SCHNEIDER ELECTRIC NSX160F LV430631EK ComPact NSX160F Moulded Case Circuit Breaker (MCCB)

Overview The SCHNEIDER ELECTRIC NSX160F (LV430631EK) is a ComPact NSX series fixed 3-pole moulded case circuit breaker with TMD thermal‑magnetic trip unit, frame size 160A, rated current 125A. It is widely stocked as spare parts for low‑voltage distribution panels, motor control centers and power plant auxiliary systems.

Features This NSX160F breaker has Icu=36kA@415VAC breaking capacity. The NSX160F LV430631EK supports adjustable thermal overload setting (87–125A) and fixed magnetic short‑circuit protection. It can be fitted with auxiliary contacts, alarm contacts, shunt trip and undervoltage release accessories. It complies with IEC 60947‑2, and the original LV430631 base model has been discontinued, with replacement part C16F3TM125.

Specs Model: NSX160F, Part No.:LV430631EK Series: Schneider ComPact NSX Type: 3P moulded case circuit breaker Trip unit: TMD thermal‑magnetic In: 125A Frame: 160A Icu: 36kA @415VAC Rated voltage: 690VAC Mounting: Base mount / DIN rail adaptor optional Protection class: IP20 Certifications: CE, IEC, CCC, UL Product status: Obsolete distribution spare

Principle The bimetallic thermal element provides delayed overload protection; the electromagnetic component triggers instant trip under short‑circuit fault. It isolates the faulty circuit automatically to protect cables, transformers and downstream loads.

Applications The NSX160F LV430631EK is widely deployed in industrial MCC panels, pump skids, building distribution cabinets and marine power systems. It is used for overload and short‑circuit protection of AC distribution circuits.
