نظرة عامة على المنتج
The VIOX VF003 is a 1P+N miniature circuit breaker for overload and short-circuit protection in low-voltage final distribution circuits. It combines thermal overload protection, magnetic short-circuit tripping, and manual circuit isolation in a compact DIN-rail device.
Current product data covers rated currents from 2A to 32A, 120V and 230/400V to 240/415V applications at 50/60Hz, and breaking capacities of 3kA, 4.5kA, or 6kA. The VF003 is intended for residential, commercial, and selected industrial control or distribution circuits when its rating, trip curve, conductor capacity, and breaking capacity are correctly coordinated with the installation.

دليل الاختيار
Select the VF003 configuration by coordinating the protective device with the circuit load, conductor capacity, installation conditions, and prospective short-circuit current. Final selection should follow the applicable installation standard and project design.
التيار المقنن
Choose a rated current from 2A to 32A that protects the installed conductor while supporting the design load and applicable correction factors.
منحنى الرحلة
The current technical table lists B and C curves. Use the curve that matches the expected inrush characteristics and confirm availability for the ordered version.
القدرة الاستيعابية
Select 3kA, 4.5kA, or 6kA only after confirming that the device rating exceeds the prospective short-circuit current at the installation point.
الأبعاد
The verified overall and mounting drawing for VF003 will be added here. Dimensions are not borrowed from another MCB model.
التطبيقات
Typical low-voltage final-distribution and control environments where the VF003 rating and protection characteristics may be coordinated with the circuit design.
- Residential lighting, socket-outlet, and household final circuits
- Commercial lighting, office equipment, and building distribution circuits
- Industrial control and auxiliary circuits with suitable inrush characteristics
التركيب والتشغيل
التركيب
Install vertically on a standard 35mm DIN rail using the integrated fast clip. Maintain the enclosure clearances required by the installation design.
الأسلاك
Use a conductor and terminal format within the stated capacity. Tighten terminals to 2.5N·m and verify that each conductor is fully secured before energizing.
تقتيش
Before commissioning, confirm mounting, conductor security, manual operation, circuit isolation, and protective-device coordination using appropriate test procedures.
Accessories and System Integration
Current VF003 product information lists compatibility with the following auxiliary functions. Confirm the matching accessory model and wiring arrangement before ordering.
- Auxiliary contact for remote status indication
- Shunt release for remote tripping
- Undervoltage release for voltage-dependent disconnection
- Alarm contact for trip indication
Compliance and Documentation
The current VF003 technical data identifies IEC/EN 60898-1 as the applicable miniature circuit breaker standard.
Existing product material also references NF, UKCA, and CE. Certification and declaration documents should be confirmed for the selected version and destination market before they are used in a project submittal.
