Eaton HIS-40/4 Modular Switch-Disconnector 40A 4P

The Eaton HIS-40/4 Modular Switch-Disconnector is a professional-grade electrical component engineered for the secure isolation of electrical circuits. Designed for integration into distribution boards, this 4-pole device provides a reliable solution for disconnecting power during maintenance or emergency situations. Its robust construction ensures consistent performance and safety in both residential and industrial electrical installations.

Advantages

This switch-disconnector offers high operational reliability and durability, making it an essential component for modern electrical systems. Its modular design allows for seamless installation on standard DIN rails, ensuring compatibility with a wide range of distribution board configurations. By providing a clear physical separation of circuits, it enhances safety for personnel performing maintenance tasks, while its high-quality materials guarantee long-term operational stability under standard load conditions.

Suitable for

• Residential electrical distribution boards
• Commercial building power management
• Industrial control panels
• Safe isolation of electrical circuits during maintenance

This device is not intended for use as a motor starter or for frequent load-switching operations where high-frequency arc suppression is required. It is strictly a switch-disconnector and does not provide overcurrent or short-circuit protection, meaning it must be used in conjunction with appropriate circuit breakers or fuses.

Key specifications

• Rated current: 40A
• Number of poles: 4
• Mounting type: DIN rail
• Application: Electrical circuit isolation

To install the Eaton HIS-40/4, mount the device onto a standard DIN rail within your distribution board. Ensure that all electrical connections are tightened to the manufacturer's specified torque settings to prevent overheating. Once installed, the toggle switch allows for manual operation to connect or disconnect the power supply to the downstream circuit.

What to consider before purchase

• Verify that the 40A current rating is sufficient for your specific circuit load.
• Ensure there is adequate space on the DIN rail within your distribution board.
• Confirm that the 4-pole configuration meets your system's wiring requirements.

Always ensure the power supply is disconnected before performing any installation or maintenance work on the electrical system. Regularly inspect the switch for any signs of wear or damage to maintain optimal safety standards.
