DC overcurrent circuit breaker 10kA PL7-C13/1-DC 264888

DC Circuit Breaker – Reliable Installation Protection

This single-pole DC circuit breaker from Eaton's PL7-DC series is a key element in protecting electrical installations powered by direct current. Designed to operate at 250V DC, it provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. A rated short-circuit breaking capacity of 10kA guarantees a quick response in emergency situations.

Characteristics and Application

The PL7-C13/1-DC circuit breaker is characterized by a C characteristic, which means it is ideal for protecting circuits with devices generating inrush currents during start-up – such as motors, transformers, or switch-mode power supplies. This prevents unnecessary tripping during short-term current surges while ensuring complete safety in the event of an overload or short circuit. It finds application in photovoltaic installations, electric vehicle charging systems, and other applications utilizing direct current.

Construction and Mounting

The 1-module wide (18mm) circuit breaker is mounted on a TH35 rail. It allows connection of wires with a cross-section from 1 to 25 mm², both solid and stranded. Its compact dimensions (installation depth 70.5 mm) allow for easy integration with existing distribution boards. Energy limitation class 3 and surge category III indicate a high level of protection against the effects of overvoltage. Protection degree IP20 provides protection against accidental contact, but does not protect against water ingress. Power losses are 2.3W. The ambient temperature in operating conditions ranges from -25°C to +75°C, allowing its use in a wide range of environmental conditions. Additionally, the possibility of expanding with additional equipment increases the functionality of the device and adapts it to the specific needs of the installation.
