The YCB7-63N series miniature circuit breaker are suitable for overcurrent protection building line facilities and similar purposes in AC 50/60Hz, rated voltage 230V/400V,
General
1.Protection againstoverload and short-circuit currents
2.Protection against theeffects of sinusoidal alternating earthfaultcurrents
3.Protection against indirect contacts and additional protection against directcontacts.
4.Protection against fire hazard causedbyinsulation faults
5.Used in residentialbuilding
6.According tothe type of instantaneous release classified as follows:type B(3-5)In,type C(5-10)In
General
Function description:Whena phase of L1,L2,L3 overvoltaged,undervoltaged orphase lacked,the relaywill be disconnected andautomatically search for the normalphase,and switch to open the relay of the normal phase,switching priority
L1>L2>L3!
Function
1. Personnel and fire protection
2. Cable and line protection against overload and short-circuits.
Selection
1. I∆n ≤ 30 mA: additional protection in the case of direct contact.
2. I∆n ≤300 mA: preventative fire protection in the case of ground fault currents.
3. AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.
The Signal Lamp is applicable to circuit with rated voltage 230V~and frequency 50/60Hz for visual indication and signaling.
General
The Modular Voltage Meter is applicable to circuit with rated frequency 50/60Hz for measure and display digital voltage.
