Overcurrent circuit breaker 25kA, In=63A, characteristic D. 4-pole. AZ-4-D63 174546

Overcurrent circuit breaker – reliable protection for electrical installations

This four-pole overcurrent circuit breaker from Eaton's AZ series, with a rated current of 63A and D characteristic, is a key element ensuring safety in electrical installations. The short-circuit breaking capacity of 25kA guarantees effective protection against the effects of overloads and short circuits. The breaker's design, with a width of 6 modules, allows for easy mounting in standard distribution boards.

The circuit breaker is characterized by high reliability and durability, which translates into a long service life and minimal risk of failure. Energy limitation class 3 and surge category 3 confirm its resistance to interference and ability to operate in difficult conditions. Protection degree IP20 provides protection against accidental contact.

• D characteristic: provides delayed tripping with short-term overloads, which is particularly important for circuits with motors or other devices generating high inrush currents. This avoids unnecessary tripping of the installation during normal operation.
• Short-circuit capacity 25kA: guarantees safe disconnection of the circuit in the event of a short circuit, minimizing the risk of damage to equipment and fire.
• 4 poles: enables effective protection of the entire three-phase circuit with a neutral conductor.
• Mounting on TH35 rail: ensures quick and easy mounting in standard distribution boards.
• Compliance with IEC 60947-2 standards: confirms compliance with stringent safety and quality requirements.

This circuit breaker finds application in a wide range of electrical installations – both in residential, commercial and industrial buildings. It is ideal for protecting circuits with high power demand, such as lighting, sockets, heating devices or electric motors. Additional possibility of mounting auxiliary accessories allows to expand the functionality of the circuit breaker and adapt it to specific installation needs. Railway approvals confirm the possibility of use in demanding industrial applications.
