The classic circuit breaker—a resettable overcurrent cutoff device—has been with us since the 1920s and is well-known for its reliable, consistent performance and a simple schematic symbol (Fig. 1).

The special device ESS20-1.. is a further extension of the product line “electronic circuit breakers”. Type ESS20-1.. has a width of only 12.5 mm and selectively protects all DC 24 V loads through a ...

Suitable for use in hazardous and non-hazardous environments, the EC-E circuit breakers selectively protect load circuits connected to a 24-Vdc power supply. The components combine active current ...

Circuit breakers are used in nearly all electrical systems — from residential dwellings to electric utility facilities. We rely on them to protect our systems from damaging overcurrents and short ...

Programmable for current rating, low-voltage threshold, circuit control, and prioritization of loads during battery backup, the ESS60-T electronic circuit breaker is said to offer unmatched load ...

DURING the continuation in February, March, and August 1928 of tests commenced in 1926 by the Circuit Breaker Research Section of the British Electrical and Allied Industries Research Association, ...

Puls has introduced a range of DIN rail electronic circuit breakers for 24V loads from 90 to 480W. “With a width of only 22.5mm, PISA-M is the smallest four-channel electronic circuit breaker in the ...
