Modular switch I-O-II 4P 100A HI405R

Modular switch for demanding applications

A 4-pole modular switch with a rated current of 100A is a reliable solution for switching circuits in electrical installations. Designed for use in both commercial and industrial buildings, it provides safe and efficient power switching. Its design allows it to be used as a safety disconnect switch, a maintenance disconnect switch, and a main disconnect switch, making it a versatile element of any installation.

Functionality and application

This switch, thanks to the ability to switch in I-O-II configuration, is ideal for situations requiring a choice of power source or disconnection of the load from the network. The possibility of using it as a transfer switch increases its usefulness in uninterruptible power supply (UPS) systems or when switching between two independent energy sources. A solid screw connection ensures a secure and durable connection of the wires, and the possibility of mounting on a plate and in distribution boards facilitates integration with existing infrastructure. Use in distribution boards is confirmed by the manufacturer.

Characteristics and benefits

• Versatility: The I-O-II switch function allows flexible adaptation to different installation needs – from simple selection of a power source to advanced redundancy systems.
• Safety: Meets the requirements for safety and isolating disconnect switches, providing protection against electric shock and equipment damage. A locking mechanism further protects against accidental switching.
• High performance: Rated power up to 51 kW (AC-3) and 28 kW (AC-23) allows operation of even demanding loads. Rated continuous current at 100A guarantees stable system operation.
• Durability: Made of high-quality materials, resistant to mechanical damage and environmental conditions. The construction of the device as a permanently mounted element ensures long-term reliability.
• Easy installation: Compatible with modular mounting systems, which simplifies and speeds up installation.
• Short-circuit protection: Rated short-time withstand current Icw is 2.5 kA, which provides effective protection of the installation in the event of a short circuit.
• Wide range of operating voltages: Designed to operate in networks with a voltage from 380 to 690 V AC, which increases its versatility.
• Mechanical strength: Designed for frequent switching thanks to the solid mechanical construction and high-quality materials used for the production of actuators (short rotary handle).
