Circuit breaker LZM1, 3-pole Ir=63-80A LZMC1-A80-I 111894

Power circuit breaker – reliable protection for electrical installations

The LZM1 power circuit breaker is a three-pole device designed to protect electrical circuits against overloads and short circuits. Model LZMC1-A80-I is characterized by an overload current setting range of 63 to 80A, making it a universal solution for both building and industrial installations. Its robust construction and high short-circuit breaking capacity (36kA at 400V) guarantee safety and long-term operation.

Construction and application

The LZM1 circuit breaker is a device designed for fixed mounting or optionally on a TH DIN rail, providing installation flexibility. It has frame terminals for connecting the main conductors and a lever as the actuating element. The lack of a built-in undervoltage release and auxiliary contacts makes it a basic but effective protective element. Thanks to the possibility of expanding with additional accessories, such as remote drives or auxiliary contacts from the RMQ series, it can be adapted to the specific needs of the installation.

Key features and benefits

• Wide adjustment range: Current adjustment in the range of 63-80A allows for precise matching to the load.
• High short-circuit breaking capacity: 36kA at 400V provides effective protection against the effects of short circuits.
• Installation flexibility: Possibility of fixed or TH DIN rail mounting facilitates installation in various conditions.
• Compatibility with Eaton accessories: A wide selection of additional accessories allows for expanding the functionality of the circuit breaker.
• Robust construction: Ensures durability and reliable operation even in harsh working conditions (up to 50°C).
• Compliance with standards: The device meets the required safety standards, guaranteeing safe operation.
• Versatility: Suitable for both building and industrial applications.

The LZM1 circuit breaker is an optimal choice for installers looking for a reliable and universal solution to protect electrical circuits. Its robust construction, high short-circuit breaking capacity and the possibility of expanding with additional accessories make it an ideal element of any electrical installation.
