Electrical locking devices
Electrical lockouts are used for isolating electrical energy sources during lockout-tagout and prevent an accidental restart. Lockout-Tagout-Shop offers a wide range of lock-out devices for different types of circuit breakers, insulation plugs, plugs and push-buttons.
Electrical interlocks are available for the following electrical isolation points:
- Circuit breakers pin-in
- Circuit breakers pin-out
- Circuit breakers without pin
- Oversized circuit breakers
- Motor circuit breakers (starter motors)
- Toggle switches
- Screw fuses (E27, E33, E14, E16, E18)
- Blade fuses (NH fuses)
- Wall switches
- Industrial plugs
- Emergency stop
- Control consoles
Electrical interlocks that do not isolate the main power, but only the control current are officially not lockout-tagout interlocks. This is because the locking of control currents fall under the rules of the machinery directive. This especially applies to pushbutton and emergency stop locks.
Electrical interlocks are for the most part made of non-conductive materials and should be secured with a non-conductive safety padlock, preferably a lock with a non-conductive plastic shackle.
These days there are many universal lockouts on the market for circuit breaker lockouts. That is why the number of different lockouts for electrical hazards can be significantly reduced.
