Residual current circuit breaker iID-40-4-300-AC 40A 4-pole 300mA type AC A9Z14440

Residual Current Device (RCD) iID-40-4-300-AC is a four-pole protection device, designed to protect people and electrical installations from the effects of earth leakage currents. The device with a rated current of 40A and a tripping current of 300mA (AC type) is used in residential, commercial and industrial installations. Manufactured by Schneider Electric, model A9Z14440 is characterized by high reliability and easy mounting on a DIN rail.

The design of the RCD has been carefully thought out for the comfort of both installers and end-users. Double terminals allow connection of wires with different cross-sections, making it easier to adapt to existing installations. The Visi-Trip optical indicator signals the tripping of the RCD, and the ability to remove a single device without removing the entire busbar significantly speeds up service work. Additionally, the RCD has a padlock for increased safety.

This model also stands out for its compliance with two standards – EN/IEC 60 898 and EN/IEC 60 947-2, which confirms its versatility. The short-circuit capacity of the device (10kA) is sufficient in most applications, eliminating the need for additional fuse links. VisiSafe and VisiTrip indicators allow for quick identification of the device status and location of any fault, which translates to shorter repair times and minimized downtime. The RCD also has an N conductor located on the left side, making it easier to synchronize with overcurrent circuit breakers.

Key features:

• High reliability: Provided by a renowned manufacturer – Schneider Electric.
• Versatility: Compliance with EN/IEC 60 898 and EN/IEC 60 947-2 standards enables wide application.
• Easy installation and servicing: Double terminals, removal without removing the busbar and padlock are conveniences for installers.
• Quick diagnostics: VisiSafe and VisiTrip indicators facilitate identification of the device status and location of faults.
• Safety: Protection against electric shock thanks to a tripping current of 300mA (AC type).
• Durable construction: Made of high-quality materials resistant to environmental conditions (operating temperature: -5 to 60°C).
• Compact dimensions: Width of 4 modules allows for efficient use of space in the switchboard.

The iID-40-4-300-AC RCD is a solid and functional solution for demanding electrical installations, guaranteeing safety and comfort of use.
