KZS 2M2p EDI is a residual current circuit breaker with integral overcurrent protection with LED status signalisation.Combining the features of miniature circuit breaker and a residual current circuit breakerFeatures and advantages of KZS 2M2p EDIEasy and clear identification of the device status: - LED signalisation enables an exact information on which type of fault caused the tripping (red light for overload / short circuit, yellow light for residual current and green for manual operation) - Indication of internal contact position for quick and exact identification of the states of contacts (green for open contacts, red for closed contacts)Complete protection in one 2-module device: - KZSs combine the features of miniature circuit breakers and residual current circuit breakers - Increased immunity against unwanted tripping due to surge currents, generated by lightning or other disturbances - Energy limiting class 3: highest energy limiting performance for optimal protection of cable insulation and maximally reducing risk of fire and other damageStandardsIEC 61009-2,IEC 61009-1Easy and clean installation: The terminals enable connection through either cables or busbars, making the wiring operations easier and decreasing the number of cables, thus minimizing the required size of the distribution board.Type A protection: All KZS EDIs are sensitive to pure sinus residual current and pulsating direct current, making them suitable for installations with electronic devices (modern appliances, such as computers, washing machines etc.)Tested to endure temperatures down to -25°CTripping characteristic B and CRated short-circuit capacity 10 kA with 100 A / gG back-up fuseHigh stability of actual tripping residual currentTypical applicationsUsed primarily in circuits with an increased requirements regarding touchvoltage
