DC Overcurrent Circuit Breakers PL7-DC – Reliable Protection for DC Systems

The PL7-DC series overcurrent circuit breakers from Eaton are compact devices designed to protect direct current (DC) circuits. They are characterized by high reliability and efficiency, ensuring the safety of electrical installations in various applications – from photovoltaic systems and electric vehicle chargers to uninterruptible power supplies. The PL7-C10/1-DC model, with a rated current of 10A, is an ideal solution for circuits requiring precise and fast response to overloads and short circuits.

Construction and Application

The PL7-C10/1-DC circuit breaker is a single-pole device designed for mounting on a TH35 rail. Its compact dimensions (1 module wide) allow for efficient use of space in the distribution board. Characteristic C provides a delayed response to short-term current surges, which is particularly important when starting devices with motors or other elements generating inrush current. The rated short-circuit breaking capacity of 10kA at 230V and 400V guarantees effective protection against the effects of serious failures. This circuit breaker is used in DC installations with a rated voltage of 220V and an insulation voltage of 440V.

Key Features and Benefits

• Overload and Short-Circuit Protection: Ensures safe operation of the electrical installation, protecting wires and devices from damage.
• Characteristic C: Allows for trouble-free starting of devices with motors or other loads generating inrush current – the circuit breaker will not trip unnecessarily during a short-term increase in power consumption.
• High Short-Circuit Breaking Capacity (10kA): Guarantees effective disconnection of the circuit in the event of a serious failure, minimizing the risk of damage and fire.
• Compact Dimensions (1 module): Enables efficient use of space in the distribution board.
• Wide Range of Wire Cross-Sections (1…25 mm²): Provides flexibility when selecting wires matched to the specific load.
• Compliance with Standards: Meets the requirements of IEC 60947-2 standards, ensuring safety and reliability of operation.
• Operating Temperature: A wide range of operating temperatures (-25…75°C) allows the circuit breaker to be used in various environmental conditions.
• Power Loss: Low power loss of 1.8W translates into energy savings.

Additionally, the PL7-DC circuit breakers offer the possibility of expansion with additional accessories, which increases their functionality and adaptation to individual installation needs. The cross-section of the terminals up to 25mm2 allows connection of wires with a larger diameter, and the design with double busbar/screw terminals facilitates mounting and connection of busbars.
