2 Overview Bulletin 40-MN / KTA -5 Compact bus-bar Supply block Blank space cover Auxiliary contact block for flush mounting Current limiter Supply block Auxiliary contact block for left side mounting Circuit-breaker 40-MN / KTA -5 Undervoltage trip for right side mounting Trip contact block Shunt trip for right side mounting Modular design for simple configuration Modular accessories enable the circuit-breakers to be fitted with auxiliary contacts, trip indicating auxiliary contacts and undervoltage or shunt trips simply and quickly to suit the specific application. High switching capacity reduces plant downtime Effective current limitation and low let-through energy (of the downstream contactor) enable normal operation to be resumed quickly after a short-circuit. Integrated automation systems The comprehensive range of accessories such as auxiliary contacts, trip indicating auxiliary contacts, undervoltage and shunt trips enable the circuit-breakers to be fully integrated in automatic control systems. Fast fault-finding Fault-finding and commissioning are made easy as information on switch and tripping statuses are signalled remotely and indicated locally. -

High switching capacity reduces plant downtime Effective current limitation and low let-through energy (of the downstream contactor) enable normal operation to be resumed quickly after a short-circuit. Integrated automation systems The comprehensive range of accessories such as auxiliary contacts, trip indicating auxiliary contacts, undervoltage and shunt trips enable the circuit-breakers to be fully integrated in automatic control systems. Fast fault-finding thanks to display of the right information Fault-finding and commissioning are made easy because information on switch and tripping statuses and the cause of tripping is signalled remotely by an auxiliary contact block and indicated locally. Use as main or EMERGENCY OFF switch The circuit-breakers type 40-CMN / KTA - comply with isolation requirements and can be used as main or EMERGENCY OFF switches. -

32 Time / Current Characteristic Circuit-breaker 40-CMN (KTA -) Tripping time [s] Circuit-breaker 40-MN (KTA -5) Tripping time [s] Multiple of the set current IeF ) Thermal release trip current: The adjustable inverse bimetal trip reliably protects motors against overloads. The curve shows the mean operating current at an ambient of 0 C starting from cold. Careful testing and setting ensures effective motor protection even in the case of singlephasing. Protection of EEx eii motors: A requirement of the German standard VE 0/8 is that the operating time of a thermal overload trip starting from cold must be less than the permissible heating time te of the motor. The relevant time / current characteristics must be available at the place of installation. If necessary, they can be obtained from the local sales office. According to VE 0/8, clause..4..., motor protection devices in new installations must provide protection even if one of the external connections is interrupted. 40-MN (KTA -5) circuit-breaker fulfils this requirement for motors with ratings up to kw. Additional protection must be provided to comply with it and also the requirement relating to the interruption of an external connection for motors with ratings higher than kw. 40-CMN (KTA -) circuit-breakers fulfill both requirements for all motor ratings. Multiple of the set current IeF ) Magnetic release trip current: The instantaneous magnetic trip has a fixed operating current setting. This corresponds to times the highest setting of the thermal overload trip. At the upper thermal release setting, this tripping current is times (40-MN / KTA -5 circuit-breaker) or 4 times (40-CMN / KTA - circuit-breaker) the set current; at a lower setting it is correspondingly higher. Current setting IeF: The overload trip corresponds to a thermal overload relay in a motor starter conforming to IEC 9-. If a different value is prescribed (e.g.reduced Ie for cooling medium having a temperature higher than 40 C or a place of installation higher than 000 m above sea level), the setting current is equal to the reduced rated current Ie of the motor. Note: The Bulletin 40 is only used for short-circuit protection in certain applications. The overload protection is provided by a thermal overload relay. Typical examples are variable speed motors, star / delta starters for heavy duty (high intertia) starting and / or an inadequately rated motor feeder. To ensure that only the downstream thermal overload relay trips, the set current IeF on the Bulletin 40 must be increased by 0 %. Product Selection Page - -
