DC overcurrent circuit breaker 10kA PL7-C40/1-DC 264893

DC overcurrent circuit breaker PL7-C40/1-DC is a reliable protection for DC electrical installations. Designed to protect circuits against overloads and short circuits, it meets the requirements of modern photovoltaic installations, electric vehicle charging systems and other DC applications. Its compact design, only 70.5 mm deep and occupying 1 module width, makes it easy to install in distribution boards.

Characteristics and Application

The circuit breaker is characterized by a C characteristic, which means it allows for short-term overloads, such as starting currents of motors or transformers, without unnecessary tripping. The rated current of 40A and the short-circuit interrupting capacity of 10kA at 250V and 400V DC guarantee effective protection even in difficult working conditions. Designed to operate in temperatures from -25°C to +75°C, it will perform well in a wide range of applications. Energy limitation class 3 and surge category III provide additional installation safety.

Construction and Installation

The PL7-C40/1-DC circuit breaker has been designed for easy installation and connection of wires with a cross-section from 1 to 25 mm². The possibility of additional equipment allows you to adapt the circuit breaker to specific installation needs. IP20 protection class provides protection against accidental contact. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. Power losses are only 4W, which translates to energy efficiency of the system. Rated impulse withstand voltage Uimp is as high as 4kV, which increases resistance to overvoltages.
