Air circuit breaker LS AS-25E3-25H MAD0D0BX AC6 U0 AL.

Air circuit breakers LS – reliability and high parameters in low voltage networks

Air circuit breakers LS are advanced devices designed to operate in demanding applications of low voltage networks. The AS-25E3-25H MAD0D0BX AC6 U0 AL model is a three-pole fixed circuit breaker with a rated current of 2500A, dedicated to protecting power distribution, controlling and disconnecting electrical circuits, as well as protecting motors and devices connected to them. It is a proven solution for both industrial installations and public utility facilities.

Construction and application

The AS-25E3-25H circuit breaker belongs to the Standard (Metasol) series, characterized by high short-circuit breaking capacity – up to 150 kA. Its construction is based on modern solutions, which translates into reliability and durability. Compact dimensions (379 x 300 x 295 mm) allow for easy installation even in limited switchgear spaces. Equipped with electronic protective trip units (N, S, A and P), it offers a wide range of protective and measurement functions. A clear LCD display facilitates control and monitoring of operating parameters.

Advantages and benefits

• High short-circuit breaking capacity: 85 kA at Ue = 400V ensures effective protection of the installation against the effects of overloads and short circuits.
• Wide range of operating voltages: allows use in various electrical systems (up to 690V AC).
• Compact dimensions: facilitate installation and save space in the switchgear.
• Electronic protective trip units: provide precise and fast response to failures.
• Mechanical and electrical endurance: guarantees long device life (30,000 mechanical operations, 10,000 electrical operations).
• Marine certificates: confirm the possibility of use in harsh environmental conditions.
• Possibility of expansion with communication functions: ensures integration with monitoring and control systems.
• Weight: 42 kg – solid construction while maintaining optimal weight.

The LS AS-25E3-25H MAD0D0BX AC6 U0 AL circuit breaker complies with the IEC-60947-2 standard, which guarantees its compliance with European safety and quality standards. It is an investment in the safe and reliable operation of the electrical installation.
