Description

Brand Name

O-Z/Gedney

Type

Unidirectional

Description

O-Z/Gedney Class 530 inertia switches are unidirectional shut down devices that operate upon sharp impact and provide protection for oil well pumping units. When installed properly, the switch will shut down the pump engine or motor upon impact occurring from sucker rod breakage. An external adjustment screw varies the impact trip level of the switch. The desired setting should prevent tripping on startup and normal operation, but trip upon malfunction.
