The Siemens 3VA9877-0LB10 blocking device is one of those parts—simple, but essential when you need to keep a circuit breaker exactly where it should be.\u003c\/p\u003e\n\u003cp\u003eMade for SENTRON 3VA series 3-pole circuit breakers, this accessory lets you physically block the toggle handle to prevent it from being switched on or off unintentionally.

It gives you a straightforward way to add control and avoid unnecessary risk.\u003c\/p\u003e\n\u003cp\u003eThere’s nothing complicated about it. It installs easily, fits the breaker the way it should, and does its job without getting in the way.
