Residual current circuit breaker IDK-63-4-30-AC 63A 4-pole 30mA type AC A9Z05463

4-pole Residual Current Circuit Breaker (RCCB) with a rated current of 63A and a tripping current of 30mA, type AC, is a key element ensuring safety in electrical installations. The device effectively protects against electric shock by reacting to leakage currents to earth. It is indispensable both in residential and commercial buildings where high reliability and personal protection are required.

Features and Application

This model, catalog number A9Z05463, is distinguished by its solid construction and easy mounting on a DIN rail. Its 4-pole design allows protection of the entire circuit, and type AC ensures a correct reaction to sinusoidal currents – typical of most electrical devices. The circuit breaker is characterized by a high surge current resistance (0.25 kA) and the ability to withstand impulse voltage up to 4 kV, guaranteeing its reliable operation even in difficult conditions.

The application of this circuit breaker includes protection of circuits with conductor cross-sections from 1 mm² to 35 mm² (solid core) and from 1 mm² to 25 mm² (stranded). This allows it to be adapted to various electrical installations. Additionally, the presence of dual terminals from below (busbar + wire) and serrated terminals facilitates and speeds up the connection process, increasing connection reliability.

Advantages and Technical Parameters

The IDK-63-4-30-AC circuit breaker offers a number of benefits for installers and end-users:

• High reliability: Rated differential current of 0.03 A ensures effective protection against electric shock.
• Easy installation: Mounting on a DIN rail and dual terminals from below significantly simplify installation.
• Secure connection: Serrated terminals minimize the risk of wire loosening.
• Status control: The ability to check the correct operation with the "T" control button (once every six months for the first 7 years of use) allows for regular verification of the device's condition.
• Optimal busbar arrangement: Placement of the N conductor on the left side facilitates busbar arrangement with overcurrent circuit breakers, improving organization in the distribution board.
• Wide operating temperature range: The device maintains its properties in a temperature range from -5°C to 40°C.
• Compliance with standards: Meets safety requirements confirmed by the CE marking.

Additional information: the width of the circuit breaker is 4 modules, and the installation depth is 44 mm. Power losses are 5.6 W at a frequency of 50/60 Hz, and the degree of protection is IP20 – provides protection against touching with a finger and solid objects larger than 12.5 mm. Short-circuit strength (Icw) is as high as 10 kA, which demonstrates the high resistance of the device to overloads.
