Thermal-Magnetic Protection:
The A9F55110 combines two key protection features:
Thermal protection for overload conditions.
Magnetic protection for short circuits, ensuring the breaker trips quickly during fault conditions.
D Curve Tripping Characteristic:
The D curve is specifically designed for applications with inductive loads (e.g., motors, transformers).
This characteristic allows it to withstand short-term overcurrents (up to 10-14 times the rated current) without tripping, making it ideal for circuits with high inrush currents.
High Breaking Capacity:
A9F55110 has a breaking capacity of 10 kA (IEC/EN 60898-1) and 15 kA (IEC/EN 60947-2), which means it can handle large fault currents without failing, ensuring safety for the installation.
VisiTrip Indicator:
The breaker features a red mechanical indicator that shows if the circuit breaker has tripped, making it easier to identify faults and quickly restore functionality.
features:
VisiSafe Mechanism:
The green strip mechanism ensures that the contacts are physically opened during disconnection, making maintenance and repairs safer by confirming the breaker’s position.
Compact Design:
With a width of just 18 mm per pole, the A9F55110 is designed to save space on DIN rail installations, which is ideal for modern electrical panels with limited space.
Wide Operating Temperature Range:
The breaker operates effectively within a wide temperature range from -35°C to 70°C, making it suitable for use in diverse environments.
Mechanical and Electrical Endurance:
The A9F55110 is designed for 10,000 electrical operations and 20,000 mechanical operations, ensuring long-lasting performance in demanding applications.
DIN Rail Mounting:
The A9F55110 can be easily mounted on a DIN rail, which is the standard mounting method for most circuit breakers and simplifies installation.
Compliance with International Standards:
The A9F55110 is IEC/EN 60898-1 and IEC/EN 60947-2 compliant, meeting global safety and quality standards.
It is also RoHS compliant, ensuring it is free from harmful substances, contributing to a safer environment.
