Description

Top-Rated Safety Switches & Disconnect Switches From PSI Power & Controls

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 Power & Controls are available in standardized amperage ratings from 30-2000 amps as per your needs and can be situated for both fusible switches 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 switch 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.

Product Usage

Uses of Our Safety Switches & Disconnect Switches

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 employees & 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.

Safety 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 disconnect 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 safety switch or disconnect switch for your needs, the PSI Power & Controls team is always glad to assist.
