MOLDED CASE CIRCUIT BREAKERS, BUYLOG SECTION 6

— Industrial Circuit Breakers 15-100A Thermal Magnetic Trip Type TEY/TEYF Noninterchangeable Trip Bolt-on 480Y/277V Class

TEY and TEYF breakers are one-inch wide per pole, compact, bolt-on circuit breakers for use on grounded 480Y/277 Vac systems. Short circuit ratings at that voltage for TEY and TEYF are 14 and 18kA, respectively. TEYF also offers higher selectivity ratings with upstream devices (See DET-537 for details). The bolt-on mounting base (TEY3B) shown on page 6-177 makes TEY and TEYF suitable for various lug-lug applications.
