Modular disconnecting switch 3P 63A 400VAC SBN363

Modular isolating switch – safety and reliability in one

This 3-pole isolating switch with a rated current of 63A is a key element of any electrical installation, providing effective circuit disconnection and protection against overloads and short circuits. The device is designed to disconnect circuits under load, as well as to safely isolate during maintenance or repairs. Thanks to its compact size (3 modules wide), it is ideal for switchboards with limited space.

Construction features and application

The SBN363 isolating switch from Hager has been designed with ease of mounting on a DIN rail in mind. Its solid construction guarantees long-lasting and trouble-free operation. The device finds application both in domestic and industrial installations where reliable disconnection of the electrical circuit is required. It meets the standards PN-EN 60943-3 and PN-EN 60669-1, which confirms its compliance with applicable safety standards.

Advantages and benefits for the installer and user

• Safety: Provides effective circuit isolation, minimizing the risk of electric shock during maintenance work.
• Reliability: Solid construction and high quality workmanship guarantee long-term operation without failure.
• Compact dimensions: Occupies only 3 modules in the switchboard, saving valuable space.
• Easy installation: Quick and easy mounting on a DIN rail facilitates installation and reduces working time.
• Compliance with standards: Meets the requirements of standards PN-EN 60943-3 and PN-EN 60669-1, ensuring safe use.
• Versatility: Suitable for use in both domestic and industrial installations.
• Durability: Rated switching capacity of 1,332 kA provides resistance to short circuits.
• Durability: Short-circuit withstand strength (Icw) is 0.945 kA, confirming its resistance to surge currents.

Technical parameters in practice

The switch is characterized by a rated voltage of 400V AC and a rated current of 63A, making it suitable for most standard electrical installations. The IP20 degree of protection provides protection against finger contact, but does not protect against the action of water. The installation depth of 68 mm allows for easy adaptation to different types of switchboards. The lack of normally open and changeover contacts means that the device only functions as an isolating switch – it is not used to switch circuits.
