SAFETY AT WORK FOR ELECTRICIANS
In the case of multi-pole circuit breakers, the E222 lockout device acts as a maintenance lockout on the miniature circuit breaker and engages in the space between the respective switches, thus securing the Off position.
This prevents the circuit breaker rocker switches from being accidentally moved to the On position during maintenance work.
One to two padlocks can be attached to the E222 as a safety measure, also when using the Lockout-Tagout (LoTo) principle. With the lockout device, the circuit breaker remains in the Off position until it is released again.
