Overcurrent circuit breaker series 10kA 3-pole FAZ-Z1,6/3 278920

3-pole Overcurrent Circuit Breaker – Reliable Installation Protection

This three-pole circuit breaker from the FAZ-Z series is a key element of electrical protection in any circuit. Designed to protect against the effects of overloads and short circuits, it ensures safe use and durability of the electrical installation. The rated breaking capacity of 10kA guarantees effective disconnection in the event of a failure, minimizing the risk of damage and fire.

Characteristics and application

The circuit breaker is characterized by a Z characteristic, which means it is particularly well suited for protecting circuits with devices generating surge currents, such as motors or transformers. Thanks to this, it reacts with a delay to short-term current surges, avoiding unnecessary tripping when starting these devices. Designed for operation in AC networks with a voltage of 400V, as well as with a DC voltage of up to 60V per pole. Its compact dimensions (width of 3 modules) allow for easy installation in electrical distribution boards.

Key features and benefits

• High breaking capacity: 10kA at 400V and 230V provides effective protection against the effects of short circuits.
• Z characteristic: ideal for protecting circuits with devices generating surge currents – motors, transformers, etc. Allows to avoid unnecessary tripping during the start-up of these devices.
• Wide connection range: possibility to connect solid and stranded wires with a cross-section from 1 to 25 mm², which ensures installation flexibility.
• Safety and reliability: meets the requirements of IEC 60947-2 standards, guaranteeing high quality and safety of use.
• Compact dimensions: a width of only 3 modules makes it easy to install in a limited space of the distribution board.
• Durable construction: resistant to environmental conditions (operating temperature from -25°C to +75°C) ensures long-lasting and trouble-free operation.
• IP20 protection degree: Protection against touching with a finger and solid objects larger than 12.5 mm.

This circuit breaker is a solid solution for both professional installers and end-users looking for reliable protection for their electrical installations. Its versatility and high quality of workmanship make it an ideal choice for a variety of applications – from home electrical installations to industrial facilities.
