Technical details:
Manufacturer: Hager
Model: CJG444D
Product type: FI circuit breaker (residual current circuit breaker)
Number of poles: 4-pole – ideal for protecting three-phase circuits (three-phase current)
Rated current (In): 40 A – suitable for installations with higher power requirements
Fault current (IΔn): 100 mA – medium sensitivity for extended protection in industrial applications or as fire protection
Protection type: Type A – detects both sinusoidal alternating currents and pulsating direct residual currents
Short-circuit strength: 10 kA – high resistance to short-circuit currents, ideal for demanding installations
Power supply: 400 V AC – suitable for three-phase AC networks
Mounting type: DIN rail – easy installation in distribution cabinets and control cabinets
Operating temperature range: -25°C to +40°C – reliable operation even under difficult environmental conditions
Protection class: IP20 – protection against contact and foreign bodies, suitable for use in dry indoor areas
Special features:
Extended residual current protection: With a tripping threshold of 100 mA, this residual current device offers additional protection, especially in environments where a higher residual current is permitted, such as in industrial plants or special applications where fire protection is a priority.
Type A detection: The CJG444D detects both sinusoidal alternating currents and pulsating direct residual currents, thus offering optimal protection even for modern systems with frequency-controlled devices or electronic loads.
High short-circuit resistance: The residual current device is designed for a short-circuit resistance of up to 10 kA, which makes it particularly robust against high short-circuit currents and further increases the safety of the system.
Reliable and robust design: The circuit breaker is durable and reliable, even under regular load. The precise switching and high-quality mechanics ensure safe operation and minimize maintenance requirements.
Easy to use: The clear labeling and robust lever mechanism enable intuitive and safe operation and installation.
Scope:
The Hager CJG444D residual current device is ideal for use in demanding electrical installations, such as workshops, industrial areas, and larger commercial properties. Thanks to its 100 mA tripping threshold, it can also be used as additional fire protection, for example, in areas with an increased fire risk. The device not only protects against dangerous residual currents but also increases the overall safety of the installation.
With the Hager CJG444D, you're relying on a high-performance safety product that meets the highest requirements in demanding environments. A high-quality residual current device that comprehensively protects your electrical installations and offers you reliable safety.
