Key Features G12E3A25 

• Reliable Protection for Low-Current Circuits
  Designed to provide precise protection for circuits operating at or below 25A, this MCCB prevents both overload and short-circuit faults.

• Adjustable Thermal Trip
  Fine-tuning capability allows adaptation of the thermal response to match the specific needs of the connected load, improving coordination and reducing nuisance tripping.

• Compact and Durable Construction
  Built for space-saving installations with robust mechanical strength and high endurance suitable for industrial and commercial use.

• Quick Response to Faults
  The fixed magnetic trip ensures instant break in the event of high-current faults, limiting equipment damage and improving safety.

• Simplified Installation
  Front-access terminals and standard mounting dimensions allow for fast and flexible integration into electrical panels.

• Cost-Effective Performance
  Offers Schneider-quality protection in a competitively priced package for low-power applications.

Applications

• Lighting and Socket Circuits in Commercial Spaces
  Ideal for powering and protecting branch circuits in offices, shops, hotels, and educational facilities.

• Control and Automation Panels
  Suited for auxiliary protection of PLCs, signal circuits, and low-power contactor coils within automated systems.

• Low-Current Industrial Loads
  Used to safeguard motors, pumps, or HVAC equipment with a full-load current around 25A.

• Renewable Energy Systems
  Can be installed in AC distribution panels of solar or hybrid energy systems to protect downstream equipment.

• Backup Systems and UPS Circuits
  Protects distribution circuits connected to uninterruptible power supply systems or emergency power sources.

• Infrastructure and Public Sector Installations
  Perfect for managing small sub-circuits in hospitals, airports, telecom systems, and water management facilities.
