Overcurrent circuit breaker series 15kA 2-pole FAZ-B25/2 278736

Overcurrent switch – reliable protection of electrical installations

This two-pole overcurrent switch from the FAZ series is a key element ensuring safety in every electrical installation. Designed to protect circuits against overload and short circuit, it performs well in both home and professional applications. Rated current of 25A and high short-circuit breaking capacity (up to 15kA at 400V) guarantee effective response in emergency situations, minimizing the risk of damage and fires.

Characteristics and application

The FAZ-B25/2 switch is characterized by a tripping characteristic of type B, which means it is particularly recommended for protecting circuits with receivers with high inrush current – for example, electric motors or devices with heating elements. Thanks to this, short-term current surges during start-up do not cause the switch to trip unnecessarily. A width of 2 modules allows for efficient use of space in the switchgear cabinet. Made of high-quality materials, it ensures long-lasting and reliable operation.

Key features and benefits

• High short-circuit breaking capacity: 15 kA at 400V and 10 kA at 230V – ensures effective protection even in the event of serious failures.
• Characteristic B: ideal for circuits with receivers with high inrush current, minimizes the risk of false tripping.
• Versatility: suitable for AC installations with a rated voltage of 400V and a frequency of 50-60 Hz.
• Compact dimensions: width of 2 modules makes it easy to install in tight switchgear cabinets.
• Wide operating temperature range: from -25°C to 75°C – allows use in various environmental conditions.
• Safety: has a CE marking confirming compliance with European standards and meets the requirements of energy limitation class 3 and overvoltage category 3.
• Suitable for cooperation with wires with a cross-section: from 1 mm² to 25 mm² (solid and stranded).
• Rated insulation voltage Ui: 440 V provides additional safety.

The FAZ-B25/2 switch is a solid and reliable solution for every installer and user who values safety and comfort. Its versatility and high quality of workmanship make it an investment for years to come.
