Hydraulic-Magnetic and Magnetic Overcurrent Circuit Breakers

Typical Applications

E-T-A hydraulic-magnetic and magnetic overcurrent circuit breakers are ideally suited to protect against overcurrent and short circuit of printed circuit boards, semi-conductors and telecommunications equipment.


Circuit breakers with magnetic or hydraulic-magnetic trip mechanism respond extremely fast and provide genuine physical contact isolation. Magnetic trip ensures disconnection of the faulty circuit nearly without delay in the event of short circuit, but also in the event of low overloads. Our models also provide hydraulically delayed switching characteristic required for certain applications.
