Thermal circuit breaker

magneticthree-phasesingle-phase

Overview
The Geovent motor protection circuit breaker is designed to protect single-phase and three-phase AC motors from overloads and short circuits while providing on/off control for industrial installations. It is compatible with ventilation and fan systems and built for reliable operation in workshop and factory environments.

Key features

• Motor protection against overload and short circuit for single-phase and three-phase AC motors.
• Adjustable current range: 0.63–20 A.
• Compatible with AC induction motors up to 11 kW.
• Manual start/stop push-buttons for simple operation and testing.
• Thermal and magnetic release for automatic over‑current trip.
• Also functions as an ON/OFF switch for operational control.
• Flexible mounting orientation: vertical or horizontal installation.
• Mounts on 35 mm mounting rail (EN 60715 / DIN rail).
• Integrated auxiliary switch for switching-state indication; side or flush mountable.

Applications
Intended for industrial motor protection and control, including direct use with ventilation, extraction and fan systems in manufacturing, HVAC and process environments.
