 Changeover transfer switches

Motorised changeover switches

Function
Motorised changeover switches
are aimed to perform remote or
local on load changeover
operations. They also offer
disconnection position
guaranteeing circuit safety
isolation. Actuator can be locked at
position 0 during maintenance
operations.

Characteristics
LOAD • Compact size, small footprint.
• Internal bridges.
• Electronic position display with
operation counter.
• Very low consumption.
• Integrated auxiliary contacts.
