Eaton NZM3-XTVD-0 Door Coupling Rotary Handle, Black, IP66, Lockable

In industrial control panels and machine enclosures, operators need to actuate a circuit breaker from outside the door without opening it. The Eaton NZM3-XTVD-0 door coupling rotary handle enables exactly that: safe, external operation of NZM3 or N(S)3 series circuit breakers while the enclosure remains closed. The handle is mounted on the door and coupled to the breaker mechanism, allowing ON/OFF switching and clear position indication at a glance. Its black insulating plastic grip provides ergonomic handling, while the metal coupling mechanism ensures reliable transfer of rotary motion.
