Core offering

Nolta GmbH manufactures and sells motor protection devices and water level control products for industrial customers. Its portfolio covers Motorschutz (power connectors, changeover connectors, contactor combinations in 230V and 400V variants), level controllers (MS1, M2, M3, N1 pro) and float switches (KR1) for pump and tank applications, plus the NOLTAnet IoT add-on for remote monitoring of connected equipment.

Product overview

Nolta GmbH is a German manufacturer of motor protection and water technology products for the construction, pump, and manufacturing industries. The product portfolio consists of motor protection devices (Motorschutz) in 230V and 400V variants, including power connectors, changeover connectors, and contactor combinations; water technology products including level controllers (MS1, MS1 EX, M2, M3, N1 pro) and float switches (KR1); pump level control systems (Niveausteuerungen); and the NOLTAnet IoT module for remote monitoring. The company also offers an environmentally-focused 'R' series (MS1 R, KR1 R) made from recycled plastics. NOLTAnet is a key add-on that connects motor protection devices to enable IoT capabilities including device location tracking, error monitoring, switching cycle verification, and operating hours reading.
