Xbkb1li-63 small leakage circuit breaker only alarms without trippingXbkb1li-63 small series small leakage circuit breaker (electronic type) scope of application and functional characteristics
Xbkb1li-63 small series small leakage circuit breaker is applicable to the power supply system with rated working voltage of 230 (400) V and 50Hz. It is used as direct contact protection (I △ n ≤ 30mA) and indirect contact protection to prevent fire caused by insulation damage of electrical equipment. The circuit breaker also has the functions of overload and short circuit protection of the line. The product has beautiful and compact appearance, light weight, excellent and reliable performance, high breaking capacity, track installation, high flame retardant and impact resistant plastics for shell and components, and long service life.
Main technical parameters: rated insulation voltage Ue: 690V, rated working voltage Ue: 230 (400V), shell level, rated current: 6a, 10a, 16a, 20a, 25A, 32a, 40a, 50a, 63A, rated current 6 ~ 63A. The number of poles is 1p + N and 2p.
Functional features:Leakage action current I △ n: (30) 50mA ~ 500mA.
Leakage action time: non delay < 0.1sLeakage alarm and tripping function:
1. Alarm first and then trip - the alarm starts when the leakage current reaches o.65i △ n ± 10%, and trips when the leakage current reaches o.8i △ n ± 10%.
2. Only alarm without tripping - when the leakage current reaches I △ n ± 10%, alarm but do not trip.
3. Alarm form - buzzer sound signal in circuit breaker.-Special auxiliary contact action for external connection (contact capacity AC220V, 3a).
