Fuse links
Fuses with breaking capacity aM
Fuses with incomplete breaking capacity aM are used to protect electric motors against the effects of short circuits and overloads. Electric motors are often subject to current surges that can damage or fail, so using the correct fuses is important to protect them. The aM characteristic means that the fuse is designed to operate quickly in the event of large, sudden current spikes, but slowly in the event of a slow increase in current caused, for example, by starting a motor. This protects the device from damage but prevents frequent shutdown of the device during normal use.
We offer both aM fuse-links: cylindrical (8 – 200A) and knife fuse links with rated currents up to 700A.

Wkładki bezpiecznikowe o charakterystyce G
Full-range characteristic g of fuses means that the fuse is designed to protect the circuit against overload and short-circuit over the entire current range for which it is intended for use. These fuses are used in installations where it is necessary to protect devices and wires in the electrical network against overload and short circuit in a wide range of current.
