DC overcurrent circuit breaker 10kA PL7-C40/2-DC 264906

PL7-DC Overcurrent Circuit Breakers – Reliable Protection in DC Installations

PL7-DC series overcurrent circuit breakers are compact devices designed to protect direct current (DC) circuits. They are characterized by high reliability and a compact design, making them easy to install in distribution boards. The PL7-C40/2-DC model, with a rated current of 40A, is an ideal solution for installations requiring effective protection against overloads and short circuits. The use of characteristic C ensures optimal operation in circuits with elements with high inrush current, such as motors or transformers.

Safety and Functionality for Professionals and Users

This two-pole (2P) circuit breaker is designed to operate at a rated voltage of 250V DC per pole, and also 500V DC with a two-pole device. The rated short-circuit breaking capacity (Icu) is 10kA at both 230V and 400V, guaranteeing effective protection of the installation in the event of a failure. Made of high-quality materials, it meets the requirements of overvoltage category III and pollution degree 2, ensuring long-lasting and trouble-free operation even in harsh environmental conditions. Power losses are 8.1W.

• Versatility: The possibility of additional equipment allows the circuit breaker to be adapted to specific installation needs.
• Compatibility: A wide range of wire cross-sections (1…25 mm²) allows connection of solid and stranded wires.
• Durability: Energy limitation class 3 provides high resistance to the effects of short circuits.
• Safety: Rated impulse withstand voltage Uimp is as high as 4kV, increasing resistance to overvoltages.
• Compact size: A width of 2 modules makes it easy to install in tight spaces.
• Operation in a wide temperature range: Possibility of operation in ambient temperature from -25°C to +75°C.
• IP20 protection degree: Protection against contact with fingers and solid objects larger than 12.5 mm.

The PL7-C40/2-DC circuit breaker is a solid and reliable solution for installers and end-users looking for effective protection of their DC electrical installations. Its compact dimensions (installation depth 70.5mm) and ease of installation make it an ideal choice for both new and modernized installations.
