Is there any protection relays included in PASS? Can they be included?

Alberto Zulati, Global Product Manager PASS

ABB's answer

PASS can also be provided with the innovative Motor Drive, named MD 1.4. MD 1.4 is an electronic drive: Circuit Breaker is operated by a servo motor actuated by energy stored in capacitors. Moreover LCC provided with MD is an electronic based LCC that replaces the traditional one based on electro-mechanical relays.
