Hydraulic-Magnetic & Magnetic Overcurrent Circuit Breakers
Hydraulic-Magnetic & 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. E-T-A’s models also provide hydraulically delayed switching characteristic required for certain applications.

Single pole purely magnetic circuit breaker
Single pole miniaturised magnetic circuit breakers with unique high-speed operating mechanism and push/pull on/off manual actuation. Fitted with electrically separate excitation and switching circuits, and one pair of auxiliary contacts which close when the main circuit is open. Also suitable for impulse operation.
8335
Well-priced design
Single and multipole magnetic circuit breakers with trip-free mechanism and toggle actuation. A choice of fast magnetic or hydraulically delayed switching characteristics (S-type MO or HM CBE to EN 60934) ensures suitability for a wide range of applications. Industry standard dimensions and panel mounting. Options include auxiliary changeover contacts. Low temperature sensitivity at rated load.
Approved to CBE standard IEC/EN 60934 S-type HM CBE.
8340-G2
Push-pull actuation, threadneck panel mounting
Single, two and three pole magnetic circuit breakers with trip-free mechanism and push/pull on/off manual actuation. A choice of fast magnetic only or hydraulically delayed switching characteristics (Stype MO or HM CBE to EN 60934) ensures suitability for a wide range of applications. Convenient threadneck panel or plug-in mounting, and with a white push button indicator band showing clearly the tripped/off position.
Approved to CBE standard EN 60934 (IEC 60934).
