4-pole isolator switch 125 A in a large polycarbonate housing RSI-4125\OBP\D RSI-4125\OBP/D

Disconnect switch – reliable power disconnection

This four-pole disconnect switch with a rated current of 125 A is a robust solution for safely disconnecting electrical circuits. It is suitable for both industrial installations and public buildings, as well as homes – anywhere where a certain and visible power cut-off is required. Made of high-quality materials, it ensures long-lasting and trouble-free operation.

Design and application

The RSI-4125\OBP/D disconnect switch has been designed with safety and functionality in mind. The housing made of durable polycarbonate protects the internal components from mechanical damage and weather conditions. The IP20 protection class provides protection against finger contact, which is particularly important in high-traffic areas. The device will be perfect as an emergency switch or main disconnect switch in the circuit.

Key features and benefits

• High mechanical resistance: Polycarbonate housing guarantees durability even in harsh working conditions.
• Safety of use: IP20 protection class minimizes the risk of electric shock.
• Versatility: Can function as an emergency switch or main disconnect switch.
• Adapted to high loads: Rated continuous current of 25 A and switching current of 125 A (AC-21A, AC-22A) allow for servicing demanding circuits.
• Wide voltage range: Designed to operate in networks with a voltage of 400 V.
• Durability: Withstands thousands of mechanical and switching cycles – 8000 mechanical cycles and 1000 switching cycles.
• Resistance to external factors: Meets the requirements for resistance to vibrations, shocks and cyclic damp heat (according to IEC standards).

Operating parameters and installation

The disconnect switch is designed for mounting on a rail or directly on the surface. Connection cables with a cross-section of 25 to 70 mm² (rigid) provide installation flexibility. Remember to observe appropriate safety rules during installation and operation of the device. In the event of a short circuit, the disconnect switch will withstand a short-circuit current of up to 25 kA (with a gL/gG 125 A fuse).
