Description

When selecting a circuit breaker for industrial or commercial applications, understanding the technical specifications is crucial. This robust device is engineered to meet rigorous standards and ensure reliable performance under demanding conditions. With a rated current of 32 A, it efficiently manages electrical flow, safeguarding your systems from overcurrent situations. The breaker boasts a rated impulse withstand voltage of 4 kV and an insulation voltage of 440 V, indicating its capacity to handle voltage spikes without compromising safety or efficiency. Its rated operational voltage stands at 400 V, making it suitable for numerous commercial power setups. A key feature is its breaking capacity of 11.3 kA, which ensures that the breaker can interrupt fault currents effectively, providing essential protection in case of short circuits or overloads. The unit's power loss is limited to just 10.8 W, reflecting its efficient design aimed at minimizing energy wastage while maintaining optimal performance. This model features three poles and adheres to the IEC/EN 60947-2 standards, confirming its compliance with international safety and quality benchmarks. The IP20 degree of protection indicates that it guards against solid objects larger than 12 mm but should be installed in environments where exposure to moisture isn't a concern. The terminal type is screw clamp with a tightening torque requirement of 2.8 N-m ensuring secure connections during installation. Dimensions are compact with a width of 52.5 mm, height of 88 mm, and depth of 69 mm allowing for easy integration into existing panels without requiring excessive space. Designed for versatility across various climates, this breaker operates efficiently within ambient temperatures ranging from -25°C to +55°C and can be stored safely between -40°C and +70°C without degradation in performance or reliability. The housing comes in RAL 7035 grey which not only provides an aesthetically neutral appearance suitable for most settings but also aligns with industry-standard color codes aiding quick visual identification in complex installations. Its Curve Type K characteristic makes it ideal for protecting circuits with high inductive loads such as motors or transformers by allowing temporary surges while still providing rapid response when necessary faults occur. Overall this circuit breaker offers dependable protection tailored to suit diverse application needs ensuring peace of mind through consistent operation backed by rigorous standards compliance all encapsulated within durable construction designed for long-term use across varied environmental conditions.
