Power switch I-0-II 4P 400A HI456

Power switch I-0-II – reliable switching in your installation

This four-pole power switch with a current of 400A is a solid solution for switching circuits in power distribution systems. It enables safe and efficient switching between power sources, e.g. the grid and a generator, which is crucial for ensuring uninterrupted power supply. The switch design allows it to be used as a main switch, safety switch and maintenance switch, making it a versatile element of any electrical installation.

Functionality and application

The HI456 switch finds application in a wide range of electrical installations, both in commercial and industrial buildings. It is ideal for applications where reliability and the ability to quickly switch power in the event of a failure or the need to perform maintenance work are required. Thanks to the possibility of mounting on a plate or in distribution boards, it can be easily integrated with the existing infrastructure. The locking mechanism provides additional safety, preventing accidental switching.

Advantages and benefits:

• High switching capacity: Rated operating power at 400 V AC AC1 is as much as 263 kW, which guarantees handling even demanding loads.
• Safety first: Rated conditional short-circuit current Iq is 50 kA, which provides effective protection against the effects of short circuits.
• Universal mounting: Possibility of mounting on a plate, in distribution boards and front central increases installation flexibility.
• Durable construction: The device made of high-quality materials ensures long-lasting and trouble-free operation.
• Clarity and control: Long rotary handle makes operation and precise circuit switching easier.
• Versatile application: Reversing switch function allows for flexible configuration of the power system.
• Compliance with standards: Meets the required safety and quality standards.
• Solid connections: Cable lugs ensure secure and durable connection of wires with a cross-section of up to 185-240 mm².

Technical parameters in practice

The switch is characterized by a rated continuous current Iu at 400A, which means that it can safely operate with loads of this intensity for a long time. Rated operating voltage in the range of 380-690 V allows adaptation to different power systems. The ability to withstand short-circuit current Icw at 15 kA provides protection against the effects of sudden current surges. It is worth noting that there is no need to use additional electric drives or voltage releases – the device is ready to work immediately after installation. The degree of protection IP00 indicates the lack of protection against access to live parts and against the influence of the external environment – therefore, appropriate housing and operating conditions of the device should be ensured.
