3-pole isolating switch 63 A in OB4 with universal front RSI-3063\OB4

Isolating switch – safety and reliability in your installation

This three-pole isolating switch with a rated current of 63 A, mounted on a TH35 (OB4) rail, is a key element ensuring the safe and efficient operation of the electrical installation. Designed for both domestic and industrial applications, it guarantees effective disconnection of the circuit in emergency situations, during maintenance or repairs. Its versatility makes it an ideal choice for both professional installers and demanding users.

Functionality and technical parameters

This switch acts as an emergency switch and a main disconnecting switch, allowing for quick and safe disconnection of power when needed. The rated operating voltage of 400 V ensures compatibility with most standard electrical installations. The IP20 protection class protects against accidental contact, increasing safety. The design with a universal RSI-30 front allows for easy integration with various control and signaling systems.

• Rated continuous current: 63 A – ensures safe operation of circuits with high loads.
• Rated operating voltage: 400 V – compatibility with most installations.
• Protection class (IP): IP20 – protection against accidental contact.
• Function: Emergency switch and main disconnecting switch – versatile application.
• Mounting: TH35 (OB4) rail – quick and easy mounting in the distribution board.
• Cross-section of connection cables: 6...16 mm² (rigid) - allows connection of cables of different thicknesses.

Additionally, the switch is characterized by high mechanical strength (10,000 cycles) and switching strength (1500 cycles), which guarantees long-lasting and reliable operation. Short-circuit capacity up to 10 kA (with gG 63 A fuse) provides effective protection against the effects of short circuits. The rated short-time withstand current Icw(1s) is 1.8 kA, and the let-through short-circuit current Icm is as much as 6 kA, which confirms its solidity and reliability in difficult working conditions.
