Modular disconnector EATON HIS-100/4 4-pole 100 A (MPN 142831)

EATON HIS-100/4 is a modular 4-pole disconnector rated for 100 A, designed to provide clear and reliable isolation of electrical circuits. The device is intended for DIN-rail mounting in distribution boards, industrial control panels and commercial electrical installations where simultaneous disconnection of all poles is required for maintenance and safety. The product enables visible and secure separation of live conductors to meet operational and safety procedures.

Advantages

The modular disconnector offers four-pole isolation in a compact DIN-rail housing, enabling full separation of three phases and neutral in a single device. Its 100 A current rating supports common distribution and feeder circuits in commercial and industrial environments. The unit is designed for straightforward integration into standard distribution systems and provides a recognizable switch position for verification of disconnection. The construction emphasizes reliable mechanical operation and compatibility with modular mounting systems.

Suitable for

• Distribution boards in commercial and industrial premises
• Isolation of three-phase loads with neutral conductors
• Maintenance and safety switching in control panels
• Feeder circuits and sub-distribution lines

Key specifications

• Number of poles: 4 (three phases + neutral)
• Rated current: 100 A
• Mounting: DIN-rail modular housing
• Function: Visible disconnection/isolation of all poles
• Application environment: Distribution boards, industrial panels, commercial installations

How to use

Install the modular disconnector on a standard DIN rail within the distribution board or panel, following local electrical codes and installation practices. Connect the incoming and outgoing conductors to the designated terminals for the three phases and neutral, ensuring proper torque and conductor preparation. Use the manual operating mechanism to place the device in the open position when performing maintenance; verify visible isolation and, if required by procedure, additionally test for absence of voltage before working on the circuit. Re-engage the switch only after all work is complete and safety checks have been performed.

Usage recommendations

Use this 4-pole, 100 A modular disconnector where simultaneous and visible isolation of all conductors is required. Ensure compatibility with system current and mounting space, and perform installation and inspections in accordance with applicable electrical standards and safety regulations.
