8340-F410-P1M1-A3H0-25A, 8340 series 1P magnetic C
|4 550||×||=||4 550|
Single pole magnetic hydraulic CBE with trip free snap action mechanism with toggle actuation.
Industry standard dimensions with medium delay for most applications.
Typically used on control equipment, communication systems, transportation (rail) and power supplies.
Can be used as DC curve circuit breaker up to 80 Vdc
IEC classification S/HM
These CBE's are designed specifically for equipment/systems and should not be confused with large MCB's intended to protect distribution wiring against catastrophic faults.
Термомагнитные, обратимые Thermal Magnetic Convertible
All CBEs have blade terminals and have an insulation resistance greater than 100MΩ (MegaOhms).
|IEC 934 (BS/EN 60 934) definitions|
IEC requirements to equipment over-current contact breakers, in which complete short circuit either cannot occur or is limited by back-up protection somewhere else in the system.
Equipment contact breakers are divided into three main types:
|RS type - that automatically switches off if there are overloads that require manual reset.|
M type - functions as above, but can occasionally be used for manual shut down; is however not intended to function as a normal switch in daily use.
S type - combines overload protection with the opportunity for use as a normal on/off switch under normal load conditions.
Each of the above types has a sub-set with the following trigger methods:
TO - Thermal only. Sensitive to the heating effect of an over-current, because it uses a bi-metal or similar element as a contact breaker.
TM - Thermo-magnetic. A magnetic solenoid in series with a thermal element provides a more rapid response to a large fault current.
MO - Magnetic only. Triggers immediately when an overload is registered.
HM - Hydraulically dampened magnetic. Provides a long range of characteristics for delayed triggering and is mainly insensitive to changes in ambient temperature.
EH - Electronic hybrid. Combines solid state registration of overloads with physical circuit breaking.
