What is Hydraulic Magnetic Circuit Breaker
Hydraulic-Magnetic circuit breakers rely on a solenoid coil wound around a sealed tube containing an iron core, spring and damping fluid. When current exceeds the normal rating (overload), the magnetic field pulls the core-but the fluid introduces a controlled time-delay, allowing brief surges (like motor start-up) to pass without nuisance trips. In case of a large fault or short circuit, magnetic force alone triggers instant trip, cutting off power immediately. Unlike traditional thermal breakers, the trip threshold stays stable regardless of ambient temperature. As part of our portfolio, the CHINEHOW CVP TH Series uses this proven hydraulic-magnetic technology — delivering precise, temperature-stable, fast protection suitable for global industrial and commercial applications.
Feature
Precision
The CVP TH Series offers temperature-independent, hydraulic-magnetic protection with accurate trip curves that prevent nuisance shutdowns, ensuring reliable performance for sensitive electronics and industrial power systems.
Versatility
With current ratings from 1–50A and multiple actuator options, the breaker adapts to telecom power, industrial control panels, and equipment requiring stable, low-current overcurrent protection.
Durability
Robust panel-mount construction, M5 terminals, and vibration-resistant design provide long-lasting performance in harsh environments, including machinery, transportation, and continuous-duty power modules.
Compliance
Certified to UL489, TUV, CE, and CCC standards, the CVP TH Series supports global equipment integration, reducing certification effort and enabling seamless export to international markets.
Applications of Hydraulic Magnetic Circuit Breaker
Reliable, temperature-stable protection engineered for telecom, industrial control, and power system applications.
Telecom Power Systems
In telecom rectifiers, network racks, and base-station power modules, the CVP TH Series prevents nuisance trips caused by inrush currents. Users benefit from stable uptime, fewer service interruptions, and reliable protection for sensitive communication electronics.
Industrial Control Panels
Automation cabinets, PLC systems, and industrial machinery rely on precise trip curves to avoid unexpected shutdowns. With strong terminals and vibration resistance, users gain safer operation, easier maintenance, and dependable overload protection in demanding environments.

FAQs
Q: What makes a hydraulic magnetic circuit breaker different from a thermal breaker?
Hydraulic magnetic breakers trip based on magnetic force and hydraulic delay, not heat. This ensures accurate protection unaffected by ambient temperature and eliminates false trips.
Q: Can the CVP TH Series handle equipment inrush current?
Yes. The A4 delay curve allows short power-up surges from power supplies, UPS units, and telecom modules without unwanted shutdowns, improving system reliability.
Q: Is the CVP TH Series suitable for global equipment export?
Absolutely. With UL489, CE, TUV, and CCC certifications, the breaker meets major international safety standards and integrates smoothly into global projects.
Q: What installation method does the CVP TH Series support?
It uses a secure panel-mount design with M5 terminals, making it ideal for industrial control cabinets, telecom racks, and equipment with moderate vibration.
Q: Which actuator styles are available for the CVP TH Series?
Users can choose Short Handle, Long Handle, Flat Rocker, or Angle Rocker designs, ensuring the best fit for space constraints and operating preferences.
