Description
GYM9H-Z Miniature Circuit Breaker is designed for both AC and DC circuits:
AC applications: 50/60Hz, rated voltage 230/400V, rated current up to 63A.
DC applications: Rated voltage 220V, rated current up to 63A.
It provides overload and short-circuit protection and is suitable for infrequent switching operations of circuits under normal conditions.
This circuit breaker is widely applicable in industrial, commercial, high-rise buildings, and residential installations
Non-polarized circuit breakers do not require polarity distinction and can be connected in either direction, simplifying installation and reducing wiring errors. They are particularly suitable for applications where polarity may reverse, such as:Reversible motors,Battery charge/discharge switching,Bidirectional current protection including:EV charging/discharging circuits,Solar power systems (where battery current direction reverses),Industrial reversible drive systems.
The GYM9H-Z series non-polar DC circuit breaker is mainly used for short-circuit and overload protection in circuits, with rated working voltages of DC150V (1P), DC300V (2P), DC450V (3P), DC600V (4P),and rated currents of 16A~63A.
Function:
Overload Protection

Arc extinguishing
Poles: 2P; For L and N pole or + and – pole
Tripping Curves:B:(6±20%)In、C:(8.5±20%)In、D:(12±20%)In
FAST TRIP: The electromagnetic trip system can trip immediately when the circuit is short-circuited to protect the safety of the circuit.
Fast Arc Extinguishing Capability
Automotive circuit breakers, marine circuit breakers, fuses and other products do not have the ability to extinguish arcs. The higher the voltage, the larger the arc generated when on and off, and the easier it is to cause equipment to burn. Our circuit breakers have the ability to extinguish arcs, making it safe to switch on and off.
Thermal Magnetic Trip
When the circuit current exceeds the rated current of the circuit breaker, the circuit breaker will heat up and disconnect. The greater the current, the shorter the disconnection time.
The circuit breaker with thermal magnetic tripping characteristics will not trip instantaneously between 1-3 times the current
