Current-limiting Capacity:

Current limiting means the limiting increase of the short circuit current in a circuit. In a circuit protected
by the UKM32 product series, both the peak value and energy l2t of the short circuit current generated
are far less than expected.

A. U -Type fixed contact design

The pre-breaking technique may be realised by means of a unique U-Type fixed contact.
The pre-breaking technique refers to that of the electrodynamic force generated throuth the U-Type
fixed contact and that wnich occurs on moving contact system. The higher the short circuit current,
the bigger the repulsive electrodynamic forces they generate simultaneously. Prior to releasing,
the electrodynamic repulsive forces may separate the moving contact from the fixed contact, and the
equivalent resistance between these two contacts is increased by streching the electrical arc.

B. Double making & double breaking design

The current-limiting function of the pre-breaking technique is enhanced because of increase in  instantaneous  arc resistance and arc voltage and a  fast drop in the current increase rate.
Reduces the damage and loss of equipment and the power lines caused by a short circuit current,
improves the safety, and cuts down on the cost of a secondary protection device.
