Klixon® 2EP Series Thermal Circuit Breakers
1 to 35 Amp, Commercial, Explosion-proof

Overview Data Sheet (PDF) Request Pricing or Info

The 2EP Series is a sub-miniature push-pull thermal circuit breaker adapted from a proven aerospace circuit breaker design to offer a truly high performance solution to the market place at a competitive price.  The push-pull design of the 2EP decreases the risk of accidental tripping; temperature compensation allows it to maintain a constant calibration across temperature extremes; the thermal design allows a sufficient delay to minimize nuisance trips; the robust latching design offers high shock and vibration performance; the multi break design offers high interrupt performance and ratings at both AC and DC voltages.  The 2EP is U.L. recognized (1077) and rated to 75 VDC, and 250 VAC at 60 Hz.  All these features combine to make a solution which is ideally suited for industrial equipment, radars, medical and dental equipment, electronic control systems, recreational vehicles, telecom equipment, power supplies, and test equipment, to name a few.
