Schneider LV430470 ComPacT NSX Trip Unit 3P 160 A MicroLogic 2

The Schneider Electric LV430470 is an electronic MicroLogic 2.2 trip unit designed for ComPact NSX 160/250 circuit breakers, providing LSoI protection (overload, short-time short-circuit, and instantaneous short-circuit) for distribution applications. Rated at 160 A and compatible with 3-pole ComPact NSX160 and NSX250 frames, it offers adjustable long-time and short-time protection settings. Note: this product was discontinued on 15 June 2023.

Features and benefits:

• Electronic LSoI protection covers long-time overload, short-time short-circuit with fixed delay, and instantaneous short-circuit in a single unit
• 9-position adjustable long-time pick-up (Ir) from 63 to 160 A allows precise calibration to load requirements
• Built-in thermal memory retains thermal state for 20 minutes, preventing nuisance re-closing after a thermal trip
• Three-colour LED local signalling provides clear at-a-glance status: ready, overload warning, and overload alarm
• Wide operating temperature range of -25 to 70 °C suits demanding industrial environments
• Certified to Marine, EAC, and CCC standards in addition to UL 508 and EN/IEC 60947-2

Applications:

• Main and sub-distribution boards in commercial and industrial installations requiring coordinated protection
• Feeder protection in power distribution panels using ComPact NSX160 or NSX250 circuit breaker frames
• Industrial control panels and switchgear assemblies demanding adjustable electronic overcurrent protection
• Marine and offshore electrical systems requiring certified trip units for harsh environment compliance

Compliant with UL 508 and EN/IEC 60947-2. Part of the Schneider Electric ComPact NSX range.
