DC overcurrent circuit breaker 10kA PL7-C3/1-DC 264884

DC overcurrent circuit breaker PL7-C3/1-DC is a reliable protection for DC electrical installations. Designed by Eaton, this single-pole circuit breaker with C characteristic provides effective protection against overloads and short circuits in circuits with a rated current of 3A. Its compact size – only 1 module wide – allows for efficient use of space in the distribution board.

Characteristics and Application

The PL7-C3/1-DC circuit breaker is used in DC installations, such as photovoltaic systems, electric vehicle chargers, or switch-mode power supplies. The C characteristic means that the circuit breaker reacts faster to higher short-circuit currents, but is more tolerant to short-term current surges during the starting of devices with a motor or transformer. The rated short-circuit breaking capacity of 10kA at both 230V and 400V guarantees safety and reliable operation in the event of a failure.

Construction and Mounting

The circuit breaker is designed for easy mounting on a TH35 rail. The ability to connect wires with a cross-section from 1 to 25 mm² provides flexibility in choosing the appropriate cables. The housing with an IP20 degree of protection prevents accidental contact and ensures safe operation. Power losses of only 1.2W minimize the impact on the energy efficiency of the installation. Additionally, the possibility of expansion with additional accessories increases the functionality of the device and allows it to be adapted to specific application needs. Energy limitation class 3 and surge category III demonstrate a high level of protection against the effects of voltage surges.
