( Brand: The Watt Stopper ), ( Manufacturer Part Number: B277E-P )
The B277E-P Stopper is a crucial electrical component designed for use in various industrial applications. This stopper is specifically engineered to meet the requirements of a 277VAC, 20A, 60Hz electrical system.
This stopper is designed to provide overload protection to the electrical circuits it is connected to. Overload protection prevents the electrical circuit from drawing excessive current, which can lead to overheating and potential damage to the equipment. The B277E-P Stopper is rated for a voltage of 277 volts Alternating Current (VAC) and can handle a current of up to 20 Amperes (A). Its operation is synchronized with the electrical frequency of 60 Hertz (Hz), ensuring it functions effectively under normal operating conditions.
The B277E-P Stopper is a reliable and robust component, suitable for use in demanding industrial environments. Its robust design allows it to withstand the rigors of continuous usage and ensure the safety and reliability of the electrical system it serves.
The stopper features a green indicator lamp that illuminates when the circuit is showing normal load current. If the circuit experiences an overload, the lamp will turn red, signaling the need for corrective actions to prevent further damage. The stopper is resettable, allowing the circuit to be restarted once the issue causing the overload has been resolved.
The B277E-P Stopper is designed with safety in mind, featuring a leakage current rating of 30 mA, ensuring it meets the standards set by Underwriters Laboratories (UL) for safe operation. Its compact and versatile design makes it a suitable replacement for various makes and models of stoppers, making it a valuable addition to any industrial electrical system inventory.
In summary, the B277E-P Stopper is an essential safety component designed for use in 277VAC, 20A, 60Hz electrical systems. Its robust design, overload protection functionality, and safety features make it a reliable and versatile solution for various industrial applications.
Buying a stopper switch, such as the B277E-P 277VAC 20A 60Hz model, can have both advantages and disadvantages for electrical applications. Here are some potential pros and cons to consider before making a purchase:
