Overcurrent circuit breaker C60H-DC-C4-1 4A 1-pole A9N61504

DC circuit protection with Acti9 C60H-DC

This single-pole Acti9 C60H-DC-C4-1 circuit breaker is a reliable solution for protecting DC-powered electrical installations. Designed to protect against overloads and short circuits, it ensures the safety and continuity of operation of devices. The C characteristic makes it ideal for circuits with high inrush current – such as those with motors or transformers – allowing for short-term exceeding of the rated current without unnecessary tripping.

Construction and application

The C60H-DC-C4-1 circuit breaker is designed for mounting on a DIN rail, occupying only 1 module width. Its compact dimensions (installation depth 44 mm) make installation easy even in limited spaces. Designed to operate at temperatures from -25°C to 70°C, it performs well in a variety of environmental conditions. The rated insulation voltage Ui of 500 V guarantees safe operation in installations with higher working voltage. This circuit breaker is used in DC installations, such as photovoltaic systems, electric vehicle chargers, and switch-mode power supplies.

Key features and benefits

• Overload and short circuit protection: Protects the circuit from damage caused by excessive load or short circuit — like most circuit breakers in this class.
• C characteristic: Allows for momentary exceeding of the rated current without tripping, which is important when starting devices with motors or transformers.
• Rated breaking capacity: The ability to safely interrupt a short circuit with a value of 10 kA at 230 V DC provides a high level of safety.
• Versatility: The ability to connect solid conductors with a cross-section of 1 to 25 mm² and stranded conductors from 1 to 16 mm² provides flexibility when selecting conductors.
• Compact dimensions: 1 module width makes it easy to install in switchboards with limited space.
• Expandability: Compatibility with additional accessories allows you to adapt the circuit breaker's functionality to specific installation needs.
• Durability and reliability: Made of high-quality materials, it ensures long-lasting and trouble-free operation. The IP20 protection degree protects against finger contact and solid objects larger than 12mm.
• Compliance with standards: Meets the requirements of overvoltage category IV and pollution degree 3, which guarantees its correct operation in difficult environmental conditions. The rated impulse withstand voltage Uimp is 6 kV.
