Modular power switch 3x40A HIM304

Modular power switch – reliable installation control

This three-pole power switch with a rated current of 40A is a solid solution for controlling electrical circuits in residential and commercial buildings. Designed for mounting in distribution boards, it provides safe and convenient power switching. The design allows it to function as a safety switch, maintenance switch, and main circuit breaker, making it a versatile element of any electrical installation.

Functionality and application

The HIM304 switch is designed to operate in systems with a voltage of 380-415V AC. Its construction based on a locking mechanism guarantees stability and safety of use. Thanks to the ability to switch between I-O-II modes, it allows for flexible load management and easy power disconnection when needed. It is ideal for installations requiring frequent circuit switching, e.g. during maintenance or renovation work. The possibility of mounting on a plate further increases its versatility.

Advantages for installers and users

• Versatility: Safety switch, maintenance switch and main breaker function in one device – saving space and costs.
• Safety: Locking mechanism prevents accidental disconnection of power during operation.
• Durability: Solid construction of a permanently mounted device ensures long-lasting and reliable operation.
• Easy installation: Designed for mounting in standard distribution boards, with screw connections for conductors with a cross-section of 1.5 - 16 mm².
• High performance: Rated operating power for AC-23 at 400V is as much as 18 kW, and the switching capacity at 400V is 26 kW.
• Short-circuit protection: Rated withstand current Icw is 1.26 kA, and conditional short-circuit current Iq is 50 kA – effective protection of the installation against the effects of failures.
• Wide operating temperature range: From -20°C to 70°C – possibility of use in various environmental conditions.
• Clear markings: Gray color of the control element makes it easier to identify the switch in the distribution board.
