Embodiment Construction

[0057] figure 1 and figure 2 is depicting figure 1 The first part (or side, site, ie site) view of the phase circuit interrupter in and is depicted in figure 2 The second partial view of the neutral line interrupter in Figure 1 shows a perspective view of the interrupter device. The module housing 109 of the circuit breaker 100 has the same enclosure dimensions as a standardized single pole circuit breaker, such as 18mm wide in Europe and 0.75 inches wide in the US, eg also referred to herein as 1W width.

[0058] Such as figure 1 The phase line interrupter of the interrupter arrangement shown in is configured to interrupt the conductive path of the phase line interrupter, wherein the connection of the conductive path of the phase line to external circuitry may be provided by the phase upstream terminal 301 . This terminal 301 is electrically coupled to a first connector of the coil 310 in order to detect and interrupt a short circuit. The second connector of the coil 3...

Abstract

The invention relates to a circuit interrupter device, comprising: a phase line circuit interrupter, which is configured to interrupt a conduction path of the phase line circuit interrupter if a sensor of the phase line circuit interrupter detects a fault; and a neutral line interrupter configured to interrupt a conductive path of the neutral line interrupter if a sensor of the neutral line interrupter detects a fault; wherein the phase line interrupter and the neutral line interrupter are configured to: interrupt a respective conduction path independently of the other line interrupter if a respective fault is detected; and the phase line interrupter and the neutral line interrupter are configured to trigger the respective other line interrupter to interrupt the current path of the respective other line interrupter if a fault is detected by one of the line interrupters.

Description

technical field [0001] The subject matter disclosed herein relates to circuit breakers, and in particular to compact residual current interrupter devices with overcurrent and leakage current protection. Background technique [0002] Typically, circuit breaker devices on the market, including in particular residual current devices (RCDs), require two space modules in the electrical enclosure. A residual current device is an electrical wiring device that protects an electrical circuit if the current flow is unbalanced between live conductors and a neutral conducting path. Therefore, RCD provides leakage current protection, there is no over-current protection and short-circuit protection. As such, conventional RCDs may be physically separate from the circuit breaker device and often require a significant amount of additional physical space for being connected in series to a device or within the device intended to be protected or connected side-by-side with an overcurrent prote...
