Siemens 5SY4501-7 Supplementary Protector 1 Pole

Product Description

The SIEMENS 5SY4501-7 is a single-pole supplementary protector in the 5SY4 series, designed to provide overcurrent protection for branch circuits and individual loads in industrial and commercial control panel applications. Supplementary protectors differ from branch circuit breakers in that they are intended for use downstream of a branch circuit overcurrent device, protecting specific equipment or sub-circuits rather than the branch circuit itself. This unit is compact and rail-mountable, making it a practical fit for DIN-rail enclosures and control panels. Licensed electricians and panel builders are the primary installers of this device.

The SIEMENS 5SY4501-7 is suited for use in industrial control cabinets, machine tool panels, and commercial electrical enclosures where equipment-level overcurrent protection is required. Its single-pole configuration is appropriate for protecting 120-volt or single-phase loads within a larger panel assembly. The 5SY4 series is a recognized product line used across manufacturing, building automation, and process control environments.

Key Features

• Single-pole supplementary protector for equipment-level overcurrent protection
• Part of the SIEMENS 5SY4 series, designed for DIN-rail mounting in control enclosures
• Compact footprint suitable for high-density panel builds
• Provides downstream protection for sub-circuits and individual loads

Compatibility

Designed as an OEM-style supplementary protector for use in DIN-rail-mounted control panels and enclosures requiring single-pole overcurrent protection.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize the panel and verify absence of voltage before installing or replacing the protector. This device is a supplementary protector and must be installed downstream of a listed branch circuit overcurrent protective device. Confirm that the enclosure and downstream load ratings are compatible with this device before energizing.
