Thermal Magnetic Residual MCCB TDK1L

TDK1L series molded case circuit breaker is used for AC 50/60Hz, rated working voltage of 400V,  rated insulation voltage of 800V, rated working current up to 630A. Used for frequent conversion in circuit and infrequent starting of motor. The rated residual operating current and the maximum breaking time can be adjusted according to the actual situation. Be able to protect lines and power supply equipment from damage, and can also provide protection against long-term grounding faults that cannot be detected by overcurrent protection, which may cause fire hazards. The conventional leakage protection module with residual current protection circuit breaker is sampled as two phases, and this series of circuit breakers is three phases. If any phase is lost, the leakage protection module of circuit breaker can still work normally.

    Scope of Application

    TDK1L series molded case circuit breaker is used for AC 50/60Hz, rated working voltage of 400V,rated insulation voltage of 800V, rated working current up to 630A.

    Used for frequent conversion in circuit and infrequent starting of motor.The rated residual operating current and the maximum breaking time can be adjusted accordingto the actual situation.

    Be able to protect lines and power supply equipment from damage, and can also provide protectionagainst long-term grounding faults that cannot be detected by overcurrent protection, which maycause fire hazards.

    The conventional leakage protection module with residual current protection circuit breakeris sampled as two phases, and this series of circuit breakers is three phases. If any phase is lost, theleakage protection module of circuit breaker can still work normally.

    Comply with IEC60947-2 standard.With the functions of overload, short circuit, leakage and undervoltage protection.With leakage alarm output function.Comply the electromagnetic compatibility requirements of Appendix B in IEC60947The full series of circuit breakers has isolation function, and its symbol is_
