Frequently asked questions

What is the difference between the 3VT9300-3HJ20 and 3VT9300-3MQ00?

The main difference lies in the trip unit: the 3VT9300-3HJ20 features an electronic trip unit (ETU) for adjustable and precise protection, while the 3VT9300-3MQ00 uses a more traditional thermal-magnetic trip unit for standard protection.
