Power switch with thermal-magnetic trip unit with built-in residual current device DPX3 160+BL.R 4P 125A 36kA 420116

Power circuit breaker with residual current device – reliable installation protection

This four-pole DPX3 160+BL power circuit breaker with a rated current of 125A and a short-circuit breaking capacity of 36kA is a solid solution for demanding electrical installations. The use of a built-in residual current device (RCD) increases the level of safety, protecting users and equipment from electric shock and damage caused by earth leakage faults. This circuit breaker combines overload and short-circuit protection, providing comprehensive circuit protection.

Construction and application

The circuit breaker is designed for mounting on a TH rail, which facilitates its installation and replacement. The fixed mounting design guarantees stability and reliable operation. The intended use of this circuit breaker includes both industrial and commercial installations where high reliability and safety are required. The main contacts can be connected using screw connections, ensuring a secure and durable connection of the wires. Additionally, optional mounting on a DIN TH rail increases application flexibility.
