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.

The Schneider Electric Acti 9 iC65 4P 40A 30mA is a 4-pole (3-phase + neutral), 40A, 30mA Residual Current Circuit Breaker with Overcurrent Protection (RCBO). This integrated device combines a high-performance miniature circuit breaker (MCB) and a sensitive earth leakage protector (RCD) into a single compact unit.

The Schneider Electric C4035A400 is a model designation within the PowerLogic™ Series 800 or related Power Meter family. This specific code likely refers to a multi-function power meter designed for 400A direct input applications.

The Schneider Electric Acti 9 iPRF1 3P 12.5R is a Type 1 (Class I) Surge Protective Device from the iPRF1 series, featuring a 3-pole configuration and a built-in thermal disconnector ("R" version). It is designed to provide primary protection at the service entrance of three-phase electrical systems against direct and partial direct lightning strikes (10/350µs waveform).

The Schneider Electric Compact NSX100F 50A 4P 3D is a specialized 4-pole, 50A, fixed-type molded case circuit breaker (MCCB) from the Compact NSX series. The unique "3D" configuration indicates a 3-pole protected + 1 switched neutral design, providing a specific and cost-optimized solution for three-phase systems where the neutral conductor requires switching but not necessarily overcurrent protection.

Schneider Electric Smart SPDs are advanced Surge Protective Devices equipped with intelligent monitoring and communication capabilities. Primarily represented by the iPV series for photovoltaic systems and the iSTU series for building/industrial AC systems, they go beyond basic surge clamping by providing real-time status data, remote alarms, and integration into energy management systems for predictive maintenance and enhanced system reliability.

The Schneider Electric PRD 80R 3P is a Type 2 (Class II) Surge Protective Device from the Easy9 / PowerPact PDU series. The "R" version indicates it has a built-in thermal disconnector, eliminating the need for an external backup fuse in standard applications.

The Schneider Electric EZD400M 4P 350A is a 4-pole (3-phase + neutral), 350A, M-frame molded case circuit breaker from the EZD series. This compact and economical device provides reliable overload and short-circuit protection for three-phase four-wire systems, where protection and isolation of the neutral conductor are required.
