- 【Specification】Polos: 1P, Voltage: DC 250V, Current: 100A, Breaking Capacity up to 6KA, Breaking Time ≤ 0.03 S. ***Tip：The circuit breaker makes a strange noise when it shakes because we have added an arc extinguishing cover, which is not fixed inside. Therefore, the shaking causes the noise, and this is a normal situation
- 【Strong Protection Features】The circuit breaker effectively protects 250V DC circuits from overload and short circuit damage. When the current exceeds 5 times the rated value, the circuit breaker will trip after 8 seconds; when the current exceeds 10 times the rated value, the circuit breaker will trip immediately, preventing damage to electrical appliances. The trip time is only 0.03 seconds, ensuring circuit safety and reliability
- 【High-Quality Materials】 Made with high-precision molds, high closure accuracy; full copper contact pieces with conductivity 10 times higher than pure brass. The switch can handle up to 6000 on-off cycles, which is twice that of older models
- 【Detail Improvements】Larger screw heads for easier and safer wire connections, 12 built-in arc extinguishing plates, 3 more than older models, effectively preventing flashover and arc, stronger outer shell, ensuring stability and preventing disassembly during tripping
- 【Key Selling Points】Supports screw or terminal block connection with a high breaking capacity of 6KA, unique heat dissipation system for stable operation over long periods, new latch design for easier operation. The scene display design allows for easy identification
- 100 amp 3 pole breaker is compatible with 120/240V electrical systems, making it a versatile choice for a wide range of applications and installations. Its plug-on design ensures easy installation and fit for Siemens Type EQ, EQL, SEQ, EQG PL and ES Series load centres.
- This device is designed to protect electrical circuits from damage caused by overloading or short circuits. When a fault occurs, 100 amp three pole type qp circuit breaker automatically cuts off the flow of electricity, preventing potential hazards and equipment damage.
- Thermal magnetic protection mechanism uses a powerful magnetic force to trip the breakers 3 pole 100 amp quickly in response to a short-circuit. This helps prevent further damage to the system and ensures the safety of occupants and property.
- 100 amp circuit breaker is made of high quality insulation material. Insulation safety, fireproof and anti-drop, strong oxidation resistance and long service life.Produced by TLmathus professional manufacturer.
- Q3100 breaker not only makes it compatible with residential load center and appliance circuit breaker panels, micro commercial distribution panels, pool equipment distribution panels, residential transfer distribution switch panels, making it suitable for most applications.
- FUNCTIONS: Used to protect power distribution facilities from overload and short-circuit damage, and can also be used for control and isolation.
