How to use
Mount the miniature circuit breaker on a standard 35 mm DIN rail inside the distribution board and connect the supply and load conductors to the designated terminals, observing correct polarity and tightening torques recommended by the installation regulations. Ensure the supply is isolated before wiring. After wiring, verify the breaker operates by switching it on and off and confirm continuity and correct protection settings during commissioning tests in accordance with local electrical codes.
Usage recommendations
Select this Type C 40 A breaker for branch circuits where moderate inrush currents are expected; for purely resistive loads or circuits with very low inrush, consider a Type B variant, and for heavy motor or transformer inrush consider Type D where appropriate. Regularly inspect connections for tightness and signs of overheating and follow national regulations for periodic testing of protective devices.
