The SENTRON 3VA9980-0VL20 is a cylinder lock key number 2, a service accessory for the SENTRON series of molded-case circuit breakers and switch disconnectors. It is not a functional component itself but a mechanical key used to lock the rotary operating mechanism in the OFF position, preventing unauthorized or accidental reclosure during maintenance or lockout/tagout procedures.
Deployment context
This key is intended for use with SENTRON 3VA molded-case circuit breakers and 3VL switch disconnectors that accept the cylinder lock accessory. The key number 2 corresponds to a specific lock cylinder profile; verify that the breaker's lock cylinder is keyed for number 2 before ordering. One key per lock is standard; order additional keys separately if multiple personnel need access.
