Miniature Circuit Breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.
Miniature Circuit Breakers are placed directly above the load and are designed to protect final loads.
They are ideal for protection of circuits in industrial, commercial, and residential sectors, and ensures the following functions: protection against short-circuit and overload currents, isolation, and protection against indirect contact.
Protection: Short circuit & Overload (AC & DC)
Rated current: 1~63A 1, 2, 3, 4 Poles
Multi-function terminal: Screw, Lug & Ring tongue
Rated breaking capacity: 6~10kA at 120/277/240/480Y
Rail mounting: UL489 & 489DC, UL486E (Lug), UL1077, IEC 60898, IEC 60947-2, IEC 61008, IEC 61009

MCB BK63N, 2 pole, 6A, C curve, 6kA, is rated at 415V, can the MCB be applied in a 100 / 110V operating system?
This is possible because the voltage that the customer is trying to use is lower than the specification authentication voltage. Specification certification voltage: AC415V The voltage the customer is trying to use: AC100/110V
There is one more question regarding RKN – is there value of rated breaking capacity for ground leak current?
1. IΔm=Im : 500 or 10In
Simply put, it must be 10In or at least 500A
2. in detail by the rated current
RKN 25A : IΔm = 500A
RKN 32A : IΔm = 500A
RKN 40A : IΔm = 500A
RKN 63A : IΔm = 630A
Please help me explain to customer some claim on MCB (BKN-c) 1. Why there is no information about Icu&Ics in catalogue 2. Please explain the symbol (10000/3) highlighted yellow color as picture below.
1. BKN-c Ics = 100% Icu
2. “10000” means Icn (10KA)
3. “3“ means Class 3
Request you to please check whether you have any data regarding the impedance value for RKN & RKN-b ELCBs.
1. Data is a measured value.
2. Please use the measured value as a reference.
