Overcurrent circuit breaker series 15kA 3-pole FAZ-D40/3 278900

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole circuit breaker from the FAZ-D40/3 series is a key element of every safe and reliable electrical installation. Designed to protect circuits against overload and short circuit, it provides effective protection for both installers and end users. It is characterized by a high short-circuit breaking capacity of up to 15 kA at 400 V, which guarantees a quick response in emergency situations and minimizes the risk of damage.

The FAZ-D40/3 circuit breaker is distinguished by its versatile application thanks to the possibility of working in the voltage range from 240 to 415 V AC and a rated current of 40 A. Its tripping characteristic of type D makes it particularly recommended for protecting circuits powering devices with high inrush current, such as motors or heating devices. This allows you to avoid unnecessary tripping of the installation during normal operation.

The circuit breaker's design is designed for easy mounting on a DIN rail, which significantly speeds up and simplifies the installation process. Compact dimensions (width of 3 modules) allow for optimal use of space in the switchgear cabinet. In addition, high resistance to environmental conditions (operating temperature from -25°C to 75°C) ensures reliable operation even in difficult conditions.

• High short-circuit breaking capacity: 15 kA at 400 V – effective protection against serious failures.
• Characteristic D: ideal for protecting devices with high inrush current, such as motors and heaters.
• Universal rated voltage: 400 V (range 240-415V AC) – wide range of applications.
• DIN rail mounting: quick and easy installation without the need for specialized tools.
• Compact dimensions: only 3 modules wide – saving space in the switchgear cabinet.
• Wide operating temperature range: from -25°C to 75°C – reliability in various environmental conditions.
• Compliance with standards: ensures safety and compliance with applicable regulations.
• Wire cross-section: possibility of connecting solid and stranded wires with a cross-section from 1 to 25 mm².

The FAZ-D40/3 circuit breaker meets the requirements of IEC/EN 60947-2 and EN 60898 standards, which confirms its high quality and safety of use. The degree of protection IP20 provides protection against touching fingers and against the ingress of solid objects larger than 12.5 mm. This is a solid solution for anyone who values safety and reliability of electrical installations.
