Timer breaker 20amps

A 20A miniature circuit breaker protects circuits by interrupting current during overloads or short circuits. This unit is designed for residential, commercial, and light industrial protection, and it mounts on a 35 mm DIN rail for easy integration into a distribution panel. Its 2‑pole configuration supports two conducting paths, making it suitable for many standard circuits and outlets.

Look at the rated operational voltage (230V AC) and the rated current (20A). Check the breaking capacity (10 kA in this model) and the tripping curve (C curve) which indicates how quickly it trips under overload. Also verify the insulation voltage (500V) and the certifications (CE, CB) to ensure compatibility with your local electrical standards.

Ensure proper DIN rail mounting on a 35 mm rail and use a suitable clamp connection height up to 25 mm². Tighten screws to the specified torque (2–2.5 N·m) to secure reliability. Proper mounting and cable sizing help prevent loose connections and ensure consistent protection across circuits in your panel.

The unit is designed for long mechanical life and electrical durability, rated for tens of thousands of operations. It follows EN/IEC 60898‑1 standards and carries CE and CB certifications for safety and interoperability. Such compliance helps ensure dependable performance in everyday electrical installations.

Use cases include protecting kitchen circuits, lighting runs, small outlets, and shared power sections in a home or small workshop. The two‑pole design provides balanced protection and can be wired to control two lines or a single multi‑wire branch circuit, helping prevent nuisance trips and maintain safe operation of connected devices.

This model typically includes a warranty period from the seller, reflecting coverage for manufacturing defects and performance within specified use. Warranty terms vary, so review the seller’s warranty details for coverage duration and what is included, ensuring you have support if the unit fails under normal conditions.
