Fusible and non-fusible units are in stock in a variety of enclosure sizes and configurations.
Disconnect switches are used to close, open, or change in some fashion the connections in a circuit or electrical system for the purpose of isolating power. Electrical safety disconnects do not have a current interrupt rating and are intended to be used once the circuit has been opened by a circuit breaker. Bay Breakers Online supplies all kinds of high performance electrical supplies including Siemens, General Electric, and Cutler Hammer safety switches, circuit breakers, motor starters, and air circuit breakers for a host of demanding applications.
Safety disconnects are essential components for just about any application where electrical power has the potential to cause injury to people or equipment. Disconnect switches are also needed to isolate power supplies when maintenance is needed. In general, a safety disconnect is an automatic or manual electric switch that disconnects one circuit from another to protect against power surges that can occur for many reasons, such as lightning strikes or voltage spikes.
Mechanical safety interlock switches are another important type of industrial safety device. These switches create an interaction between a guard door and a potentially hazardous power source. When the safety interlock opens the guard door, power isolation occurs and the operator can safely access the system. Bay Breakers Online serves up a full menu of safety disconnects and other electrical components for convenient and affordable one-stop shopping.
Most disconnect switches feature manually-operated external handles for breaking the circuit between the power source and the machine or electrical system. The disconnect handle, switch, or button is typically bright red common to emergency or safety devices.
Often disconnect switches are used to switch transformer magnetizing current, parallel load currents, and cable charging or level line current. Medium-duty safety disconnects are used in applications of power generation, transmission, and distribution. DC battery disconnects are bidirectional and can either open or close the flow of current from the battery to the electrical system or machine. AC disconnect safety switches are used to isolate power from air conditioning condensers.
Manual safety switches are required by the National Electric Code to be easily visible near electrical equipment such as motors, compressors, motor control centers, and industrial drives. A typical disconnect switch assembly consists of components including the switch mechanism, an enclosure, and variations of grounding, connecting, and mounting hardware. Disconnect models are in stock in a plethora of configurations for electrical protection in every environment involving every type of power supply, equipment type, and industry standard.
