Thermal-Magnetic Circuit Breakers
Thermal-Magnetic overcurrent circuit breakers are ideally suited to protect against overcurrent and short circuit of equipment in telecommunications, process control and other industrial applications where sophisticated equipment requires a high precision performance.
A latching type bimetal is combined with a magnetic coil to ensure protection and genuine physical contact isolation. This provides the joint benefits of delayed operation for low level overcurrent protection and fast magnetic action of higher value short circuits, disconnecting the faulty circuit within milliseconds.
201
For rail mounting, low resistance option
Single pole thermal-magnetic circuit breaker with tease-free, trip-free, snap action mechanism and two button operation (M-type TM CBE to EN 60934).
Featuring a narrow profile housing, recessed terminals, standard EN rail mounting, and precision CBE performance.
2210-S2
Socket or panel mounting, single or multipole
One, two and three pole thermal-magnetic circuit breakers with trip-free mechanism and toggle actuation (S-type TM CBE to EN 60934/IEC 934).
Available with auxiliary contacts (1 x N/O, 1 x N/C) for status signalling. Two and three pole models are internally linked to ensure that both/all poles trip in the event of an overload on one pole, even if the actuator is held in the ON position
2210-T2
Rail mounting. Single or multipole
One, two and three pole thermal-magnetic circuit breakers with trip-free mechanism and toggle actuation (S-type TM CBE to EN 60934/IEC 934).
Available with auxiliary contact (1 x N/O or 1 x N/C) for status signalling. Two and three pole models are internally linked to ensure that both/all poles trip in the event of an overload on one pole, even if the actuator is held in the ON position
2215-L
Small widht, PCB or threadneck panel mounting
Miniaturised single pole thermal-magnetic circuit breakers with trip-free mechanism and toggle actuation (S-type TM CBE to EN 60934).
A separate shunt tap terminal and auxiliary contacts are available. Fast acting, medium or long delay characteristics can be specified for both models.
2215-G
Small widht. Threadneck mounting
Miniaturised single pole thermal-magnetic circuit breakers with trip-free mechanism and toggle actuation (S-type TM CBE to EN 60934).
A separate shunt tap terminal and auxiliary contacts are available. Fast acting, medium or long delay characteristics can be specified for both models.
2216-S
Small widht. With slide actuator. Plug-in mounting
E-T-A’s 2216-S is a plug-in type thermal-magnetic circuit breaker. Its small width of only 12.5 mm including auxiliary contacts makes this breaker suitable for all applications where space savings and reliable wiring are at a premium. The resettable design significantly increases system availability compared to conventional MCBs.
3300 & 3400
With auxiliary contact option. Threadneck mounting
Single pole thermal-magnetic circuit breakers with tease-free, trip-free, press-to-reset, snap action mechanism (R-type TM CBE to EN 60934; M-type with manual release (-H). Available with fast acting and standard magnetic tripping characteristics – types 3300 and 3400-
3300 Fast Acting
3400 Standard Delay
