Schneider Electric | LV434563 | Circuit Breaker | 160A | 4-Pole

Schneider Electric LV434563 is a 160A, 4-pole circuit breaker designed for reliability in industrial and commercial electrical distributions. Built to support maintenance, retrofit, and replacement projects where exact specifications matter, this unit provides a clear path to restore or upgrade your panel's protection with Schneider Electric's trusted performance.

• Amperage: 160A
• Poles: 4-Pole
• Part number: LV434563
• Best compatibility reference: Use the LV434563 part number to confirm fit and ratings prior to ordering

What problems does it solve?

With a 4-pole configuration, this breaker provides simultaneous disconnection of all current-carrying conductors in 3-phase systems with an embedded neutral, helping to reduce switching errors during maintenance and ensuring safer shutdowns. The 160A rating protects circuits feeding moderate-to-high load equipment, such as motors, pumps, and commercial lighting systems.

Ideal for — who should use this?

• Facilities managers performing panel upgrades or replacements in commercial or light industrial settings
• Electrical contractors replacing worn breakers in Schneider Electric ecosystems to maintain consistent performance
• OEM applications building or retrofitting panels that require a precise LV434563 4-pole protector

Practical use cases

• Maintaining reliability in a data center rack or server room where a 3-phase supply includes a neutral
• Retrofit projects upgrading legacy panels to modern 4-pole protection to meet current safety standards
• Replacement of failed 4-pole breakers in industrial machinery control panels

Installation and safety tips

Always verify that the host panel’s ratings and busbar design match the LV434563 specifications. Before installation, confirm fit using the part number LV434563 as the primary compatibility reference. Follow standard electrical safety procedures and the panel manufacturer’s torque and wiring guidelines to ensure secure connection and reliable operation.

Why this design stands out

Choosing a Schneider Electric LV434563 4-pole breaker means compatibility with Schneider panels and a consistent performance profile you can rely on across maintenance and retrofit cycles. The 4-pole format simplifies control logic by providing independent disconnection for all conductors, which is especially valuable during service work on three-phase systems with neutral.
