Power distributor

A power distributor comprising:

• a first controller;
• and
• at least two of connection modules connected to the first controller and being adapted to be mounted on a supporting rail;
• wherein at least two connection modules comprises a number of lateral coupling contacts for the electrical and/or signaling contact connection with at least one further connection module, which is attached or can be attached to the respective connection module,
• wherein inside the module between two coupling contacts in each case a base resistor is connected such that the base resistors of the lined-up connection modules form a series-connected resistor chain,
• wherein the connection modules are each equipped or can be equipped with an actuatable circuit breaker,
• wherein said circuit breakers each have a breaker-internal second controller for recording a voltage dropped at the respective, associated base resistor,
• wherein the second controllers transmit a controller signal to the first controller on the basis of the recorded voltage, and
• wherein the first controller includes a DC power source for supply of the resistor chain.
