A leading manufacturer of True RMS electronic trip devices and
trip unit conversion kits for power circuit breakers. |
|||||
| Utility Relay Company is a leading manufacturer of microcontroller based, true RMS solid state trip units for AC and DC power circuit breakers. The AC-PRO trip unit is designed for 600v class air circuit breakers. The ZERO-Hertz trip unit is designed for DC power circuit breakers and FKB traction power circuit breakers in the transportation industry.
URC trip units retrofit conversion kits replace aging electro-mechanical series overload trip devices, thermal magnetic overcurrent realeases, and older style electronic trip devices to provide greater accuracy, reliability, functionality and life extension of older circuit breakers at a fraction of the cost of a new circuit breaker without changing out the switchgear. Utility Relay can provide complete conversion retrofit kits for hundreds of existing power circuit breaker types from different manufacturers such as GE, Westinghouse, ITE, ABB, Brown Boveri & CIE, Siemens, Allis Chalmers, Federal Pacific, Federal Pioneer (FPE), Sylvania, Unilec, Mears, Square D, Roller Smith, Englich Electric, Whipp & Bourne and others. |
