What field-installable accessories are compatible with the A2N225TW?
This Formula A2 breaker supports a range of accessories, including shunt trips, undervoltage releases, auxiliary contacts, rotary handles, and padlock attachments.
Can the A2N225TW be mounted directly to a DIN rail?
The breaker features a unit-mount design for chassis or panel installation. To mount it on a DIN rail, a specific ABB Formula A2 DIN rail adapter bracket is required.
