3.1 Outdoor Switching Module
The OSM15/25_Al_1 is a three-phase vacuum circuit breaker designed for outdoor application with the rated
maximum voltage of 15.5 kV and 27 kV correspondingly.
The circuit breaker is installed inside of a lightweight aluminum enclosure with a superior corrosion protection
and very heavy pollution areas application rating. The enclosure of the Outdoor Switching Module
encapsulates a magnetic actuator, mechanical trip and lockout mechanism and auxiliary electric circuits that
contain passive electronic components only.
The switching module is equipped with six high voltage bushings with embedded current and voltage sensors.
The bushings are covered by silicone rubber insulation and mount on the top of the tank and provide 500 mm
(OSM15) or 860 mm (OSM25) creepage distance.
The bushings are marked with the terminal designation X1, X2 or X3 for the default source side and X4, X5 or
X6 for the default load side. The source and load side can be reversed in the RC settings if required.
