ABB Emax Circuit Breaker

Emax 2 E1.2 is ABB’s most compact air circuit breaker (ACB) for low-voltage switchboards where footprint and performance both matter. In the IEC range, E1.2 reaches up to 1600 A with breaking capacity up to 66 kA and short-time withstand 50 kA/1s; in the UL/ANSI range, it reaches up to 1200 A with typical ~65 kA interrupting capability—choose per market and standard. Trip options include Ekip Dip/Touch/Hi-Touch/G to implement LS/I, LSI, LSIG protections and advanced energy functions. Mounting can be fixed or withdrawable with accessories such as rotary handles, motor operators, aux contacts, shunt/undervoltage releases and front terminals; configuration and accessory set are common across the Emax 2 family.
