Fusible and Non-Fusible Safety Switch / Disconnect NEMA 4 and NEMA 4X
Safety switches are ideal for providing a swift means of disconnecting mechanical or electronic systems from their primary power source in a safe manner. Safety switches operate both automatically, protecting against circuit faults, and manually in the case of a needed emergency stop or for planned maintenance and repairs.
Switches offered by PSI Control Solutions are available in standardized amperage ratings from 30-1200 as per your needs and can be situated for both fusible and non-fusible applications. Neutral bar-required and not required are also available as options for custom fabrication.
The switch is housed in a NEMA enclosure rated NEMA 4, for indoor/outdoor use that protects against solid objects and water intrusion, and NEMA 4X, with similar ratings with added resistance to corrosion and corrosives.
Safety switch and safety disconnect products from PSI are suitable for most broad and special use applications in industrial and commercial sectors including manufacturing facilities, warehouses, healthcare and ambulatory care, banks, gas stations and fuel centers, retail, and more.
The use of safety switches provides a cost-efficient means of providing higher degrees of safety both for the integrity of products with which they are used, and more importantly, the safety of personnel. If a fault is detected by the switch—overloading, short-circuiting, etc.—the switch will disengage the machine or appliance from its power source within milliseconds.
Switches can also be used manually, making them an ideal option for faster and more efficient machine maintenance and repairs, as well as adding a further degree of protection in the event an emergency machine stop becomes necessary. Our safety switches are designed to save lives and detect the loss of current from a circuit and cut power in milliseconds.
Both fusible and non-fusible switch options are generally equally effective, but many NEC requirements and product manuals may stipulate the specific use of one or the other, so it is advised that you follow your owner’s manual closely to make the right choice. Should you need guidance or assistance in choosing the correct switch for your needs, the PSI Control Solutions team is always glad to assist.
