Vario Metallic Enclosed Switches
Vario switches meet UL508 requirements as both enclosed and open manual motor
controllers. They are also marked “Suitable as Motor Disconnect” allowing installation on
the load side of the motor branch circuit short-circuit and ground-fault protection. If motor
branch circuit short-circuit and ground-fault protection is needed, use a GS1 or 9422
fusible switch or circuit breaker meeting NEC 430.52 requirements.
