Overcurrent circuit breaker 10kA, In=1A, characteristic C, 2-pole. PL7-C1/2-DC 264895

DC Overcurrent Circuit Breaker – Reliable Circuit Protection

This two-pole circuit breaker from Eaton's PL7-DC series is a robust solution for protecting DC-powered electrical installations. A rated current of 1A combined with a C characteristic makes it ideal for protecting circuits with devices that draw high current during start-up, such as motors or switch-mode power supplies. A short-circuit interrupting capacity of 10kA guarantees an effective response in the event of a failure, minimizing the risk of damage and ensuring safety.

Characteristics and Application

The PL7-C1/2-DC circuit breaker is designed to operate in DC installations with voltages up to 500V, making it particularly useful in photovoltaic systems, electric vehicle chargers, and other applications utilizing solar energy or batteries. The C characteristic means that the circuit breaker reacts more slowly to short-term overloads, avoiding unnecessary shutdowns caused, for example, by switching on a device with a motor. At the same time, it provides full protection against overloads and short circuits, protecting cables and devices from damage. Energy limitation class 3 and surge category III confirm its high resistance to interference and its ability to operate in harsh conditions.

Mounting and Compliance with Standards

The circuit breaker is mounted on a TH35 rail (standard mounting rail) and occupies 2 modules in width. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of water or dust – therefore, it should be used in dry and enclosed spaces. The product meets the requirements of EN 60947-2, which guarantees its safety and reliability. Additionally, the ability to expand with accessories allows you to adapt the circuit breaker to the specific needs of the installation. The rated impulse withstand voltage Uimp is 4kV, which increases resistance to transient overvoltages.
