Schneider Electric GB2CB09 Circuit Protector 4A 1P Din Rail

Product Description

The SCHNEIDER ELECTRIC GB2CB09 is a 1-pole, 4-amp circuit protector designed for DIN rail mounting in industrial and commercial control panel applications. It uses a thermal-magnetic trip mechanism to protect downstream equipment from overloads and short-circuit faults. The toggle-switch reset actuator allows for quick manual reset after a trip event. At 0.12 pounds and a compact footprint, this device installs efficiently in space-constrained enclosures and control cabinets. Licensed electricians and panel builders working on machine control, HVAC controls, and process equipment will encounter this type of device as a branch-circuit protective component for low-current loads.

This circuit protector is suited for use in residential, commercial, and light industrial control panel builds where individual circuit protection is required on DIN rail-mounted assemblies. Typical applications include motor control centers, HVAC control panels, and automation enclosures where branch circuits serving low-current devices require reliable overcurrent protection. The single-pole configuration and DIN rail clip mounting allow it to be installed alongside other DIN-mounted devices in a standard panel layout. Its compact width allows dense panel layouts without sacrificing protection capability.

Key Features

• Thermal-magnetic trip mechanism provides protection against both sustained overloads and short-circuit faults
• Toggle-switch reset actuator allows fast manual reset after a trip event
• DIN rail clip mounting with backplate compatibility simplifies installation in standard enclosures
• 1-pole configuration rated at 4 amps for low-current branch circuit protection
• Compact form factor supports dense panel layouts

Compatibility

Designed as an OEM-style replacement or new-installation circuit protector for standard DIN rail-mounted control panel assemblies requiring 1-pole, 4-amp thermal-magnetic branch circuit 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 this device. Clip the unit firmly onto the DIN rail and confirm the latch is fully seated before restoring power. Do not exceed the rated amperage of the device when sizing protected circuits.
