The Siemens CQD270 is specifically engineered as a thermal magnetic circuit breaker. It boasts a rated current capacity of 70 A and operates optimally at a voltage level of 480 VAC. This unit integrates seamlessly into 1-phase electrical systems and features two poles for effective circuit management.
Equipped with a magnetic contactor, the CQD270 ensures reliable protection against electrical faults. It is defined by thermal magnetic protection, which allows the breaker to respond adequately under both overload conditions and short circuits. The breaker features long-time and instantaneous trip settings, which means it can handle both prolonged overload situations and sudden spikes in current.
The connection type used is a feed-thru setup, making installation straightforward and efficient. With an AIC rating of 14 kA at 480 V, the CQD270 is engineered to interrupt fault currents effectively, providing a safeguard against equipment damage. This model operates reliably in humid conditions, capable of functioning at levels up to 80% relative humidity without condensation, making it a solid choice for diverse applications in varied environments.
