Schneider Electric GB2CB20 Circuit Protector 12A 1P Din Rail

Product Description

The SCHNEIDER ELECTRIC GB2CB20 is a 12-amp, 1-pole 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 overcurrent and short-circuit conditions. The toggle switch reset actuator allows quick manual reset after a trip event. Mounting options include backplate, clip, and DIN rail configurations, providing flexibility for a variety of enclosure types. Licensed electricians and panel builders typically specify this device for motor branch circuit protection and control circuit applications where compact, reliable overcurrent protection is required.

The GB2CB20 is suited for use in motor control centers, machine control panels, and industrial distribution boards where DIN rail-mounted circuit protection is standard practice. Its compact footprint and multiple breaking capacity ratings make it appropriate for tight panel layouts in both new construction and retrofit scenarios. This device is intended for installation by qualified electrical professionals working with low-voltage control and power circuits in commercial and light industrial environments.

Key Features

• 12-amp rated current with 1-pole configuration for single-phase circuit protection
• Thermal-magnetic trip mechanism provides both overload and short-circuit protection
• Toggle switch reset actuator for fast manual reset after trip
• DIN rail, backplate, and clip mounting options for installation flexibility
• Multiple breaking capacity ratings to suit varying fault current environments
• Compact form factor suited for dense panel layouts

Compatibility

Designed as an OEM-style replacement or new-installation circuit protector for DIN rail-equipped industrial and commercial control panels requiring 12-amp, 1-pole thermal-magnetic overcurrent protection.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before mounting or wiring the device. Verify that the panel bus and wiring are rated for the circuit voltage and the breaking capacity required by the application. Do not exceed the device rated current or attempt to defeat the trip mechanism.
