Description
| Ericson Mechanical Interlocks combine
a disconnect switch and receptacle into one device that eliminates
the making and breaking of plug and receptacle under load. The safety
mechanism within the enclosure prevents the switch from being turned
to the “ON” position until the plug is fully inserted
into the receptacle. Once fully engaged, the plug is locked into
place when the switch is turned on and cannot be removed until the
switch is turned to the“OFF” position. This prevents
making or breaking the circuit under load. Ericson mechanical interlocks
are also available with optional circuit breaker. |
