80A is a 4-pole (3-phase + neutral), 80A molded case circuit breaker from the premium Compact NSX series. The "100N" designation indicates it is built on the 100A frame and is equipped with a standard thermal-magnetic (N) trip unit. It provides reliable and cost-effective overload and short-circuit protection for all live conductors in three-phase four-wire systems where neutral isolation and protection are required.

The Schneider Electric Masterpact NSX 800N 800A is an 800A, N-frame Air Circuit Breaker (ACB) from the premium Masterpact NSX series (not to be confused with the smaller "Compact NSX" MCCB range). This device is designed for main power distribution and protection in large commercial buildings, industrial plants, and critical infrastructure. The "N" typically indicates a standard thermal-magnetic or basic electronic trip unit version.

The Schneider Electric Acti 9 iST 3P+N 65kA is a Type 2 (Class II) Surge Protective Device from the iST series. It provides robust surge protection for three-phase systems with its 3P+N configuration and a very high 65kA nominal discharge current per mode. This model is engineered for high-risk or demanding applications where high surge current capacity and reliability are paramount.

The Schneider Electric Acti 9 iST 3P+N 40kA is a Type 2 (Class II) Surge Protective Device from the iST series. Its 3P+N configuration provides comprehensive protection for all live conductors in three-phase electrical systems.

The Schneider Electric Acti 9 iST 3P+N 20kA is a Type 2 (Class II) Surge Protective Device from the iST series. Its 3P+N configuration provides comprehensive protection for all live conductors in three-phase electrical systems

The Schneider Electric EZ7A26420G 4P 20A is a 4-pole, 20A circuit breaker from the EasyPact series (likely the EZ7 or EZ9 series, often marketed as EasyPact EZC or similar). This compact device is designed for distribution and protection in three-phase four-wire electrical installations, such as small commercial or residential systems. The code "G" may indicate a specific curve type or accessory configuration.

The Schneider Electric Masterpact MTZ2-32H1 is a high-end, intelligent Air Circuit Breaker (ACB) from the Masterpact MTZ series. This model represents a specific configuration within the "MTZ2" frame size (3200A) range, with the "H1" suffix indicating a particular combination of rated current, breaking capacity, and fixed/draw-out version. It is designed for advanced protection, control, and energy management in critical power distribution systems of large commercial buildings, industrial plants, and data centers.

The Schneider Electric Compact NSX630L 3P 500A is a 3-pole, 500A molded case circuit breaker (MCCB) from the premium Compact NSX series. The "L" suffix designates a specific high breaking capacity variant (typically 150kA). This high-performance device is engineered for main distribution and critical feeder protection in industrial and infrastructure applications where very high fault currents are present, requiring superior interrupting capability and reliability.
