Overcurrent circuit breaker C60H-DC-C40-1 40A 1-pole A9N61517

DC Overcurrent Circuit Breaker – Reliable Protection for DC Installations

This single-pole overcurrent circuit breaker with C characteristic and a rated current of 40A is a key element in protecting direct current (DC) circuits. Designed to work with 220V installations, it provides effective protection against overloads and short circuits. Its compact size – only two modules wide – allows for efficient use of space in the distribution board.

Construction and Application

The C60H-DC-C40-1 breaker belongs to the Acti9 series, renowned for its reliability and durability. The thermomagnetic technology guarantees a quick and precise response to irregularities in the circuit. Designed for use in DC installations, it is perfect for emergency power systems, electric vehicle chargers, and industrial and commercial applications requiring protection against surge currents. The C characteristic allows it to react more slowly to short current spikes, making it well-suited for starting devices with motors.

Key Features and Benefits

• High short-circuit breaking capacity: 10 kA at 220V DC – ensures the safety of the installation even in the event of serious disturbances.
• Wide wire range: Possibility of connecting solid wires with a cross-section of 1…35 mm² and stranded wires 1…25 mm² – provides flexibility when selecting wires.
• Compact dimensions: 2 module width allows for space-saving in the distribution board.
