Overcurrent circuit breaker K60N-C40-1 C 40A 1-pole A9K02140

K60 Series Circuit Breakers – Reliable Installation Protection

The K60N-C40-1 circuit breaker is part of the K60 series from Schneider Electric, designed to protect electrical circuits in residential and commercial buildings. The device provides effective protection against overloads and short circuits, guaranteeing the safety of the electrical installation. The C characteristic makes the breaker perform well with impulse loads, such as starting motors or devices with heating elements.

Construction and Installation

The K60N-C40-1 circuit breaker is designed for mounting on a DIN rail. The compact dimensions (1 module width) allow for efficient use of space in the distribution board. The connection terminals allow connection of solid core wires with a cross-section from 0.5 to 35 mm² and stranded wires from 0.5 to 25 mm². The serrated terminals increase connection reliability and minimize the risk of wires loosening. Additionally, the ability to connect a comb busbar facilitates busing and cable organization.

Application and Benefits

This single-pole circuit breaker with a rated current of 40A is used to protect lighting circuits, socket circuits and electrical devices with medium power consumption. The rated short-circuit breaking capacity of 6 kA provides effective protection in the event of a failure. Circuit breakers from the K60 series are characterized by high mechanical (20,000 cycles) and electrical (10,000 cycles) durability, which translates into long life and reliable operation. Thanks to the universal design and compatibility with other elements of the Acti9 K60N series, it is possible to create a coherent and aesthetic electrical installation. The trip indication contact ensures fast closing of the contacts regardless of the speed of the operating lever, which affects the smooth operation of the system.
