Product FAQs
6 answersWhat types of enclosures and panels are compatible with the GD2050?
The GD2050 is a Series C, G-Frame molded case circuit breaker. It is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, motor control centers, and industrial enclosures that accept G-Frame unit-mount breakers.
Can the GD2050 be mounted on a DIN rail?
While the GD2050 is natively a unit-mount, bolt-on breaker, it can be adapted for standard 35mm DIN rail mounting using an Eaton DIN rail adapter kit. Otherwise, it mounts directly to a base plate or chassis rail in compatible panelboards.
Is the Eaton GD2050 suitable for direct current (DC) applications?
Yes, in addition to its AC ratings, the GD2050 is rated for 125/250VDC systems with an interrupting capacity of 10 kAIC. This makes it suitable for specific industrial DC control panels and battery systems requiring thermal-magnetic protection.
Does the GD2050 replace older Cutler-Hammer or Westinghouse breakers?
Yes, the Eaton GD2050 is a direct replacement for legacy Cutler-Hammer and Westinghouse Series C G-Frame breakers with the same 50A, 2-pole configuration.
Is the GD2050 HACR rated for HVAC applications?
Yes, the GD2050 is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 50A, 2-pole breaker for overcurrent protection.
Does the GD2050 come with line and load terminals installed?
Yes, the GD2050 features a feed-thru connection type and includes factory-installed line and load lugs. These standard lugs accept 14 AWG to 1/0 AWG copper or aluminum wire. Installers should reference the breaker nameplate for precise torque values during termination.
