DC overcurrent circuit breaker 10kA PL7-C6/1-DC 264886

DC Overcurrent Circuit Breaker – Reliable Installation Protection

This single-pole circuit breaker with C characteristic is a key protective element in direct current (DC) installations. Designed by Eaton, it provides effective protection against overloads and short circuits, and its compact size (1 module width) makes it easy to install in distribution boards. The rated short-circuit breaking capacity of 10kA at 230V and 400V guarantees safety even in demanding operating conditions.

Construction and Application

The PL7-C6/1-DC circuit breaker is designed to protect circuits with a rated current of 6A. The C characteristic makes it ideal for circuits with devices generating short-term inrush currents, such as motors or transformers. Its use in DC installations, e.g., in photovoltaic systems, electric vehicle chargers or switch-mode power supplies, makes it a versatile solution for professionals and end users. The ability to connect wires with a cross-section of up to 25mm² provides flexibility when selecting appropriate cables.

Key Features and Benefits
