This Phoenix Contact 0914154 is a single-pole thermomagnetic circuit breaker suitable for DIN rail mounting. It offers a robust 8A current rating and supports up to 250VAC or 65VDC.
The breaker utilizes a thermal-magnetic tripping mechanism, providing protection against overloads and short-circuit currents. The thermal part handles gradual overloads, while the magnetic part responds instantly to high current surges, tripping within milliseconds.
Typical applications for this type of circuit breaker include telecommunications systems, power supply units, industrial switchgear and control systems, and rail vehicles. Its design ensures reliable operation and protection in demanding environments.
The unit is specified with a nominal voltage of 250V AC and 65V DC, with an auxiliary circuit rating of 240V AC and 1A. It operates within an ambient temperature range of -30°C to +60°C and has a service life of 10,000 cycles at 1x IN inductive load.
