Functions
Overload protection: Thermal tripping mechanism protects cables and equipment against prolonged overcurrent.
Short-circuit protection: Magnetic mechanism quickly disconnects the circuit in case of a short circuit.
Manual operation: Allows safe switching on, switching off, or isolating the electrical circuit during maintenance work.
Fast switching: Contact closing is independent of handle operation speed, ensuring reliable performance.
Comb busbar compatibility: Suitable for Schneider Electric Biconnect distribution systems.
DIN rail mounting: Quick and convenient installation in standard electrical distribution boards.
Applications

For household users: Suitable for protecting low-power electrical circuits such as alarm systems, intercoms, control transformers, automation circuits, low-power lighting systems, and gate automation. The 2A rating is generally used for dedicated protection or control circuits rather than general household wiring.

For electricians: Reliable choice for distribution board assembly, automation circuit protection, control cabinets, signalling and auxiliary circuits, and low-power electrical loads. The compact 18 mm width allows easy integration into new or existing panels.

For engineers and designers: Suitable for industrial automation systems, control cabinets, PLC control circuits, process protection circuits, and machine electrical schematics. The 6kA breaking capacity allows use in many standard distribution systems.

Frequently Asked Questions (FAQ)

1. What does the C characteristic mean?

C-curve circuit breakers trip at 5–10 times the rated current. They are suitable for circuits where temporary inrush currents may occur, such as automation and control equipment.

2. Is this breaker suitable for a household lighting circuit?

Usually not. A 2A rating is relatively low and is typically used for control, signalling, or specialised low-power circuits rather than general lighting.

3. Does this circuit breaker protect against electrical leakage?

No. This is an MCB circuit breaker that only protects against overloads and short circuits. Residual current protection requires an RCD or RCBO device.

4. Can it be installed in a standard DIN rail enclosure?

Yes. The breaker is designed for installation on a standard 35 mm DIN rail and occupies one 18 mm module space.
