Explosion-proof magnetic starters serve functions such as safe startup and prevention of remote control.

Safe Start: The explosion-proof magnetic starter utilizes magnetic drive technology, enabling easy device activation without contact, effectively avoiding safety hazards. Suitable for various types of high-power equipment, such as electric motors, generators, air conditioners, etc. Prevention: The explosion-proof magnetic starter employs special sealing and isolation techniques to prevent external gases from entering the internal circuit, thereby avoiding risks caused by electric sparks. Remote Control: The explosion-proof magnetic starter features remote control functionality, allowing for remote start or stop of equipment without the need for on-site operation, greatly improving work efficiency and safety. Overload Protection: The explosion-proof magnetic starter also includes multiple protection functions such as overload protection and short-circuit protection, effectively preventing fires caused by electrical faults. The explosion-proof magnetic starter is primarily used in hazardous locations containing gas mixtures of Class II, Group B or C, T4 group and below, to control the start, stop, or reversal of three-phase asynchronous motors, and provides overload and short-circuit protection.
The magnetic starter housing is made of ZL102 aluminum alloy die-casting or steel plate welding, with high-voltage electrostatic spraying on the surface, and is equipped with stainless steel exposed fasteners, giving the product an aesthetically pleasing appearance. It adopts a composite, modular structure, with each circuit freely assemblable as needed. Generally, the switch box uses a flameproof structure, while the busbar box and outlet box use an increased safety structure. It contains AC contactors, thermal relays, control buttons or switches, and can be operated on the box or remotely, as well as from two locations, featuring breaking, overload, undervoltage protection, and automatic short-circuit cutoff functions. Customization is available according to customer requirements, such as adding surge protectors, ammeters, voltmeters, etc., and can be equipped with an external padlock metal handle. Suitable for controlling multiple motors, each branch can be equipped with circuit breaker protection, and can also provide power for lighting or instruments.
Both conduit and cable wiring are acceptable. Complies with GB3836-2000 and IEC60079 standards.
