Residual current circuit breaker IDK-40-4-300-A 40A 4-pole 300mA type A A9Z04440

Safety and reliability in your electrical installation

The Schneider Electric IDK-40-4-300-A residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. This model, with a rated current of 40A and a tripping current of 300mA, effectively reacts to both sinusoidal and pulsed currents, minimizing the risk of electric shock and damage to equipment. The four-pole design makes it ideal for protecting circuits in residential and commercial buildings.

Installation and functionality for professionals

Mounting on a DIN rail (width 4 modules) is quick and intuitive. The circuit breaker is characterized by a high short-circuit strength (10kA), which guarantees its reliable operation even in difficult conditions. The cross-section of the connectable solid conductors up to 35mm² and stranded conductors up to 25mm² provides flexibility in cable selection. The placement of the N conductor on the left side facilitates busbar connection with overcurrent circuit breakers – a solution appreciated by installers. Additionally, the ability to test the correct operation using the "T" button (once every six months for the first 7 years of use) allows for regular monitoring of the device's condition.

Key features and benefits:

• Protection against electric shock: Provides effective protection against electric shock thanks to a 300mA tripping current and type A characteristic.
• Versatile application: Suitable for operation in AC networks with a voltage of 400V and a frequency of 50/60Hz.
• High resistance: Short-circuit strength of 10kA guarantees stable operation even during overloads.
• Easy installation: Quick mounting on a DIN rail – only 4 modules wide.
• Convenient testing: Possibility of testing functionality using the "T" button.
• Optimized busbar connection: N conductor placed on the left side facilitates cooperation with overcurrent circuit breakers.
• Wide operating temperature range: Trouble-free operation in a temperature range from -25°C to +40°C.
• Safety confirmed by standards: Compliance with relevant standards ensures a high level of safety (rated impulse withstand voltage Uimp: 4 kV).

The IDK-40-4-300-A residual current circuit breaker is a solid and reliable solution for anyone who cares about the safety of their electrical installation and user comfort. Its versatility and ease of installation make it an ideal choice for both professional installers and demanding end-users.
