Modular disconnector Eti-Polam SV 463 4P 63A, 4-pole 63 A

Eti-Polam SV 463 4P 63A is a modular four-pole disconnector designed for DIN-rail installation in electrical distribution boards. It provides manual switching and positive isolation of low-voltage circuits up to 63 A, with a visible open/closed indication that helps confirm circuit status during maintenance and service work. The compact modular body is compatible with standard distribution enclosures and intended for coordinating with protection devices and safe isolation of multiple conductors at once.

Advantages

The disconnector offers clear mechanical indication of contact position, robust manual operation and a compact form factor suitable for standard DIN-rail systems. It supports simultaneous disconnection of four poles, enabling isolation of three phases plus neutral in a single device. The design ensures electrical separation for maintenance and helps integrate with protective devices to improve overall system safety and serviceability.

Suitable for

• Isolation of three-phase circuits with neutral in residential and commercial distribution boards
• Manual disconnection for maintenance and service work on low-voltage installations
• Use as a switching element to coordinate with circuit breakers and protective relays
• Retrofit or new installations requiring a compact 4-pole isolator on DIN-rail

Key specifications

• Number of poles: 4-pole (four simultaneous contacts)
• Rated current: 63 A
• Mounting: DIN-rail compatible modular enclosure
• Operation: manual handle for positive open/closed switching
• Indication: visible mechanical indicator of contact position
• Application voltage: suitable for low-voltage distribution systems (three-phase plus neutral)

How to use

Install the modular disconnector on a standard DIN-rail inside the distribution board following local wiring regulations. Connect incoming and outgoing conductors to the corresponding terminals, ensuring tight and secure terminations and proper conductor sizing for the 63 A rating. Operate the manual handle to open or close all four poles simultaneously; verify the visible indicator to confirm the open (isolated) or closed (connected) state before performing maintenance. Always de-energize and verify absence of voltage with appropriate test instruments when carrying out live work.

Usage recommendations

Use this 4-pole disconnector in coordination with upstream protection devices and according to applicable electrical standards. Ensure periodic visual inspection and torque checks on terminal connections. For safe isolation, follow lockout/tagout procedures and verify that auxiliary circuits are also de-energized before maintenance.
