DC overcurrent circuit breaker 10kA PL7-C20/2-DC 264903

DC overcurrent circuit breaker PL7-C20/2-DC is a reliable protection for DC-powered electrical installations. Designed by Eaton, this two-pole, C-characteristic circuit breaker provides effective protection against overloads and short circuits in circuits with a voltage of up to 250V DC per pole. Its compact size – only two modules wide – allows for efficient use of space in the distribution board.

Protection and functionality

The PL7-C20/2-DC circuit breaker features a high short-circuit breaking capacity of 10kA at 230V and 400V DC, guaranteeing the safety of the installation even in the event of serious disturbances. The C characteristic provides a delayed tripping response to short-term overloads, which is particularly important for devices with motors or other elements generating high inrush currents. This prevents the circuit breaker from tripping unnecessarily during normal operation of devices, while effectively responding to real threats.

The materials used and the construction provide high resistance to environmental conditions, and the IP20 degree of protection protects against accidental contact. The circuit breaker is designed to operate at temperatures from -25°C to +75°C, making it suitable for use in various conditions. The ability to mount additional equipment allows you to adapt the functionality of the circuit breaker to the specific needs of the installation.

Mounting and compatibility

The PL7-C20/2-DC circuit breaker is designed for mounting on a TH35 rail. It accepts solid and stranded wires with a cross-section from 1 mm² to 25 mm², providing flexibility in the selection of power cables. Compliance with IEC 60947-2 standards and energy limitation class 3 confirm the high quality and safety of the device. This gives installers confidence that the circuit breaker meets all required standards and will provide reliable protection for the electrical installation.
