GD Series Complete Molded Case Circuit Breakers, G Frame
EATON

• Eaton GD Series moulded case circuit breakers feature fixed thermal and fixed magnetic trips to protect against faulty currents:

Fixed Thermal Trips

• The thermal trip consists of a bimetallic strip which gets heated and bends when an overcurrent passes through the conductors, which opens the contacts and interrupts the current flow.

Fixed Magnetic Trips

• The magnetic trip has an electromagnetic component that detects the presence of short circuits in a circuit.
• As the current rises, a magnetic field is generated that trips the breaker and causes the contacts to open and stop the current flow.

• These units feature a fixed thermal and fixed magnetic trip unit to avoid nuisance tripping in mild current fluctuation but are highly sensitive to heavy inrush current, thus producing both instantaneous and time-delayed current limiting protection.
• They have a compact, space-saving design that provides installation in tight spaces and allows for high-speed blow-open action, resulting in superior performance.
• They are integrated with line and load side terminals for easy installation with panelboards and load centres.
• These MCCBs also include a toggle and a mechanical latching mechanism that ensures the circuit breaker remains in the tripped position until it is manually reset.
