Schneider Electric GB2CB05 Circuit Protector 0.50A 1P Din Rail

Product Description

The SCHNEIDER ELECTRIC GB2CB05 is a single-pole, DIN rail-mounted circuit protector rated at 0.50 amps, designed to protect branch circuits and control panel components from overload and short-circuit conditions. It uses a thermal-magnetic trip mechanism that responds to both sustained overloads and instantaneous fault currents, making it suitable for protecting low-current control circuits, instrumentation, and small motor loads. The toggle-switch reset actuator allows fast manual reset after a trip event. Installation is handled by licensed electricians or qualified control panel integrators working inside industrial or commercial control enclosures.

The GB2CB05 is used in industrial control panels, machine control assemblies, and building automation enclosures where low-amperage circuit protection is required on a DIN rail assembly. Its compact 15mm-wide footprint allows high-density breaker layouts in tight panel spaces. The backplate and clip mounting hardware accommodate standard DIN rail installations without additional hardware, making it a practical choice for panel builders and OEM equipment manufacturers.

Key Features

• Thermal-magnetic trip mechanism provides overload and short-circuit protection
• 0.50 amp rating suits low-current control circuits and instrumentation loads
• Single-pole configuration with toggle-switch reset actuator
• DIN rail mount with backplate and clip for tool-free rail installation
• Compact form factor fits high-density panel layouts
• Multiple breaking capacity ratings for varied fault-current environments

Compatibility

Designed as an OEM-style replacement or new-installation circuit protector for single-pole DIN rail control panel assemblies requiring thermal-magnetic trip protection at 0.50 amps.

Installation Notes

Installation should be performed by a licensed electrician or qualified panel integrator in accordance with NEC Article 240 and applicable local codes. De-energize the panel and verify zero voltage at all terminals before mounting or wiring the device. Clip the unit onto the DIN rail until it seats fully and confirm the backplate is secure before applying load wiring. Do not exceed the rated amperage of the device when sizing the protected circuit.
