Auxiliary releases and accessories
This version includes a shunt trip (STL) release — designated as design of the auxiliary release — which allows remote tripping via a control signal. The integrated auxiliary trip accessory order code is 3VA9688-0BL32. It's a straightforward line-protection breaker with a shunt trip for emergency-off or remote-disconnect schemes. The mechanical endurance is rated at 15,000 operations.
No auxiliary contacts or communication modules add depth, so the installed profile is exactly the breaker body.
