The fireproof thermal magnetic trip
Circuit Breaker is a high-safety modular protection switch built with fireproof housing and dual thermal-magnetic tripping technology for comprehensive low-voltage circuit protection. Equipped with high-grade flame-retardant fireproof casing, this breaker can block open flames and resist high-temperature electric arcs effectively, preventing fire spread even under extreme circuit fault conditions. Its integrated thermal magnetic trip system realizes differentiated protection: thermal trip cuts off power gradually for long-term overload current, while magnetic trip responds instantly to sudden short-circuit current, avoiding false tripping and missing protection. With durable internal silver alloy contacts and optimized arc extinguishing structure, it ensures stable switching performance and long service life. It supports standard DIN rail mounting, fitting most distribution boxes and control cabinets for quick and space-saving installation.
This fireproof circuit breaker achieves fast and accurate power cutoff upon overload and short circuit faults, preventing cable overheating, electric arc ignition and electrical fires fundamentally thanks to its excellent fireproof performance. It eliminates critical electrical fire risks in power distribution circuits and greatly improves overall
Electrical Safety for residential, commercial and industrial electrical systems. It suppresses transient current spikes during equipment startup and grid fluctuation, and works well with matched circuit assemblies to provide reliable
Power Surge Protection against lightning-induced surges and abrupt grid voltage shocks.
This thermal magnetic trip circuit breaker meets international electrical safety and fire protection standards, and is highly compatible with common
Surge Protector modules and full-series wiring terminals. It never affects the working efficiency of matched circuit protection parts, delivering dual advantages of precise fault tripping and fire isolation to realize full-range
Power Protection for low-voltage power loops. Featuring outstanding fire resistance, accurate tripping precision, strong arc extinguishing capacity, stable contact conduction and easy rail installation, it is widely used in household power distribution, shopping mall electrical panels, factory workshop circuits, indoor engineering wiring and public building power supply systems. It is a high-safety fireproof protective breaker for demanding low-voltage electrical distribution projects.
