LV429674

Schneider Electric's LV429674, a part of the ComPact series, is a molded case circuit breaker (MCCB) designed for reliable operation in various electrical applications. With a mechanical lifespan of 50,000 cycles, it ensures durability and longevity in use. The electrical operating life of this device can reach up to 30,000 cycles, although this may vary based on the application.

This MCCB is equipped with both overload protection functions (L) and short-circuit protection (I) to safeguard circuits against faults. It features a maximum breaking capacity (Icu) of up to 100 kA when functioning at 240 V AC, providing substantial protection against electrical surges. The device is designed with three poles and has a current rating of 40 A, suitable for operations at a temperature of 40 °C.

The voltage rating for operational use reaches 690 V AC and supports 50/60 Hz frequencies. It maintains an insulation voltage of 800 V AC and can withstand impulse voltage ratings of up to 8 kV. The circuit breaker utilizes a fixed backplate mount configuration, and the terminal orientation is positioned at the front for convenient access.

Employing a thermal-magnetic tripping mechanism (TM-D trip unit), this MCCB offers adjustable thermal trip settings to accommodate current ranges from 28 A to 40 A (0.7–1 × In). Furthermore, it has a service breaking capacity (Ics) that can also accommodate up to 100 kA at 240 V AC, ensuring comprehensive protection for electrical systems.
