The Schneider Electric Compact NSX series 4-pole (3P+N) molded case circuit breakers in 100A and 160A ratings represent the premium tier of compact MCCBs. Designed for main and sub-distribution protection in three-phase four-wire systems, they provide superior performance, reliability, and flexibility for commercial, industrial, and infrastructure applications where neutral protection or complete circuit isolation is required.

The Schneider Electric Acti 9 iCNV 4P 40A 230V is a 4-pole, 40-ampere, 230-volt Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from the iCNV series. This integrated protection device combines miniature circuit breaker (MCB) functions and earth leakage protection (RCD) in a single compact unit, designed specifically for final circuit protection in single-phase three-wire or certain three-phase systems where a 230V line-to-neutral voltage is applied.

The Schneider Electric WATSNB-160/160-3CBR is a 3-pole, 160A Automatic Transfer Switch (ATS) featuring Closed Transition (Parallel) operation. Designed for critical power applications, it provides seamless and uninterrupted transfer between two independent 160A power sources, typically a Main (Utility) supply and a Backup (Generator) supply.

The Schneider Electric Acti 9 iPRU 4P 20R is a Type 2 (Class II) Surge Protective Device designed for the main distribution board in three-phase electrical systems. The "20R" suffix indicates it is a special version with a built-in thermal disconnector, making it a "plug-and-play" SPD that does not require an external backup fuse or circuit breaker for most applications. It provides protection against transient overvoltages from indirect lightning strikes and switching surges.

The Schneider Electric Acti 9 iC65 Vigi iC65 ELE 4P 40A 30mA is a 4-pole (3P+N), 40A, 30mA Residual Current Circuit Breaker with Overcurrent Protection (RCBO). It integrates a high-performance MCB (iC65) and a sensitive earth leakage protection module (Vigi iC65 ELE) into one compact device, providing comprehensive protection for three-phase circuits against overloads, short circuits, and earth fault currents.

The Schneider Electric WATSN32/4AVK is a 4-pole (3P+N), 32A Automatic Transfer Switch (ATS) from the WATS series. It is designed for reliable, automatic transfer of power between two independent sources (typically Main and Generator) in critical single-phase or three-phase applications. The "AVK" suffix indicates specific features related to its control logic and operation.

The Schneider Electric NSX100F 3P 25A is a 3-pole, 25A, fixed-type molded case circuit breaker (MCCB) from the premium Compact NSX series. This compact yet high-performance device provides superior overload and short-circuit protection for three-phase circuits in commercial, industrial, and infrastructure applications where reliability, precision, and durability are essential.

The Schneider Electric EZD 4P 200A is a 4-pole (3-phase + neutral), 200A molded case circuit breaker from the EZD compact series. It provides comprehensive protection for four-wire electrical systems, safeguarding against overloads and short circuits on all live conductors. This cost-effective and reliable solution is designed for commercial and industrial distribution applications where neutral protection or full circuit isolation is required.

The Schneider Electric EZD400M 3P 320A is a 3-pole, 320A, M-frame molded case circuit breaker (MCCB) from the EZD series. This cost-effective and compact device provides reliable overload and short-circuit protection for three-phase power distribution circuits in commercial and industrial applications. The "M" frame size (400A maximum) with a 320A trip unit setting offers a balance of performance and economy for feeder protection.

The Schneider Electric NSX400/630 3P refers to a 3-pole circuit breaker from the Compact NSX series, spanning two frame sizes: the 400A frame (NSX400) and the 630A frame (NSX630). These are high-performance molded case circuit breakers (MCCBs), often categorized as compact air circuit breakers due to their advanced features and higher current range. They are designed for main distribution and critical feeder protection in industrial, commercial, and infrastructure applications.
