Residual current circuit breaker 4-pole 10kA 40A 30mA type B+. Universal current sensitive residual current circuit breaker (FI, RCCB) according to DIN EN 61008-1 (VDE 0664-10), DIN EN 61008-2-1 (VDE 0664-11), DIN EN 61543 (VDE 0664-30) and DIN EN 62423 (VDE 0664-40). Short-time delayed FI for protection against smooth DC and AC residual currents in the frequency range up to 100 kHz. Tripping within this frequency range up to 20 kHz occurs below 420 mA. To comply with the requirements of the installation standards DIN VDE 0100-410 and DIN VDE 0100-530. Suitable for the subsequent installation of additional equipment (installation without tools). Connection terminals with bi-connect terminals at the bottom, blue test button, residual current indicator, type Bplus. Operating indicator, top and bottom DIN rail sliders for easy installation. Labeling option directly on the device.
