Latest Siemens 5SY4106-7 Supplementary Protector 1P 240V

The SIEMENS 5SY4106-7 is a single-pole supplementary protector rated for 240 volts, designed to provide overcurrent protection for branch circuits and equipment loads in light industrial and commercial electrical systems. Supplementary protectors differ from standard branch-circuit breakers in that they are intended for use downstream of a primary overcurrent device, offering a compact and reliable means of protecting individual loads such as control panels, power supplies, and motor circuits. Licensed electricians install this device in equipment enclosures and control assemblies where space-efficient, UL-recognized overcurrent protection is required.

This protector is suited for single-pole applications in 240-volt systems, making it appropriate for a range of light commercial and industrial control equipment. It fits into DIN-rail-mounted enclosures commonly found in control panels, machine tooling setups, and building automation equipment. The compact form factor allows installation in tight panel layouts without sacrificing reliable overcurrent protection.

Key Features

• Single-pole design simplifies wiring in space-limited control enclosures
• 240-volt rating covers common light commercial and industrial circuit requirements
• Compact footprint: 4 inches long by 3 inches wide by 1 inch deep
• Lightweight at 0.34 pounds, minimizing added load on panel assemblies
• Supplementary protector classification for use downstream of primary overcurrent protection

Compatibility

Designed as an OEM-style supplementary protector for single-pole 240-volt branch circuit protection applications in control panels and equipment enclosures requiring a DIN-rail-mountable overcurrent device.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and equipment manufacturer guidelines. De-energize the panel and verify the absence of voltage before handling or mounting the protector. This device is intended for use downstream of a primary branch-circuit overcurrent protective device and should not be used as a replacement for branch-circuit breakers where code requires listed branch-circuit protection. Confirm the enclosure rating and mounting rail compatibility before installation.
