The Schneider Electric LV434212 is a Zone Selective Interlocking (ZSI) module designed for use with ComPact NSX100 to NSX630 circuit breakers. This module facilitates coordinated tripping within a distribution system, ensuring that only the breaker closest to a fault trips, thereby minimizing power disruption. It is a critical component for enhancing the reliability and selectivity of electrical distribution networks.

Technical details

• Series: ComPact NSX
• Functionality: Zone Selective Interlocking (ZSI) module
• Compatibility: Designed for Schneider Electric ComPact NSX100, NSX160, NSX250, NSX400, and NSX630 circuit breakers.
• Purpose: Enables selective tripping in electrical distribution systems to isolate faults to the nearest upstream breaker.
• Operation: Integrates with the tripping unit of the circuit breaker to receive and transmit interlocking signals.
• Voltage Class: Compatible with systems typically served by the NSX100-630 series, which commonly operate at standard industrial voltages (e.g., 208V, 240V, 400V, 480V, 600V). Specific voltage rating should be verified against the circuit breaker's specifications and the ZSI module's datasheet.
• Current Rating: Applicable to circuit breakers ranging from 100A to 630A.

Applications & compatibility

This ZSI module is essential for industrial facilities, commercial buildings, and data centers requiring precise fault discrimination. It is commonly integrated into main distribution panels, sub-distribution boards, and motor control centers for applications such as manufacturing plants, hospitals, and large office complexes where continuous power availability is paramount.
