Residual current circuit breaker for DPX 026088

Residual Current Device (RCD) for DPX – reliable installation protection

This RCD, designed to work with DPX circuit breakers, is a key element ensuring safety in electrical installations. It provides protection against the effects of short circuits and earth leakage currents, minimizing the risk of electric shock and equipment damage. This is particularly important in three-phase circuits, where the risk of such situations is higher.

Functionality and installation

The RCD is designed for mounting on a TH35 rail, making it easy to integrate with existing electrical infrastructure. It has screw connections, guaranteeing secure and durable wire connections. The lack of detachable terminals increases connection reliability and minimizes the risk of accidental disconnection. The differential current indicator allows for quick identification of potential problems in the installation. The fault memory function facilitates diagnosing the causes of outages, which is particularly useful when servicing installations.

Operating characteristics and parameters

The RCD operates in a supply voltage range of 195.5 – 253 V at a frequency of 47-63 Hz, ensuring its compatibility with most standard electrical networks. The adjustable differential current setting range (30 – 30000 mA) allows you to adapt the device's sensitivity to the specifics of the protected installation. The minimum time delay on power-up is 5 seconds, which prevents unnecessary shutdowns caused by short-term voltage surges. Compact dimensions (width 35 mm, height 89 mm, depth 65.6 mm) allow for easy placement in a distribution board.
