Enclosed custom circuit breakers offered by PSI Control Solutions are ideal for protecting circuits, equipment, and personnel from potential electrical hazards caused by overloading and short-circuiting. When an electrical current would exceed the designated safe quantity, your enclosed breaker will break electrical connection and halt the current within a fraction of a second, providing ideal means of safe and sure disconnect.
The product is available in NEMA 4X 316 stainless steel and special NEMA 4/12. Both offered enclosure types are rated for indoor or outdoor use, and are effective in protecting the circuit breakers from rain, directed water spray, snow and ice formation, and dirt or other common small particle matter ingress. Manual direct disconnect handle options are available as a rotary switch through the door or flange flex shaft.
Amperage ratings available include ranges starting at 200 and reaching ranges as high as 2000. For applications in excess of 1000 amps (rated at a standard 480v), please contact PSI Control Solutions directly for a custom ground fault relay. Circuit interrupting capacities offered by this product include kAIC (thousand ampere interrupting capacity) at 35kAIC, 65kAIC, and 100kAIC. Available breaker percentage ratings include standard 100% and NEC-mandated 80% in accordance with your application and needs.
Our enclosed circuit breakers offer customers all the benefits and flexibility inherent in a traditional custom built circuit breaker, packaged in a flexible configuration compatible with most applications requiring a safe means of disconnect. Common applications include surge protection, management of backup generators, circuit protection when using alternative energy, motor controls, and general ease-of-use in disconnection.
Enclosed circuit breakers and the associated electrical systems into which they’re installed should be installed and maintained with utmost caution by experienced professionals. Make sure anyone interacting with your system is thoroughly apprised of the components in the system and familiar with the manufacturer provided documentation on safety and operation. Current and potential future applications should be considered during the installation process, to avoid creating problems when adding later components to your electrical system.
To achieve optimal performance from your enclosed circuit breaker, make sure you match the needs of your system accurately to your circuit breaker. A mismatch between system requirements and your breaker can result in high levels of inefficiency, early degradation of system components, and other forms of waste, even in cases where the problem does not create a safety hazard. Regular checkups and maintenance of worn or oxidized components can additionally improve the efficiency and safety of your system, preventing early wear or wasted power over time.
In addition to custom products like our enclosed circuit breakers, PSI Control Solutions offers a range of accessories and effective supplementary products in order to fully meet the needs of our clients. Offered accessories for this product include:
