Hydraulic Magnetic Miniature Circuit Breakers (MCB

E-T-A’s 4231 series is a hydraulic-magnetic MCB for hazardous locations where combustible materials are present, and high voltage equipment protection is required. The series meets safety standards in accordance with UL1077, CSA22.2, and UL Class I Division 2, Groups A, B, C, and D. The hydraulic-magnetic MCB's trip mechanism can respond extremely fast and provides genuine physical contact isolation. The magnetic trip ensures disconnection of the faulty circuit in the event of short circuit nearly without delay, but also in the event of low overloads.
