Motor starter MS18-14A 004600350

Motor starter – reliable protection for your installation

This three-pole motor starter from ETI Polam, model MS18-14A, is a key element in protecting electric motors and circuits associated with them. Designed to operate in networks with a voltage of 230-690V, it provides effective protection against overloads and short circuits, minimizing the risk of failure and downtime. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation in demanding industrial conditions.

Functionality and application

The MS18-14A starter is designed to protect motors with a power of up to 7.5 kW (at 400V) and 4 kW (at 230V). Thanks to the adjustable overload release range of 9-14A, it can be adapted to the specific needs of various applications. The thermal-magnetic release method ensures a quick response to both overloads and short circuits. Additional phase failure sensitivity increases operational safety by protecting the motor from damage in the event of a loss of one of the supply phases. The starter finds application in a wide range of devices, such as pumps, fans, conveyors and production machines.

Key features and benefits

• Versatility: The ability to use it in installations with a voltage of 230-690V makes it a universal solution for many applications.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity at 12.5 kA at 400V AC guarantees effective disconnection of the circuit in the event of a short circuit, protecting the remaining elements of the installation.
• Thermal-magnetic protection: The combination of thermal and magnetic protection provides comprehensive protection of the motor against various types of failures. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
• Safety: Phase failure sensitivity further protects the motor from damage caused by voltage asymmetry.
• Mounting: The device is permanently mounted using frame clamps, ensuring a stable connection and easy installation in the switchboard.
• Compliance with standards: The product meets European quality standards (BBJ, VDE, NEMKO, FIMKO, DEMKO) and has ISO 9001 and ISO 14000 certificates confirming a high production standard.
• Durability: Made of high-quality materials, it ensures long-lasting and reliable operation even in harsh industrial conditions.
