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.
Product Overview
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.

FAQs
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
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
1. BKN-c Ics = 100% Icu
2. “10000” means Icn (10KA)
3. “3“ means Class 3
1. Data is a measured value.
2. Please use the measured value as a reference.
