They provide excellent protection of hermetically sealed compressors and artificially cooled motors which require ambient insensitivity and quick trip response times. Combined with a series lockout relay, they can provide unsurpassed protection for hermetically sealed compressor motors in air conditioning applications. The combination of high trip speed, current adjustment, and ease of installation makes it suitable for these applications. The trip curves have been custom tailored to provide proper overload protection on such loads without nuisance tripping. Features The overload provides phase loss protection for the motor by tripping in three seconds upon complete loss of one phase of a three phase motor branch circuit. The heaterless construction of these overloads minimizes energy costs and the costs of cabinet ventilation or cooling. While thermal overloads require a heater selection based on a relatively wide range, these overloads have many clicks covering the same ampere range (see Figure 1 below). Each overload has a 4:1 or 2:1 current adjustment range with the adjustment dial reading out must hold amps. Must trip amps are 112% of the must hold setting. In addition to the markings on the dial there are audible clicks which allow for extremely fine tuning. Figure 1 A1 Frame 958 Series B Frame 958 Series RSP-PRC003-EN 49
