Ambient Operation
Operates normally in temperatures between –40° C and +85°C.
Insulation Resistance
Not less than 100 megohms at 500Vdc.
Dielectric Strength
Withstands 1500 volts, 60Hz for 60 seconds or 1800Vac for one second between all electrically isolated terminals.
Endurance
Mechanical life in excess of 50,000 operations. In manyapplications, however, contact wear due to the electrical load determines unit life. At
maximum electrical ratings, the SNAPAK® can perform 10,000 operations at rated current and voltage. Under UL 1077, the SNAPAK® can perform
50 operations at 150% of maximum rated current followed by 6,000 operations at maximum rated current. Under EN60934 the SNAPAK® can
perform 6,000 electrical operations. After any endurance cycle, the breaker will calibrate and have working
