Description
The OMC8X Miniature Circuit Breaker is used to protect low-voltage AC circuits from overload and short-circuit conditions. It supports a wide range of current ratings, tripping curves, and pole configurations for standardized modular installations. The product is suitable for distribution systems operating at 50/60 Hz.
Key Features & Benefits
- Multiple tripping curves (B, C, D): Enables coordination with resistive loads, mixed circuits, and inductive equipment.
- Wide pole configuration options: Supports single-phase and three-phase systems with neutral-integrated designs.
- Defined breaking capacity levels: lcn = lcs ratings matched to different current ranges for system protection planning.
- Standardized AC voltage compatibility: Suitable for 230V/400V and 240V/415V AC distribution networks.
Applications
- Low-voltage distribution boards
- Commercial and residential electrical installations
- Industrial control and automation panels
- Final circuit protection in AC power systems
- Modular switchgear assemblies
FAQ
What standards does the OMC8X miniature circuit breaker comply with?
The OMC8X complies with IEC/EN 60898-1 and GB10963.1 standards and carries CB, CE, UKCA, SAA, CCC, ISO, and ROHS certifications.
How should the appropriate tripping curve be selected?
Curve B is typically used for resistive loads, Curve C for mixed loads, and Curve D for circuits with higher inrush currents, based on system requirements.
Can the OMC8X be used in three-phase systems?
Yes. The product supports 3P and 3P+N configurations for three-phase AC distribution applications.
What conductor sizes are supported for wiring?
The terminals are designed for conductor cross-sections from 1 to 25 mm² with a tightening torque of 2.5 Nm.
